After new capabilities were deployed in a system, issues with preexisting capabilities were reported. Which of the following testing cycles should be used to prevent this issue?
Technically, the right answer is regression testing "specifically designed to ensure that new code changes haven't broken any existing functionalities". Stupid question. Maybe "B"?
A unit test measures the smallest piece of functionality in software. Each
component or unit is tested to ensure it works. Unit tests work well with modular
coding approaches where developers reuse code. Unit tests run as the developer
writes code and are highly valuable. This is helpful because it finds issues right away
and allows the developer to fix them while writing the code.
Some of the useful testing cycles that fit this scenario:
- Regression Testing
- Integration Testing
- User acceptance testing
- System testing
Only D showed up in the options, so the best fit is D
