Although test case names can contain any character, using? Test cases can also have their own settings. Setting names are always in the second column, where keywords normally are, and their values are in the subsequent columns.

Setting names have square brackets around them to distinguish them from keywords. The available settings are listed below and explained later in this section.

Setting names are case-insensitive, but the format used above is recommended. Settings used to be also space-insensitive, but that was deprecated in Robot Framework 3. Possible spaces between brackets and the name e. The Setting section can have the following test case related settings. These settings are mainly default values for the test case specific settings listed earlier. The earlier examples have already demonstrated keywords taking different arguments, and this section discusses this important functionality more thoroughly.

How to actually implement user keywords and library keywords with different arguments is discussed in separate sections. Keywords can accept zero or more arguments, and some arguments may have default values.

What arguments a keyword accepts depends on its implementation, and typically the best place to search this information is keyword's documentation. In the examples in this section the documentation is expected to be generated using the Libdoc tool, but the same information is available on documentation generated by generic documentation tools such as pydoc.

Most keywords have a certain number of arguments that must always be given. In the keyword documentation this is denoted by specifying the argument names separated with a comma like first, second, third.

The argument names actually do not matter in this case, except that they should explain what the argument does, but it is important to have exactly the same number of arguments as specified in the documentation.

Using too few or too many arguments will result in an error. The test below uses keywords Create Directory and Copy File from the OperatingSystem library. Their arguments are specified as path and source, destination , which means that they take one and two arguments, respectively.

The last keyword, No Operation from BuiltIn , takes no arguments. Arguments often have default values which can either be given or not. It is possible that all the arguments have default values, but there cannot be any positional arguments after arguments with default values.

Trying to use it without any arguments or more than three arguments would not work. It is also possible that a keyword accepts any number of arguments. These so called varargs can be combined with mandatory arguments and arguments with default values, but they are always given after them. The former can be used with any number of arguments, but the latter requires at least one argument. The named argument syntax makes using arguments with default values more flexible, and allows explicitly labeling what a certain argument value means.

Technically named arguments work exactly like keyword arguments in Python. This is especially useful when multiple arguments have default values, as it is possible to name only some the arguments and let others use their defaults. If this sounds complicated, the named arguments example below hopefully makes it more clear. The named argument syntax is both case and space sensitive.

The relative order of the named arguments does not matter. It is possible to use variables in both named argument names and values. If the value is a single scalar variable , it is passed to the keyword as-is. This allows using any objects, not only strings, as values also when using the named argument syntax. If variables are used in named argument names, variables are resolved before matching them against argument names.

The named argument syntax requires the equal sign to be written literally in the keyword call. This is important to remember especially when wrapping keywords into other keywords.

This is illustrated by the example below. If keyword needs to accept and pass forward any named arguments, it must be changed to accept free named arguments. See free named argument examples for a wrapper keyword version that can pass both positional and named arguments forward. The named argument syntax is used only when the part of the argument before the equal sign matches one of the keyword's arguments.

In this case the argument foo either incorrectly gets the value quux or, more likely, there is a syntax error. Note that escaping is not needed if there are no arguments with name foo , but because it makes the situation more explicit, it may nevertheless be a good idea.

As already explained, the named argument syntax works with keywords. In addition to that, it also works when importing libraries.

Naming arguments is supported by user keywords and by most test libraries. The only exceptions are Python keywords explicitly using positional-only arguments. The following example demonstrates using the named arguments syntax with library keywords, user keywords, and when importing the Telnet test library. Free named arguments are supported by same keyword types than normal named arguments.

How keywords specify that they accept free named arguments depends on the keyword type. Free named arguments support variables similarly as named arguments. In practice that means that variables can be used both in names and values, but the escape sign must always be visible literally. An extra limitation is that free argument names must always be strings. As the first example of using free named arguments, let's take a look at Run Process keyword in the Process library.

The example below also shows that variables work with free keyword arguments exactly like when using the named argument syntax. As the second example, let's create a wrapper user keyword for running the program. py in the above example. The wrapper keyword Run Program accepts all positional and named arguments and passes them forward to Run Process along with the name of the command to execute. Starting from Robot Framework 3. This syntax is inspired by the keyword-only arguments syntax supported by Python 3.

