Robot Framework Interview Questions

Basic Robot Framework Interview Questions

1. What are the benefits of using Robot Framework for test automation?

Solution: Robot Framework offers several benefits for test automation, including ease of use with its keyword-driven approach, which allows even non-programmers to write tests. It supports multiple test libraries, making it highly extensible. The framework is also open-source, platform-independent, and integrates well with other tools. Its readable syntax, reusable test cases, and detailed reporting make test automation efficient and scalable.

2. Explain Robot Framework Architecture?

Solution: Robot Framework is an Independent framework that uses Keyword Driven Testing. All the users can create high-level keywords from the existing keywords.

Test Data is the First Layer used in maintaining data and inputting it to the Robot Framework.

Robot Framework is a primary advantage and agnostic of the target under test.

Test Libraries are used in interacting with other layers by using Libraries and making them portable and maintainable.

System Under Test is an actual target on which all the Testing Activities can be performed.

3. What are the names of all the file formats which are supported in the Robot framework?

Solution: In Robot Framework, we usually use the files written in basic text format (usually written in the .robot form or the format of .txt), or we can also use the files written in the Tab-separated format or TSV. Data written in plain text format can then be embedded in files in structured text format.

4. What are the Features of Robot Framework?

Solution: Following are the features of the Robot Framework: 

• Robot Framework has a High-Level Architecture
• Robot Framework has Simple Tabular Syntax
• Robot Framework provides Clear Reports
• Robot Framework has Generic Test Libraries
• Robot Framework provides Detailed Logs
• Robot Framework separates Test Data Editor.

5. What do you mean by a Jenkins Freestyle Project?

Solution: This is a fundamental question regarding robot framework interview questions; however, it is imperative. As you go up the corporate ladder to the business that recruited you, you will understand that Jenkins' project is critical. Jenkins' project is nothing more than a series of tasks that can be swiftly repeated to get comparable outcomes, and these stages also include the activities that must be taken after the build is complete.

You will find all the standard features you need to flesh out your project. Some necessities like the ability to build and configure triggers for security for the entire project. You can even parameterize your entire project.

6. What are the disadvantages of using the robot framework?

Solution: Following are the disadvantages of using the robot framework:

• Debugging capability is omitted: The product lacks options for the standard breakpoint configuration. As a result, a user must employ time slips or display something different in the log.
• Many difficulties in the Ride IDE: When using the "text editor" mode and the tabular mode, the program will occasionally crash. It's also worth noting that some third-party plugins aren't compatible with specific libraries because autocomplete isn't available (for example, SeleniumLibrary).
• Support for third-party extensions and libraries is unstable: This framework does not support previously developed libraries. Of course, you can make your own, but this is pointless because such extensions cannot be used often.

7. What is the use of Robot Framework?

Solution: Robot Framework is a generic test automation framework for acceptance testing and acceptance test-driven development (ATDD). It is a keyword-driven testing framework that uses tabular test data syntax.

8. What are environment variables in the context of the robot framework?

Solution: The %{ENV_VAR_NAME} syntax in Robot Framework allows you to use environment variables in your test data. They're only allowed to use string values. By separating the variable name and the default value with an equal sign, such as %{ENV_VAR_NAME = default_value}, you can give a default value that will be used if the environment variable does not exist.

Environment variables set in the operating system before the test execution are available during it. The keywords Set Environment Variable and Delete Environment Variable, both available in the OperatingSystem library, can be used to create new ones or delete existing ones. Because environment variables are global, environment variables defined in one test case can be reused in subsequent test cases. On the other hand, changes to environment variables are ineffective after the Test has been completed.

9. Name the three different types of variables that are available in the robot framework?

Solution:  The three types of variables present in the robot framework are, Scalar variable, List variable, and last but not least dictionary variable.

10. What is keyword-driven style in the context of the robot framework?

Solution: When Workflow tests, like the Valid Login test, are made up of several keywords and their possible arguments, it is called keyword-driven style. In the Valid Login example, the system is first put into the initial state (Open Login Page), then something is done to it (Input Name, Input Password, Submit Credentials), and lastly, the system is confirmed to have performed as intended (Welcome Page Should Be Open).

11. What are standard libraries in the Robot Framework? Name the standard libraries.

Solution: Some test libraries are distributed with Robot Framework, which is called standard libraries. The BuiltIn library is unique because it is automatically taken into use; thus, its keywords are always available.

Other standard libraries need to be imported the same way as any other libraries, but there is no need to install them. The typical standard libraries are BuiltIn, Collections, DateTime, Dialogs, OperatingSystem, Process, Screenshot, String, Telnet, and XML.

