What term is used for the testing intended to uncover new bugs after changes in software?

• A. Nonregression testing
• B. Evolution testing
• C. Smoke testing
• D. Regression testing

Answer: (D)

The term that describes the testing intended to uncover new bugs after changes in software is regression testing. This type of testing ensures that recent code changes have not adversely affected the existing functionality of the software. When modifications are made—such as bug fixes, enhancements, or new features—regression testing is conducted to verify that the application continues to perform as expected. Regression tests typically focus on areas of the software that may have been influenced by those changes. This is crucial in software development, as it helps maintain the integrity of the application and ensures that previously working features remain functional. Other testing types in the options presented have distinct purposes. Nonregression testing, while not a standard term, generally implies testing that does not focus on verifying previously existing features but rather on new functionalities. Evolution testing is not widely recognized in the industry as a term associated specifically with software testing practices. Smoke testing refers to a preliminary test to check the basic functionality of an application, often before more in-depth testing is performed; it does not specifically address the detection of new bugs resulting from changes. Thus, regression testing is the most appropriate term for this scenario.
