 1. What is Robot Framework? 

Robot Framework is an open-source test automation framework for acceptance testing and acceptance test-driven development (ATDD). It uses a keyword-driven approach and a simple tabular syntax, making it easy to create tests that are readable and maintainable. It is written in Python and can be extended with a large number of libraries for automating different technologies. 

2. What are the main advantages of using Robot Framework? 

The main advantages are: 

• It allows you to write human-readable test cases, which improves collaboration between technical and non-technical team members. 
• It is highly extensible and platform-independent, supporting web, mobile, API, and desktop automation through its rich library ecosystem. 
• It is keyword-driven, which promotes the reuse of code and makes test scripts easier to maintain. 
• It provides excellent, detailed HTML reports and logs out of the box, which makes debugging and analyzing test results simple. 

3. Explain the architecture of Robot Framework. 

Robot Framework has a layered architecture. 

• The Test Data layer is at the top, containing the test case files written in the simple, tabular format. 
• The Robot Framework Core is the middle layer. It parses the test data, finds the corresponding keywords, and executes them. 
• The Test Libraries layer is at the bottom. This layer contains the implementation of the keywords. These can be standard libraries (like the BuiltIn library), external libraries (like SeleniumLibrary), or custom libraries created in Python. 

4. What are keywords in Robot Framework? 

Keywords are the central part of Robot Framework. They are commands that perform a specific action, like Click Button or Input Text. They are used to write the actual steps of a test case. There are two main types of keywords: 

• Library Keywords: These are provided by imported libraries (e.g., Open Browser from SeleniumLibrary). 
• User-Defined Keywords: These are keywords that you create yourself by combining other keywords. They are used to create higher-level, reusable actions.

5. What are the four main tables (sections) in a Robot Framework file? 

A Robot Framework file is organized into four distinct sections, also known as tables. Each is identified by a header with asterisks. They are: 

• Settings: For importing libraries, resources, and defining suite-level metadata like documentation and setups. 
• Variables: For defining test variables that are accessible within the entire suite. 
• Test Cases: This is where the actual test cases are defined using a sequence of keywords. 
• Keywords: For creating user-defined keywords, which are reusable combinations of other keywords. 

6. What is the difference between a Library and a Resource file? 

A Library provides the low-level keywords that interact with the system under test. They are typically implemented in Python (e.g., SeleniumLibrary). You import them in the Settings section using Library LibraryName. 

A Resource file is a way to share user-defined keywords and variables across multiple test suites. It is a .robot file that contains only Variables and Keywords sections. You import it using Resource path/to/resource.robot.

7. What is a test suite? What is a test case? 

A test suite is a collection of test cases. In Robot Framework, a file containing a Test Cases section is a test suite. A directory containing multiple such files is also considered a higher-level test suite. 

A test case is a sequence of steps (keywords) that tests a specific functionality. It starts with a name in the first column of the Test Cases section and ends before the next test case begins. 

8. How do you declare variables? What are the different variable types? 

You declare variables in the *** Variables *** section or from the command line. There are three main types: 

• Scalar Variables: They have the format ${SCALAR_NAME} and hold a single value, like a string or a number. 
• List Variables: They have the format @{LIST_NAME} and hold an ordered list of values. 
• Dictionary Variables: They have the format &{DICT_NAME} and hold key-value pairs. 

9. What is the purpose of the [Documentation] tag? 

The [Documentation] setting is used to provide a human-readable description for a test case or a user-defined keyword. This documentation is included in the final HTML report and is very useful for explaining the purpose and scope of a test. 

10. What is the [Tags] setting used for? 

The [Tags] setting is used to tag test cases with specific labels. These tags are very powerful for organizing and managing tests. You can use them to run only a subset of your tests from the command line (e.g., run only tests tagged as smoke or regression).

11. How do you run a specific test case from the command line? 

You can run a single test case using the --test (or -t) command-line option, followed by the name of the test case. The name can contain wildcards. 