For most parts named-only arguments work the same way as named arguments. The main difference is that libraries implemented with Python 2 using the static library API do not support this syntax. As an example of using the named-only arguments with user keywords , here is a variation of the Run Program in the above free named argument examples that only supports configuring shell :. A totally different approach to specify arguments is embedding them into keyword names.

This syntax is supported by both test library keywords and user keywords. A test case fails if any of the keyword it uses fails.

Normally this means that execution of that test case is stopped, possible test teardown is executed, and then execution continues from the next test case.

It is also possible to use special continuable failures if stopping test execution is not desired. The error message assigned to a failed test case is got directly from the failed keyword. Often the error message is created by the keyword itself, but some keywords allow configuring them. In some circumstances, for example when continuable failures are used, a test case can fail multiple times. In that case the final error message is got by combining the individual errors. Very long error messages are automatically cut from the middle to keep reports easier to read, but full error messages are always visible in log files as messages of the failed keywords.

By default error messages are normal text, but they can contain HTML formatting. This marker will be removed from the final error message shown in reports and logs. Using HTML in a custom message is shown in the second example below. The test case name comes directly from the Test Case section: it is exactly what is entered into the test case column. Test cases in one test suite should have unique names. It is available whenever a test is being executed, including all user keywords, as well as the test setup and the test teardown.

If the variable does not exist, its name is left unchanged. The [Documentation] setting allows you to set a free documentation for a test case. That text is shown in the command line output, as well as the resulting test logs and test reports. It is possible to use simple HTML formatting in documentation and variables can be used to make the documentation dynamic.

Possible non-existing variables are left unchanged. If documentation is split into multiple columns, cells in one row are concatenated together with spaces. If documentation is split into multiple rows , the created documentation lines themselves are concatenated using newlines. Newlines are not added if a line already ends with a newline or an escaping backslash.

It is important that test cases have clear and descriptive names, and in that case they normally do not need any documentation. If the logic of the test case needs documenting, it is often a sign that keywords in the test case need better names and they are to be enhanced, instead of adding extra documentation.

Finally, metadata, such as the environment and user information in the last example above, is often better specified using tags. Using tags in Robot Framework is a simple, yet powerful mechanism for classifying test cases and also user keywords. Tags are free text and Robot Framework itself has no special meaning for them except for the reserved tags discussed below. Tags can be used at least for the following purposes:.

As the example shows, tags can be created using variables, but otherwise they preserve the exact name used in the data. When tags are compared, for example, to collect statistics, to select test to be executed, or to remove duplicates, comparisons are case, space and underscore insensitive.

The Test Tags setting is new in Robot Framework 6. Earlier versions support Force Tags and Default Tags settings discussed below. Prior to Robot Framework 6.

Both of these settings still work, but they are considered deprecated. A visible deprecation warning will be added in the future, most likely in Robot Framework 7. Tools like Tidy can be used to ease transition.

Robot Framework 6. Instead of using a separate setting that tests can override, tests can use syntax -tag with their [Tags] setting to tell they should not get a tag named tag.

This syntax does not yet work in Robot Framework 6. Users are generally free to use whatever tags that work in their context. There are, however, certain tags that have a predefined meaning for Robot Framework itself, and using them for other purposes can have unexpected results. All special tags Robot Framework has and will have in the future have the robot: prefix.

To avoid problems, users should thus not use any tag with this prefixes unless actually activating the special functionality. The current reserved tags are listed below, but more such tags are likely to be added in the future. As of RobotFramework 4. Robot Framework has similar test setup and teardown functionality as many other test automation frameworks. In short, a test setup is something that is executed before a test case, and a test teardown is executed after a test case.

In Robot Framework setups and teardowns are just normal keywords with possible arguments. Setup and teardown are always a single keyword. If they need to take care of multiple separate tasks, it is possible to create higher-level user keywords for that purpose. An alternative solution is executing multiple keywords using the BuiltIn keyword Run Keywords.

The test teardown is special in two ways. First of all, it is executed also when a test case fails, so it can be used for clean-up activities that must be done regardless of the test case status. In addition, all the keywords in the teardown are also executed even if one of them fails. This continue on failure functionality can be used also with normal keywords, but inside teardowns it is on by default.

The easiest way to specify a setup or a teardown for test cases in a test case file is using the Test Setup and Test Teardown settings in the Setting section. Individual test cases can also have their own setup or teardown. They are defined with the [Setup] or [Teardown] settings in the test case section and they override possible Test Setup and Test Teardown settings. Having no keyword after a [Setup] or [Teardown] setting means having no setup or teardown.

