A software developer checked in new code and pushed it into the remote code repository. Which of the following activities is most likely to happen immediately after the push? (Wentz QOTD)
A. Unit testing
B. Integration testing
C. Regression testing
D. Management acceptance of residual risk
Kindly be reminded that the suggested answer is for your reference only. It doesn’t matter whether you have the right or wrong answer. What really matters is your reasoning process and justifications.
My suggested answer is B. Integration testing.
Unit Testing
Unit testing is both a test and development instrument. Modern software developers usually develop a unit test before the feature code is done, aka test-driven development (TDD) approach. In other words, every software feature comes with a set of unit tests to ensure it functions properly.
Integration Testing
Nowadays, software developers are writing code on their desktops or laptops where a local code repository resides. They “commit” or “check in” codes into the local code repository first. If local codes are built and tested without problems, they are pushed to the remote central code repository for integration. Continuous integration (CI) means the remote server starts the server build automatically once the CI criteria are met, e.g., whenever new codes are checked in or it starts building periodically (e.g., nightly build). If the server build succeeds, it starts (integration) testing automatically. Unit tests and UI tests can be done without user intervention, e.g., using Selenium to support the automated end-to-end (e2e) web UI tests.
Regression Testing
If the server build fails, the central server for the remote code repository will notify developers of errors. Developers making bugs or breaking the build have to fix them and repeat the process until no error occurs. It’s a process of regression testing.