Bash 
robot --test "Login with valid credentials" my_tests/login.robot 
 

12. What is SeleniumLibrary? 

SeleniumLibrary is one of the most popular external libraries for Robot Framework. It is a wrapper around the Selenium WebDriver tool and provides keywords for automating web browser interactions, such as Open Browser, Input Text, Click Button, and Get Title. 

13. What is the difference between Log and Log To Console? 

Both are BuiltIn keywords for logging. 

• Log: This keyword writes the given message to the main HTML log file generated after the test run. 
• Log To Console: This keyword prints the message directly to the console (standard output) during the test execution. This is useful for seeing real-time progress. 

14. How do you handle waits in Robot Framework? 

Waits are crucial for handling dynamic web pages. SeleniumLibrary provides several ways to wait: 

• Implicit Wait: Set once per session, it tells WebDriver to wait for a certain amount of time before throwing an error if an element is not found. 
• Explicit Waits: These are keywords that wait for a specific condition to be met, such as Wait Until Page Contains Element or Wait Until Element Is Visible. This is the preferred method as it makes tests more reliable.

15. What are arguments in a keyword? 

Arguments are values that are passed to a keyword to control its behavior. For example, in the keyword Input Text css=input#username myuser, the locator css=input#username and the text myuser are both arguments. User-defined keywords can also be designed to accept arguments. 

16. What are the different file formats that Robot Framework supports for test data? 

Robot Framework is flexible with the file formats it can parse. The most common and recommended format is the plain text file with the .robot extension. It also supports files with .txt. For developers who prefer a more structured, tabular format, it can parse Tab-Separated Values (TSV) files with a .tsv extension. The framework's parser is space-and-pipe separated, making the plain text format very readable. 

17. What is the purpose of the log.html and report.html files? 

After a test run, Robot Framework generates both a log and a report file, and they serve different purposes. 

• log.html: This is a detailed, fine-grained log of the entire test execution. It records every keyword that was run, its arguments, its status (pass/fail), and any messages that were logged. It is the primary tool for debugging failing test cases. 
• report.html: This is a high-level summary of the test results. It provides statistics, such as the total number of tests passed and failed, and organizes the results by suite and by tags. It is meant for stakeholders and managers who need a quick overview of the test run's outcome. 

18. How do you write a simple "Hello World" test case in Robot Framework? 

A "Hello World" test case is a great way to verify your setup. You would create a .robot file and use the BuiltIn keyword Log To Console to print a message. 

Code snippet-

*** Test Cases *** 
My First Test 
   Log To Console    Hello, World! 
 

To run this, you would navigate to the file's directory in your terminal and execute the command robot your_file_name.robot. You would then see "Hello, World!" printed on your console. 

19. What is the fundamental difference between a scalar and a list variable? 

The main difference is the amount of data they hold. 

• A scalar variable, denoted by ${...}, is designed to hold a single value. This can be a string, a number, a boolean, or any single object. 
• A list variable, denoted by @{...}, is designed to hold an ordered collection of multiple values. It is similar to a list or an array in other programming languages. You can access its items by their index. 

20. What is the basic command used to run Robot Framework tests? 

The basic command to execute tests is simply robot, followed by the path to the test suite file or directory you want to run. For example, to run a single test suite file named login_tests.robot, you would use the command: 

Bash 
robot login_tests.robot 
 

To run all the tests within a directory called my_tests, you would use: 

Bash 
robot my_tests/ 
 

These are some beginner-level Robot Framework Interview Questions. If you are comfortable with beginner one now, you are ready for intermediate one. 

Intermediate Level Robot Framework Interview Questions 

This section moves beyond the basics to cover more practical scenarios, data management, and framework design. These python robot framework interview questions and topics are common in interviews for experienced automation engineers. 