The name of the keyword to be executed as a setup or a teardown can be a variable. This facilitates having different setups or teardowns in different environments by giving the keyword name as a variable from the command line.

Test suites can have a setup and teardown of their own. A suite setup is executed before any test cases or sub test suites in that test suite, and similarly a suite teardown is executed after them. Test templates convert normal keyword-driven test cases into data-driven tests. Whereas the body of a keyword-driven test case is constructed from keywords and their possible arguments, test cases with template contain only the arguments for the template keyword.

Template keywords can accept both normal positional and named arguments, as well as arguments embedded to the keyword name. Unlike with other settings, it is not possible to define a template using a variable. How a keyword accepting normal positional arguments can be used as a template is illustrated by the following example test cases.

These two tests are functionally fully identical. As the example illustrates, it is possible to specify the template for an individual test case using the [Template] setting. An alternative approach is using the Test Template setting in the Setting section, in which case the template is applied for all test cases in that test case file. The [Template] setting overrides the possible template set in the Setting section, and an empty value for [Template] means that the test has no template even when Test Template is used.

It is also possible to use value NONE to indicate that a test has no template. If a templated test case has multiple data rows in its body, the template is applied for all the rows one by one. This means that the same keyword is executed multiple times, once with data on each row.

Templated tests are also special so that all the rounds are executed even if one or more of them fails. It is possible to use this kind of continue on failure mode with normal tests too, but with the templated tests the mode is on automatically.

Using keywords with default values or accepting variable number of arguments , as well as using named arguments and free named arguments , work with templates exactly like they work otherwise. Using variables in arguments is also supported normally. Templates support a variation of the embedded argument syntax. With templates this syntax works so that if the template keyword has variables in its name, they are considered placeholders for arguments and replaced with the actual arguments used with the template.

The resulting keyword is then used without positional arguments. This is best illustrated with an example:. When embedded arguments are used with templates, the number of arguments in the template keyword name must match the number of arguments it is used with.

The argument names do not need to match the arguments of the original keyword, though, and it is also possible to use different arguments altogether:. The main benefit of using embedded arguments with templates is that argument names are specified explicitly. When using normal arguments, the same effect can be achieved by naming the columns that contain arguments.

This is illustrated by the data-driven style example in the next section. If templates are used with FOR loops , the template is applied for all the steps inside the loop. The continue on failure mode is in use also in this case, which means that all the steps are executed with all the looped elements even if there are failures. This can be useful, for example, when used together with FOR loops to filter executed arguments. There are several different ways in which test cases may be written.

Test cases that describe some kind of workflow may be written either in keyword-driven or behavior-driven style. Data-driven style can be used to test the same workflow with varying input data.

Workflow tests, such as the Valid Login test described earlier , are constructed from several keywords and their possible arguments.

Their normal structure is that first the system is taken into the initial state Open Login Page in the Valid Login example , then something is done to the system Input Name , Input Password , Submit Credentials , and finally it is verified that the system behaved as expected Welcome Page Should Be Open.

Another style to write test cases is the data-driven approach where test cases use only one higher-level keyword, often created as a user keyword , that hides the actual test workflow. It would be possible to repeat the same keyword with every test, but the test template functionality allows specifying the keyword to use only once. Naming columns like in the example above makes tests easier to understand. This is possible because on the header row other cells except the first one are ignored.

When using test templates , all the rounds in a test are executed even if there are failures, so there is no real functional difference between these two styles. In the above example separate combinations are named so it is easier to see what they test, but having potentially large number of these tests may mess-up statistics.

Which style to use depends on the context and personal preferences. It is also possible to write test cases as requirements that also non-technical project stakeholders must understand. These executable requirements are a corner stone of a process commonly called Acceptance Test Driven Development ATDD or Specification by Example.

When writing test cases in this style, the initial state is usually expressed with a keyword starting with word Given , the actions are described with keyword starting with When and the expectations with a keyword starting with Then.

Keyword starting with And or But may be used if a step has more than one action. Prefixes Given , When , Then , And and But are dropped when matching keywords are searched, if no match with the full name is found. This works for both user keywords and library keywords. For example, Given login page is open in the above example can be implemented as user keyword either with or without the word Given.

