What is Robot in Software Testing?

Published in Test Automation 3 mins read

A "robot" in the context of software testing most commonly refers to Robot Framework, an open-source automation framework widely used for test automation.

Robot Framework Explained

Robot Framework is a generic, open-source automation framework. It's designed for acceptance testing, acceptance test-driven development (ATDD), and robotic process automation (RPA). Key characteristics include:

  • Keyword-Driven Approach: Robot Framework uses a keyword-driven testing approach. This means tests are written using descriptive keywords rather than complex code, making them more readable and maintainable.

  • Tabular Syntax: Test cases are typically written in a tabular format (e.g., using plain text, HTML, or reStructuredText files). This format improves readability and allows for easy collaboration.

  • Extensible: Robot Framework is highly extensible. It can be extended with custom test libraries implemented in Python, Java, and other languages. This allows you to adapt the framework to your specific testing needs.

  • Versatile: While often associated with acceptance testing, Robot Framework can also be used for other types of testing, including:

    • Integration testing
    • System testing
    • Even some forms of unit testing.

Key Benefits of Using Robot Framework

  • Ease of Use: The keyword-driven and tabular syntax make it easy to write and understand test cases, even for individuals with limited programming experience.

  • Reusability: Keywords can be reused across multiple test cases, reducing redundancy and improving maintainability.

  • Reporting: Robot Framework generates detailed and informative HTML reports, providing a clear overview of test results.

  • Integration: It integrates well with other tools and technologies, such as Selenium (for web testing), Appium (for mobile testing), and various continuous integration/continuous delivery (CI/CD) systems.

Example of a Robot Framework Test Case

***Settings***
Library           SeleniumLibrary

***Variables***
${URL}            https://www.example.com
${BROWSER}        chrome

***Test Cases***
Verify Website Title
    Open Browser          ${URL}          ${BROWSER}
    Title Should Be       Example Domain
    Close Browser

In this example:

  • ***Settings***, ***Variables***, and ***Test Cases*** are sections that define the test environment, variables, and the test itself.
  • Open Browser, Title Should Be, and Close Browser are keywords that represent specific actions.

Other Uses of the Term "Robot" in Testing

While Robot Framework is the most common association, the term "robot" in testing can also refer to:

  • Test Automation Bots: General term for automated processes or scripts that perform testing tasks.
  • Automated Input Generation: Programs that generate input data for testing purposes, mimicking human interaction or exploring edge cases.

In conclusion, when someone asks about "robot" in software testing, they most likely mean Robot Framework, a popular open-source automation framework. It provides a user-friendly, keyword-driven approach to test automation, making it a valuable tool for teams looking to improve their testing processes.