1. Explain the difference between keyword-driven, data-driven, and behavior-driven testing. 

• Keyword-Driven Testing (KDT): This is Robot Framework's native approach. Test cases are composed of high-level keywords that describe the actions to be taken. The focus is on action words. 
• Data-Driven Testing (DDT): This approach involves running the same test case multiple times with different sets of input and expected output data. Robot Framework supports this using the [Template] setting in a test case. 
• Behavior-Driven Development (BDD): This approach focuses on describing the system's behavior in a natural language format using the Gherkin syntax (Given/When/Then). While Robot Framework is not a pure BDD tool, it can be used to write BDD-style tests. 

2. How do you perform data-driven testing in Robot Framework? 

You use the [Template] setting within a test case. You define a user keyword as a template, and then you provide the data for each iteration of the test in the lines that follow. Each line represents one execution of the template with that line's data. 

Code snippet-

*** Test Cases *** 
Invalid Login Test 
  [Template]    Attempt Login With Invalid Credentials 
   # username    # password 
   invaliduser   wrongpassword 
   correctuser   wrongpassword 
   invaliduser   correctpassword

3. What are test setup and teardown? What is the difference between test setup and suite setup? 

• Setup and Teardown: These are actions that are run before and after a test or suite. 
• Test Setup/Teardown: The [Setup] keyword is run before each test case in a suite, and the [Teardown] keyword is run after each test case. This is used for actions that need to be repeated for every test, like opening a browser. 
• Suite Setup/Teardown: The Suite Setup keyword is run once before any test cases in the suite are executed, and Suite Teardown is run once after all test cases have finished. This is used for actions that only need to happen once, like setting up a database connection. 

4. How do you handle errors and exceptions in Robot Framework? 

Robot Framework provides several BuiltIn keywords for error handling: 

• Run Keyword And Expect Error: This keyword runs another keyword and expects it to fail with a specific error message. The test case passes only if the expected error occurs. 
• Run Keyword And Ignore Error: This runs a keyword and ignores any failure. The test execution continues regardless of the outcome. 
• Run Keyword And Continue On Failure: This runs a keyword, and if it fails, the failure is logged, but the test case execution continues. 

5. How do you create a custom keyword in Python? 

This is a core topic for python robot framework interview questions. 

1. Create a Python file (e.g., MyLibrary.py). 
2. Create a class with the same name as the file. 
3. Inside the class, create a public method. The method's name will become the keyword name (underscores are converted to spaces). 
4. The method can take arguments and should have a return statement if it needs to return a value. 
5. Import this Python file as a library in your .robot file's *** Settings *** section. 

Python 
# MyLibrary.py 
class MyLibrary: 
   def add_two_numbers(self, num1, num2): 
       return int(num1) + int(num2) 
 

6. What are BuiltIn keywords? Name a few important ones. 

The BuiltIn library is automatically available in Robot Framework and provides a set of generic keywords. Some of the most important ones are: 

• Should Be Equal As Strings: Compares two values as strings. 
• Run Keyword If: Executes a keyword only if a given condition is true. 
• Sleep: Pauses the test execution for a specified amount of time. 
• Create List: Creates a new list variable. 
• Set Global Variable: Creates a variable that is available across all test suites. 

7. How do you manage different test environments (e.g., staging, production)? 

The best way to manage different environments is by using variable files. You can create a separate Python or YAML file for each environment (e.g., staging.py, prod.py) that contains all the environment-specific variables, like URLs, usernames, and passwords. You can then specify which variable file to use from the command line when you run your tests. 

Bash 
robot --variablefile staging.py my_tests/ 
 

8. What is the purpose of the pabot tool? 

pabot stands for Parallel Executor for Robot Framework. It is an external tool that allows you to run your test cases in parallel. This can significantly reduce the total execution time of a large test suite by distributing the tests across multiple CPU cores or even multiple machines.

9. What is a listener interface in Robot Framework? 

A listener is a Python class that can be used to monitor the test execution in real time. It has methods that are automatically called at different points of the execution, such as start_suite, start_test, end_keyword, and log_message. Listeners are powerful tools for creating custom logging, reporting, or integrating with other systems. 