Ignoring prefixes also allows using the same keyword with different prefixes. For example Welcome page should be open could also used as And welcome page should be open.

These prefixes can be localized. When writing concrete examples it is useful to be able to pass actual data to keyword implementations.

User keywords support this by allowing embedding arguments into keyword name. In addition to test automation, Robot Framework can be used for other automation purposes, including robotic process automation RPA. It has always been possible, but Robot Framework 3. For most parts creating tasks works the same way as creating tests and the only real difference is in terminology. Tasks can also be organized into suites exactly like test cases. Tasks are created based on the available keywords exactly like test cases, and the task syntax is in general identical to the test case syntax.

The main difference is that tasks are created in Task sections instead of Test Case sections:. Settings that can be used in the task section are exactly the same as in the test case section. In the setting section it is possible to use Task Setup , Task Teardown , Task Template and Task Timeout instead of their Test variants.

Robot Framework test cases are created in test case files, which can be organized into directories. These files and directories create a hierarchical test suite structure. Same concepts apply also when creating tasks , but the terminology differs. Robot Framework test cases are created using test case sections in test case files. Such a file automatically creates a test suite from all the test cases it contains.

There is no upper limit for how many test cases there can be, but it is recommended to have less than ten, unless the data-driven approach is used, where one test case consists of only one high-level keyword. Test case files can be organized into directories, and these directories create higher-level test suites. A test suite created from a directory cannot have any test cases directly, but it contains other test suites with test cases, instead.

These directories can then be placed into other directories creating an even higher-level suite. There are no limits for the structure, so test cases can be organized as needed. When a test directory is executed, the files and directories it contains are processed recursively as follows:.

If a file or directory that is processed does not contain any test cases, it is silently ignored a message is written to the syslog and the processing continues. A test suite created from a directory can have similar settings as a suite created from a test case file.

Because a directory alone cannot have that kind of information, it must be placed into a special test suite initialization file. The name format is borrowed from Python, where files named in this manner denote that a directory is a module.

Initialization files have the same structure and syntax as test case files, except that they cannot have test case sections and not all settings are supported. Variables and keywords created or imported in initialization files are not available in the lower level test suites. If you need to share variables or keywords, you can put them into resource files that can be imported both by initialization and test case files.

The main usage for initialization files is specifying test suite related settings similarly as in test case files , but setting some test case related settings is also possible. How to use different settings in the initialization files is explained below. The test suite name is constructed from the file or directory name.

The name is created so that the extension is ignored, possible underscores are replaced with spaces, and names fully in lower case are title cased. The file or directory name can contain a prefix to control the execution order of the suites.

The prefix is separated from the base name by two underscores and, when constructing the actual test suite name, both the prefix and underscores are removed. robot create test suites Some Tests and More Tests , respectively, and the former is executed before the latter.

The documentation for a test suite is set using the Documentation setting in the Setting section. It can be used in test case files or, with higher-level suites, in test suite initialization files.

Test suite documentation has exactly the same characteristics regarding to where it is shown and how it can be created as test case documentation. Both the name and documentation of the top-level test suite can be overridden in test execution. This can be done with the command line options --name and --doc , respectively, as explained in section Setting metadata.

Test suites can also have other metadata than the documentation. This metadata is defined in the Setting section using the Metadata setting. Metadata set in this manner is shown in test reports and logs.

The name and value for the metadata are located in the columns following Metadata. The value is handled similarly as documentation, which means that it can be split into several cells joined together with spaces or into several rows joined together with newlines , simple HTML formatting works and even variables can be used.

For top-level test suites, it is possible to set metadata also with the --metadata command line option. This is discussed in more detail in section Setting metadata. Not only test cases but also test suites can have a setup and a teardown.

A suite setup is executed before running any of the suite's test cases or child test suites, and a test teardown is executed after them. All test suites can have a setup and a teardown; with suites created from a directory they must be specified in a suite initialization file.

Similarly as with test cases, a suite setup and teardown are keywords that may take arguments. They are defined in the Setting section with Suite Setup and Suite Teardown settings, respectively.

Keyword names and possible arguments are located in the columns after the setting name. If a suite setup fails, all test cases in it and its child test suites are immediately assigned a fail status and they are not actually executed. This makes suite setups ideal for checking preconditions that must be met before running test cases is possible. A suite teardown is normally used for cleaning up after all the test cases have been executed.

