What is Robot Framework?

Robot Framework is a free and open-source automation framework that is used for robotic process automation (RPA), acceptance testing, and acceptance test-driven development (ATDD). It creates test cases in a format that is easy for humans to read and understand by using tabular syntax.

Developed in Python, Robot Framework can be extended with test libraries implemented using Python or Java. Some key features of Robot Framework include:

• Tabular test case syntax for easy test creation
• Support for keyword-driven and data-driven testing
• Extensive library support for activities like REST API testing, database testing, image recognition, etc.
• Detailed logs and reports
• Built-in tools for test case debugging
• Integration with various CI/CD tools like Jenkins, TeamCity, etc.

• Integration with SVN and Git for version control
• Test suite management and execution
• Logs, reports, and xUnit compatible result files

RIDE provides a productive environment for testers to work with Robot Framework.

Robot Framework Interview Questions on Test Cases

Q5. What are the different types of variables used in Robot Framework?

There are three types of variables in Robot Framework:

• Scalar Variables – Single value variables like ${NAME} or ${2}
• List Variables – Variables containing list of values like @{COLORS}
• Dictionary Variables – Key-value pair variables like &{USER}

Q6. How can you parameterize test cases in Robot Framework?

Some ways to parameterize test cases in Robot Framework are:

• Use scalar, list, and dictionary variables to pass arguments to keywords
• Leverage data-driven testing to run tests against data from external files
• Create reusable keywords with arguments for common test logic
• Use built-in FOR loop keywords to iterate over data sets
• Import variables from external resource files for better test reuse

Q7. How can you implement conditional logic in Robot Framework test cases?

Some ways to implement conditional logic in Robot Framework test scripts are:

• Use Run Keyword If and Run Keyword Unless keywords
• Leverage Boolean conditionals like Should Be Equal
• Implement keyword logic using IF/ELSE conditions in Python/Java
• Use Robot Framework metrics and statics API from listeners to control flow
• Create custom run-time keywords that return Boolean status

Robot Framework Interview Questions on Execution

Q8. How can you execute specific test cases in Robot Framework?

Some ways to execute specific test cases are:

• Use –test option to specify test case names to execute
• Apply tags to test cases and use –include or –exclude options
• Set Suite Setup/Teardown to control suite execution
• Use Set Tags keyword to dynamically tag tests cases for conditional execution

Q9. How can you import test libraries in Robot Framework?

There are two main ways to import test libraries:

• Use Library keyword passing library name and optional arguments
• Import library Python/Java files containing keywords

For example:

*** Settings ***Library  SeleniumLibrary*** Test Cases ***Login Test    Open Browser  http://example.com  Chrome    Input Text  name:username  demo    Input Password  name:password  Test1234    Submit Form    Close Browser