10. How do you debug a failing test case in Robot Framework? 

There are several methods for debugging: 

• Analyze the Log File: The HTML log file is the most valuable resource. It provides a step-by-step record of what happened, including error messages. 
• Use Log Keywords: Add Log or Log To Console keywords at various points in your test to print the values of variables. 
• Use Pause Execution: The Dialogs library has a keyword called Pause Execution that will stop the test and wait for you to resume it, allowing you to inspect the state of the application. 
• Set Log Level: Run the tests with a more detailed log level, like TRACE, to get very detailed information about what is happening in the background. 

11. How do you pass variables from the command line? 

You can pass variables directly from the command line using the --variable (or -v) option. This is very useful for passing dynamic values into your tests without hardcoding them. The syntax is --variable NAME:value. 

Bash 
robot --variable BROWSER:chrome --variable URL:http://example.com tests/ 
 

Inside your test, you can then access these variables as ${BROWSER} and ${URL}. 

12. What is the [Arguments] setting in a user-defined keyword? 

The [Arguments] setting is used to define the arguments that a user-defined keyword can accept. This is how you make your custom keywords flexible and reusable. You declare the variables that will hold the passed-in values. 

Code snippet- 

*** Keywords *** 
Login To Application 
  [Arguments]    ${username}    ${password} 
   Input Text     id=username    ${username} 
   Input Text     id=password    ${password} 
   Click Button   id=login-button 
 

13. How do you handle browser pop-ups or alerts with SeleniumLibrary? 

SeleniumLibrary provides several keywords for interacting with JavaScript alerts. The typical workflow is: 

1. Perform the action that triggers the alert. 
2. Use a keyword like Handle Alert to accept, dismiss, or leave the alert open. 
3. You can also use Alert Should Be Present to verify that an alert has appeared, and Input Text Into Alert if the alert is a prompt that accepts text.

 14. How do you take a screenshot on test failure? 

The SeleniumLibrary has a keyword called Register Keyword To Run On Failure. You can use this in your Suite Setup to specify that the Capture Page Screenshot keyword should be run automatically whenever any keyword fails. 

Code snippet-

*** Settings *** 
Suite Setup    Register Keyword To Run On Failure    Capture Page Screenshot 
 

This is a very powerful feature for debugging UI test failures, as it provides a visual record of the application's state at the moment of failure. 

15. What are some common libraries you have used besides SeleniumLibrary? 

This question checks the breadth of your automation experience. Some good examples to mention are: 

• RequestsLibrary: For API testing. 
• DatabaseLibrary: For connecting to databases to verify data or set up test conditions. 
• AppiumLibrary: For mobile application testing. 
• SSHLibrary: For connecting to remote machines over SSH to perform actions. 
• OperatingSystem: A BuiltIn library for interacting with the operating system (e.g., file operations). 

16. What are dictionary variables and how do you use them? 

A dictionary variable holds key-value pairs and is identified by the &{...} syntax. They are useful for storing structured data. You can access individual values by specifying the key. 

Code snippet- 

*** Variables *** 
&{USER_DATA}    name=John Doe    email=john.doe@email.com 
 
*** Test Cases *** 
Example Test 
   Log    User's name is ${USER_DATA.name} 
 

This makes your test data more organized and readable compared to using multiple scalar variables. 

17. How do you read data from an Excel file in your tests? 

Robot Framework does not have a built-in library for handling Excel files. However, you can use an external library like ExcelLibrary or DataDriver. A more flexible approach is to write a small custom Python library that uses a popular Python package like openpyxl or pandas to read the Excel file and return the data as a list of dictionaries, which can then be easily used in your test cases. 

Advanced Level Robot Framework Interview Questions 

This section includes advanced design, architecture, and customization topics. These robot framework interview questions are designed to test your deep understanding and experience with building complex automation solutions. 

