20 Robot Framework Interview Questions and Answers

Robot Framework is a generic open-source test automation framework for acceptance testing and acceptance test-driven development. It is a keyword-driven testing approach that uses tabular test data syntax. If you are applying for a position that requires the use of Robot Framework, you should expect to be asked questions about it during your interview. In this article, we will review some of the most common Robot Framework questions and how you can answer them.

Robot Framework Interview Questions and Answers

Here are 20 commonly asked Robot Framework interview questions and answers to prepare you for your interview:

1. What is Robot Framework?

Robot Framework is a generic open source automation framework for acceptance testing, acceptance test driven development (ATDD), and robotic process automation (RPA).

2. Can you explain the difference between a test case and a keyword in Robot Framework?

A test case is a collection of one or more keywords that are used to test a specific functionality in your application. A keyword is a single action that is performed as part of a test case. For example, a keyword could be used to open a web browser and navigate to a specific URL.

3. How do you use keywords to build test cases in Robot Framework?

You can use keywords to build test cases in Robot Framework by creating keyword-driven tests. This means that you will create a test case by creating a keyword for each action that you want the test case to perform. For example, if you want to test a login feature, you would create a keyword for entering the username, another keyword for entering the password, and a keyword for clicking the login button.

4. Is it possible to write custom libraries for Robot Framework? If yes, how?

Yes, it is possible to write custom libraries for Robot Framework. This can be done in Python or Java.

5. What are some advantages of using the Robot Framework?

The Robot Framework is a great tool for automating testing and for creating test cases that are easy to read and maintain. It also has a large community and many plugins and extensions that can be used to extend its functionality.

6. Does the Robot Framework require any specific operating system or programming language to run?

No, the Robot Framework is designed to be operating system and programming language independent. This means that it should be able to run on any operating system that supports Python (which is the language used to write Robot Framework tests) and it should also be able to interface with any programming language that has a Robot Framework library available for it.

7. Is there an IDE available that makes working with Robot Framework easier? If so, what are its features?

Yes, there are a few IDEs available that make working with Robot Framework easier. Some of the features that these IDEs offer include syntax highlighting, code completion, and debugging support.

8. What are the different types of files created when using Robot Framework? Explain their purpose as well.

When using Robot Framework, there are four different types of files that are created: resource files, variable files, test case files, and data files. Resource files contain all of the keywords that can be used in your tests. Variable files store variables that can be used across multiple tests. Test case files contain the actual tests that will be executed. Data files contain the data that will be used by the tests.

9. Why do you think Robot Framework is better than other frameworks like Selenium WebDriver?

I believe that Robot Framework is better than other frameworks like Selenium WebDriver because it is more user-friendly and has a lot of features that other frameworks do not have. For example, Robot Framework has built-in support for keyword-driven testing, data-driven testing, and modular testing. Additionally, Robot Framework can be used with a wide variety of programming languages and can be easily integrated with a number of Continuous Integration tools.

10. Are there any limitations to using Robot Framework?

There are a few potential limitations to be aware of when using Robot Framework. One is that it is not well suited for handling dynamic content. Another is that it can be difficult to use for testing complex workflows. Finally, it can be challenging to integrate with existing test infrastructure.

11. What’s the best way to install Robot Framework on Windows?

The best way to install Robot Framework on Windows is to use the pip installer. You can find the pip installer at https://pypi.python.org/pypi/pip. Once you have pip installed, you can use it to install Robot Framework by running the following command:

pip install robotframework

12. What does the Test Setup keyword do?

The Test Setup keyword is used to set up the environment for a test or suite of tests. This keyword is typically used to set up variables or connect to a database.

13. What does the Run Keyword And Continue On Failure keyword do?

The Run Keyword And Continue On Failure keyword will execute the specified keyword, but will not stop the test if the keyword fails. This is useful for keywords that are not critical to the test, but you still want to know if they fail.

14. What is the difference between the Fail and Exit For Loop keywords?

The Fail keyword will immediately stop the current test, while the Exit For Loop keyword will only exit the current loop iteration and continue with the next iteration.

15. What type of data can be passed to a keyword via a variable file?

You can pass integers, floats, strings, lists, dictionaries, and tuples to a keyword via a variable file.

16. What is the difference between the Run Keyword And Expect Error keyword and the Run Keyword And Ignore Error keyword?

The Run Keyword And Expect Error keyword will cause the test to fail if the keyword that is executed does not throw an error, while the Run Keyword And Ignore Error keyword will cause the test to continue even if the keyword that is executed throws an error.

17. What is the most common usage scenario for if/else conditionals in Robot Framework?

The most common usage scenario for if/else conditionals in Robot Framework is when you want to check if a certain condition is true or false, and then take different actions depending on the result. For example, you might want to check if a certain element is present on a page, and if it is, you want to click on it. If the element is not present, you want to take some other action.

18. What happens if two libraries have the same name but are located in different directories? Which one will be used by default?

If two libraries have the same name but are located in different directories, the library located in the directory that is listed first in the path will be used by default.

19. If a library has no __init__ method, how does Python know which class to load from the library?

When a library has no __init__ method, Python will automatically load the class from the library that has the same name as the library.

20. What is the difference between running a script directly versus importing the contents of a script into another script?

When you run a script directly, the entire script is executed as a single unit. When you import the contents of a script into another script, the imported script is executed as part of the larger script. This can be useful if you want to reuse code from one script in another script.