It is executed even if the setup of the same suite fails. If the suite teardown fails, all test cases in the suite are marked failed, regardless of their original execution status.

Note that all the keywords in suite teardowns are executed even if one of them fails. Test libraries contain those lowest-level keywords, often called library keywords , which actually interact with the system under test. All test cases always use keywords from some library, often through higher-level user keywords.

This section explains how to take test libraries into use and how to use the keywords they provide. Creating test libraries is described in a separate section. Test libraries are typically imported using the Library setting, but it is also possible to use the Import Library keyword. Test libraries are normally imported using the Library setting in the Setting section and having the library name in the subsequent column.

Unlike most of the other data, the library name is both case- and space-sensitive. If a library is in a package, the full name including the package name must be used. In those cases where the library needs arguments, they are listed in the columns after the library name.

It is possible to use default values, variable number of arguments, and named arguments in test library imports similarly as with arguments to keywords. Both the library name and arguments can be set using variables. It is possible to import test libraries in test case files , resource files and suite initialization files. In all these cases, all the keywords in the imported library are available in that file.

With resource files, those keywords are also available in other files using them. Another possibility to take a test library into use is using the keyword Import Library from the BuiltIn library.

This keyword takes the library name and possible arguments similarly as the Library setting. Keywords from the imported library are available in the test suite where the Import Library keyword was used. This approach is useful in cases where the library is not available when the test execution starts and only some other keywords make it available. Libraries to import can be specified either by using the library name or the path to the library.

These approaches work the same way regardless if the library is imported using the Library setting or the Import Library keyword. The most common way to specify a test library to import is using its name, like it has been done in all the examples in this section. In these cases Robot Framework tries to find the class or module implementing the library from the module search path. Libraries that are installed somehow ought to be in the module search path automatically, but with other libraries the search path may need to be configured separately.

The biggest benefit of this approach is that when the module search path has been configured, often using a custom start-up script , normal users do not need to think where libraries actually are installed.

The drawback is that getting your own, possible very simple, libraries into the search path may require some additional configuration. Another mechanism for specifying the library to import is using a path to it in the file system. This path is considered relative to the directory where current test data file is situated similarly as paths to resource and variable files.

The main benefit of this approach is that there is no need to configure the module search path. If the library is a file, the path to it must contain extension, i. With absolute paths the trailing slash is optional. Following examples demonstrate these different usages. A limitation of this approach is that libraries implemented as Python classes must be in a module with the same name as the class. The library name is shown in test logs before keyword names, and if multiple keywords have the same name, they must be used so that the keyword name is prefixed with the library name.

The library name is got normally from the module or class name implementing it, but there are some situations where changing it is desirable:. The basic syntax for specifying the new name is having the text AS case-sensitive after the library name and then having the new name after that.

The specified name is shown in logs and must be used in the test data when using keywords' full name LibraryName. Keyword Name. Possible arguments to the library are placed between the original library name and the AS marker.

The following example illustrates how the same library can be imported several times with different arguments:. Setting a custom name to a test library works both when importing a library in the Setting section and when using the Import Library keyword.

The old syntax continues to work, but it is considered deprecated and will eventually be removed. Some test libraries are distributed with Robot Framework and these libraries are called standard libraries. The BuiltIn library is special, because it is taken into use automatically and thus its keywords are always available. Other standard libraries need to be imported in the same way as any other libraries, but there is no need to install them.

In addition to the normal standard libraries listed above, there is also Remote library that is totally different than the other standard libraries. It does not have any keywords of its own but it works as a proxy between Robot Framework and actual test library implementations. These libraries can be running on other machines than the core framework and can even be implemented using languages not supported by Robot Framework natively. See separate Remote library interface section for more information about this concept.

Any test library that is not one of the standard libraries is, by definition, an external library. The Robot Framework open source community has implemented several generic libraries, such as SeleniumLibrary and SwingLibrary , which are not packaged with the core framework. Generic and custom libraries can obviously also be implemented by teams using Robot Framework. See Creating test libraries section for more information about that topic.

Different external libraries can have a totally different mechanism for installing them and taking them into use. Sometimes they may also require some other dependencies to be installed separately. All libraries should have clear installation and usage documentation and they should preferably automate the installation process. Variables are an integral feature of Robot Framework, and they can be used in most places in test data.