1. Explain the Page Object Model (POM) and how you would implement it in Robot Framework. 

The Page Object Model is a design pattern used to create a more maintainable and scalable automation framework. 

• Concept: You create a separate class (or resource file in Robot Framework) for each page or major component of your application. This class is responsible for containing all the locators (element identifiers) and the keywords (methods) that interact with that specific page. 
• Implementation: Your test cases should not contain any locators or low-level Selenium keywords. Instead, they should call the high-level keywords from the appropriate page object file. This separates the test logic from the implementation details, so if the UI changes, you only need to update the page object file, not every single test case. 

2. What is the difference between a static and a dynamic library API? 

This is an advanced question about creating custom libraries in Python. 

• Static API: This is the standard way. You define methods in a Python class, and the names of the methods directly map to the keyword names. Robot Framework inspects the class at the start to determine what keywords are available. 
• Dynamic API: This is a more flexible approach. The library class does not have methods that directly match the keywords. Instead, it has a special method called run_keyword. Robot Framework will call this method for any keyword it cannot find, passing the keyword name and its arguments. The run_keyword method is then responsible for executing the correct logic. This is useful for creating libraries with a very large or changing set of keywords.

3. How does Robot Framework handle remote execution? 

Robot Framework supports remote execution through its Remote Library. This is a special library that acts as a proxy between Robot Framework and a test library running on a different machine. The remote library server can be implemented in any language, which means you can even run keywords that are written in Java or .NET. This is a powerful feature for distributed testing. 

4. What are some limitations of Robot Framework and how would you work around them? 

While powerful, Robot Framework has some limitations: 

• Complex Logic: Writing very complex programming logic (nested loops, complex conditions) can be clumsy using the keyword syntax. Workaround: Implement the complex logic in a custom Python library and expose it as a single, powerful keyword. 
• Performance: Robot Framework has some overhead due to its Python-based execution. Workaround: For performance-critical tasks, use pabot for parallel execution or write performance-critical parts in a lower-level language. 
• IDE Support: While there are good plugins for VS Code and other editors, the IDE support is not as mature as it is for traditional programming languages.

5. How can you perform API testing using Robot Framework? 

You can perform API testing by using the RequestsLibrary. This is a very popular external library that is a wrapper around the Python requests library. It provides a clean set of keywords for making HTTP requests (GET, POST, PUT, DELETE), handling headers, and validating the JSON or XML responses. 

6. How would you design a scalable test automation framework? 

A scalable framework should have: 

• A clear, organized folder structure that separates test suites, resource files, page objects, and custom libraries. 
• Implementation of the Page Object Model to keep UI interactions separate from test logic. 
• A system for managing test data, such as using external Excel or CSV files. 
• The use of variable files to manage different environments. 
• Integration with a CI/CD pipeline for automated execution. 
• The use of tags for flexible test selection and reporting. 

7. How can you extend Robot Framework's reporting capabilities? 

You can extend reporting in a few ways: 

• Using a Listener: Create a custom listener in Python to process the results in real time and send them to another system, like a test management tool or a database. 
• Using rebot: The rebot tool can be used to combine and post-process the output.xml files from multiple test runs. You can use it to create aggregated reports. 
• Parsing output.xml: The output.xml file contains all the information about the test run in a structured format. You can write your own scripts to parse this file and generate any kind of custom report you need. 

8. How would you secure sensitive data like passwords in your Robot Framework project? 

Hardcoding sensitive data directly in test cases is a bad practice. Better approaches include: 

• Variable Files: Store the credentials in a separate Python variable file that is excluded from version control (e.g., via .gitignore). 
• Environment Variables: Store the credentials as environment variables on the execution machine or in a CI/CD tool's secrets management system. Your tests can then read these variables at runtime using the %{...} syntax or a custom Python library. 
• Vaults: For the highest level of security, use a dedicated secrets management tool like HashiCorp Vault or AWS Secrets Manager and create a custom library to fetch the credentials at the start of the test run. 

