The correct answer is: B. Regression testing ✅ Here's why: Regression testing is performed after changes (such as bug fixes, enhancements, or updates) have been made to an existing system to ensure that the previously working functionality still works as expected. It helps detect if any new code has unintentionally broken existing features.
-Smoke Test runs after the code is compiled into a build and before it is deployed and released. These tests confirm that the main features are working before detailed tests run. -Regression Test confirms that the code change did not affect any existing functionality. -Unit Test measures the smallest piece of functionality in software. Each component or unit is tested to ensure it works. -User Acceptance Testing (UAT) evaluates the final outputs against specifications. If this test passes, you can safely assume a user will accept the product. Directly pulled from Certmaster.