12. What is a data-driven design style in the context of the robot framework?

Solution: Another technique for writing test cases is the data-driven approach, which hides the test workflow using only one higher-level keyword, commonly created as a valid keyword. These tests come in handy when you need to test the same scenario with various input and output data. Although it would be possible to utilize the same keyword in each Test, the test template functionality allows you to define the keyword just once.

13. What is Setup and TearDown in Robot Framework?

Solution: Setup - this instruction is used in executing the test suite or test case.

TearDown - this instruction can run and execute the test suite and case.

14. What are the differences between Robot Framework and Selenium?

Solution:  The main difference between Robot Framework and Selenium can be seen below:

15. What is the meaning of the test setup, and what do you mean by teardown?

Solution: The test setup, as the name might suggest, is something that is used to set up the testing conditions, so obviously, the test setup phase comes before the Test's execution. For Teardown, again, the name is indicative enough of all that may be done in this process. Teardown usually is executed after the test case has finished its run time. In the paradigm of the Robot framework, both Test and Teardown are nothing but keywords, and they can be used with their proper arguments.

Advanced Robot Framework Interview Questions

16. Distinguish between the Robot Framework and Cucumber.

Robot Framework: The Robot Platform open-source automation framework supports acceptance testing, acceptance test-driven development (ATTD), and robotic process automation (RPA). It uses a keyword-driven testing technology technique and may be extended using testing libraries written in Python or Java.

Cucumber: Cucumber is a testing tool for behavior-driven development (BDD) (BDD). It gives way for developing tests that everyone can understand, independent of technical experience. Users (business analysts and product owners) submit scenarios or acceptance tests that explain the system's behavior from the customer's perspective for examination and approval by the product owners before developers create their programs. The Cucumber framework makes use of the Ruby programming language.

17. What keyword will you use to register a mouse hover-over event on any web element?

The Mouseover keyword, found in the Selenium2Library, will be used to recognize a mouse over any web element.

18. What do you mean by selenium library object locators?

The following is the solution to the robot framework interview questions. The selenium library has a set of locators that may be used to correctly locate the position of any GUI element on the screen. The selenium IDE contains several different sorts of locators. These object locators have names like ID, Name, Class, LinkText, etc.

19. What is the dependency name you must need to install and use the RIDE editor?

The dependencies and packages that you need to install and use the RIDE editor are wxPython and pywin32.

20. What are the three kinds of variables accessible in the robot framework?

The robot framework has three different sorts of variables: scalar variables, list variables, and dictionary variables.

21. Assume that we are performing a test case that is more keyword-driven than utilizing actual data. We are dissatisfied with the test case's performance, which predominantly uses the term. As a result, we believe we must change the keyword-driven test case into a data-driven test case. How will you handle it? Please provide an example.

The robot framework includes specialized libraries, one of which is known as the standard library. The standard library contains many codes designed expressly to test and automate applications. All standard libraries may be imported into your application in the same manner that you would like any other code library.

The only thing to remember is that you do not need to install these libraries individually. These libraries are very remarkable. The explanation is simple: you may utilize the terms from these standard libraries since they are always available. Standard library names include Collections, DateTime, Dialogs, OS, ScreenShot, XML, etc.

22. Would you be able to alter the speed at which the test cases in the Selenium library are executed?

Yes, we have a lot of control when using the selenium extension or code library. You may control the speed at which the test cases are performed using the term Speed.

RIDE makes it easier to write test cases by offering framework-specific code completion and syntax highlighting. The editor makes it simple to create a project, test suite, test case, keywords, variables, import the library, execute, and tag the test case.

26. In Robot Framework, how can I read a file?

The Robot Framework Excel library can read XLS, XLSX, and CSV file extensions. It includes the keywords required to process these files.

The OPEN EXCEL statement is the most important term in the Excel Library. Including a Library statement mentioning DataDriver in the Test, the Case file is critical. If the statement refers to an Excel or CSV file, the DataDriver will read each row or record in the file. The OPEN EXCEL statement can also be accessed in a Robot Framework Resource file.

27. How do you create test cases in the Robot Framework?

Right-click on the project to begin writing a test case in RIDE. Click the New Test Case button. Enter the test case's name and click OK. Three tabs are displayed for the newly constructed test case: Edit, Text Edit, and Run. You may also create a robot file in PyCharm, under the project. Double-click it to open it and begin creating the sections, followed by the settings, variables, test cases, and supportive keyword functions.

28. Who came up with the Robot Framework?

Pekka Klärck's master's thesis in 2005 laid the groundwork for the Robot Framework. The initial version was created the same year at Nokia Networks. Version 2.0 was made available as open-source software on June 24, 2008, and version 3.0.2 was made available on February 7, 2017.