9. Explain how to handle shadow DOM elements in web automation. 

By default, Selenium cannot directly interact with elements inside a shadow DOM. To handle this, you need to use JavaScript. The process involves: 

1. Using the Execute Javascript keyword from SeleniumLibrary. 
2. Writing a JavaScript snippet to first query the shadow host element. 
3. From the host element, access its .shadowRoot property. 
4. From the shadow root, you can then use standard query selectors (like querySelector) to find the element you need to interact with. 

10. What is the purpose of the --flattenkeywords option? 

The --flattenkeywords option is a command-line tool used with rebot to modify the structure of the output log file. It can flatten the keyword hierarchy by using FOR, IF, or user-keyword structures. For example, using --flattenkeywords FOR, all keywords inside a FOR loop will be shown at the same nesting level as the loop itself in the log. This can sometimes make log files easier to read by reducing deep nesting. 

11. How can you create a library that maintains a state? 

You can create a stateful library by defining it as a Python class. When Robot Framework imports a library, it creates one instance of that class, which then persists for the entire duration of the test suite. You can store state within the class instance using instance attributes (e.g., self.browser_session or self.api_token). This is the standard way to manage things like a persistent browser session or a database connection across multiple keywords. 

12. What is the Pre-run Modifier interface? 

A Pre-run Modifier is an advanced feature that allows you to programmatically alter the test suite structure before execution begins. You can create a Python script that acts as a modifier to add or remove test cases, change tags, or modify keywords on the fly. This is useful for dynamically generating tests based on external data or for making last-minute adjustments to a test plan. 

13. How would you integrate Robot Framework with a BDD tool like Gherkin? 

While Robot Framework is keyword-driven, it can be adapted for BDD. One common approach is to use the robotframework-behave library or a similar tool. This allows you to write your feature files using the standard Gherkin syntax (Given-When-Then). You then write Python functions that act as "step definitions" to link the Gherkin steps to Robot Framework keywords. This combines the readability of BDD with the power of Robot Framework's keyword ecosystem. 

14. How would you test a desktop application using Robot Framework? 

To automate desktop applications, you need a library that can interact with the operating system's UI elements. Popular choices include: 

• RPA.Desktop.Windows (from the RPA Framework): A modern library for automating Windows applications. 
• AutoItLibrary: A library that integrates with the AutoIt tool for Windows GUI automation. 
• ImageHorizonLibrary: A library that uses image recognition to find and interact with UI elements, making it platform-independent but potentially less reliable.

What is Robot Framework and Why is it Popular? 

Robot Framework is a generic, open-source automation framework. It can be used for test automation and robotic process automation (RPA). It was initially developed at Nokia Networks and is now supported by the Robot Framework Foundation. 

Its popularity comes from a few key features: 

• Keyword-Driven Approach: Tests are created using keywords that are written in a human-readable format. This makes the tests easy to understand, even for people who are not programmers, like business analysts or manual testers. 
• Simple, Tabular Syntax: Test cases are written in simple text files using a tabular format. This clean syntax makes test creation and maintenance straightforward. 
• High Extensibility: Robot Framework has a massive ecosystem of external libraries. You can use pre-built libraries for web testing (SeleniumLibrary), API testing (RequestsLibrary), mobile testing (AppiumLibrary), and more. You can also create your own custom libraries using Python. 
• Detailed Reports and Logs: After a test run, Robot Framework automatically generates a detailed HTML report and log file. These reports are very clear, providing a high-level overview and a deep dive into every step of the test execution. 

 Conclusion 

Preparing for these robot framework interview questions will give you a solid foundation to demonstrate your skills as a test automation engineer. Remember that interviewers are looking for more than just correct answers; they want to see your problem-solving process and your understanding of automation principles. The best way to solidify this knowledge is to build projects, experiment with the framework's features, and apply these concepts to real-world challenges.
