Implementing continuous testing (CT) is a crucial advancement in the software development process, enhancing both speed and quality by integrating automated tests into the continuous integration (CI) pipeline. This approach focuses on applying the fail-fast principle, where every code change is tested with various layers of automated tests, providing rapid feedback on the product's quality. Utilizing GitHub Actions, which offers flexibility and ease of use, developers can streamline the CI/CT process by centralizing application, tests, and workflow configurations within the repository. The process involves setting up a GitHub Actions workflow for unit tests, adding code coverage reports, and extending CT with API, end-to-end, and performance testing. Emphasizing the five DevOps principles—culture, automation, lean, measurement, and sharing—ensures effective CT implementation, fostering a collaborative environment where testing becomes a fundamental part of the team's workflow.
