Explain the usage of the BuiltIn library in Robot Framework.

The BuiltIn library in Robot Framework is like a toolbox full of essential tools that you'll use constantly. It's automatically included in every Robot Framework test suite, so you don't need to explicitly import it. Think of it as the foundation upon which you build your tests.

Here's a breakdown of its key purposes and some commonly used keywords:

Purpose:

The BuiltIn library provides a set of generic keywords that are frequently needed in test automation. These keywords cover a wide range of tasks, including:

  • Verifications: Checking conditions and making assertions (e.g., "Should Be Equal," "Should Contain").
  • Conversions: Converting data between different types (e.g., "Convert To Integer," "Convert To String").
  • Flow control: Controlling the execution flow of your tests (e.g., "Run Keyword If," "Exit For Loop").
  • Variable manipulation: Setting and getting variables (e.g., "Set Variable," "Get Variable Value").
  • Logging: Logging messages to the console and report files (e.g., "Log," "Log To Console").
  • Waiting: Pausing test execution for a specified time (e.g., "Sleep").
  • Miscellaneous: Other useful utilities (e.g., "Evaluate," "Fail").