Most commonly, they are used in arguments for keywords in Test Case and Keyword sections, but also all settings allow variables in their values. A normal keyword name cannot be specified with a variable, but the BuiltIn keyword Run Keyword can be used to get the same effect. If a non-existent variable is used in the test data, the keyword using it fails. Different ways how to create variables are discussed in the subsequent sections.

Robot Framework variables, similarly as keywords, are case-insensitive, and also spaces and underscores are ignored. Much more importantly, though, case should be used consistently. Unlike in some programming languages where similar variable syntax is used, curly braces are always mandatory.

Variable names can basically have any characters between the curly braces. However, using only alphabetic characters from a to z, numbers, underscore and space is recommended, and it is even a requirement for using the extended variable syntax.

When this syntax is used, the variable name is replaced with its value as-is. Most of the time variable values are strings, but variables can contain any object, including numbers, lists, dictionaries, or even custom objects. The example below illustrates the usage of scalar variables. above, its value is first converted into a string and then concatenated with the other data. The example below demonstrates the difference between having a variable in alone or with other content.

Finally, when this test data is executed, different keywords receive the arguments as explained below:. Converting variables to Unicode obviously fails if the variable cannot be represented as Unicode. A workaround is creating a variable that contains the whole value and using it alone in the cell e. If a variable value is a list or list-like, it is also possible to use it as a list variable like {EXAMPLE}. In this case the list is expanded and individual items are passed in as separate arguments.

This is easiest to explain with an example. Assuming that a variable {USER} has value ['robot', 'secret'] , the following two test cases are equivalent:.

Binary Options Trading is a relatively new way to trade the markets. You need to know about the movement of the price and how that might affect future prices. This is something that comes with heavy risk and should only be traded with money you can afford to lose. We will try and help you learn about binaries, but nowhere will we guarantee you will make money.

You should not consider this site as trading advice. Please be very diligent when it comes to this. This is how they work: you pick an underlying asset, a stock, a currency, a commodity, basically anything that the binary option broker offers, then you decide whether the price will move in one direction or the other.

A call option should be used when you think the price will increase, a put option is for when you think there will be a drop in price. Once you decide where you think the underlying asset will move you select how much you want to risk. The items you trade are actually underlying assets, and not the assets themselves. Binary Options Trading does not give you ownership of the assets you invest in.

Assets have predictable price fluctuations, you can use this to your advantage. You can find trades with an expiration time just a few minutes in the future or up to a month long.

This appeals to both day traders and position traders alike. You know exactly how much you will get in return when your trades are successful. Some brokers offer refunds on losing trades, some up to 15 percent. This cushion can help over the long run. Refunds like this are most beneficial to traders just getting their feet wet, but they remain a good choice for almost everyone in the market. Make sure that you are getting a good return on your winning trades as well, however. Sometimes a low winning percentage will offset the refund amount.

New traders need to look out for their best interests. Having a high payout return on winning trades is the best place to start looking.

Obviously, you want to make as much money as possible, so it only makes sense to start out by trading with the sites that offer the highest returns. But different brokers have different rates for different time frames and different underlying assets. We are here to make your search a little easier. Our reviews will help you to wade through the waters of selecting a trading site. For new traders, you should focus on one type of trade until you have mastered a demo trading account.

Expert Option demo is very popular among traders and if you are from USA, you should definitely check the Nadex demo. Trading too erratically will only hurt you.

No matter the circumstance a demo account will show you some things and keep you out of a lot of risky situations. Just be ready when it comes to switching. Every hour, hundreds of thousands of trades are made in various financial markets, such as Forex, commodities, CFDs, indices, and cryptocurrencies. The brains executing these trades may be of very experienced and seasoned traders or those of new entrants in the market.

Trading binary options can be overwhelming, especially for amateur and beginner traders, as one is expected to deal with a lot of data and information when making trades on a regular basis.

The next step is to provide your personal information such as name, address, and contact information. We advise you to share real information as brokers are bound by law to verify your account and your account can be blocked if you provide faulty or misleading information.

Personal information can be verified independently by the broker, or they can also ask you to upload your ID or one of the utility bills. Traders often refrain from uploading a scan of bills or ID and do not get registered. This is not the right decision because the broker is legally bound to verify your ID from these documents. The last but most important part is choosing the payment method for your account.
