What is typically viewed as an extension of the coding process____________________?
Show answer Hide answer
Answer: B. Unit testing
Explanation
Unit testing is performed immediately after writing code by the developer themselves. It verifies the smallest testable parts of an application functioning in isolation. This close temporal relationship makes unit testing an organic extension of coding. Developers write unit tests alongside application code to validate individual functions or methods. Automated testing frameworks execute these tests rapidly to catch errors at inception. Test driven development mandates writing unit tests even before implementing the actual code.
Software engineers write unit tests for utility functions before moving to integration tasks. Continuous integration servers run unit test suites automatically upon every code commit. Catching bugs during unit testing significantly reduces the cost of later debugging. Integration testing occurs after unit testing when combining multiple distinct software modules. Completion of testing marks the final phase of the verification lifecycle entirely. Regression testing validates existing features after implementing subsequent changes or patches.
