      debugging?
      A It's a debugging technique for large systems. Correct Answer Incorrect Answer
      B It's a method for testing individual components (units) of code in isolation, which can help prevent bugs and make debugging easier when they do occur. Correct Answer Incorrect Answer

      D It's a type of performance testing. Correct Answer Incorrect Answer
      E It's an alternative to using a debugger. Correct Answer Incorrect Answer

      Solution

      Unit testing involves writing small, isolated tests for individual functions, methods, or classes. By ensuring each unit works correctly, it helps catch bugs early in the development cycle, making the overall system more robust and simplifying debugging when integration issues or more complex bugs arise.
