A development team uses Jenkins to manage build jobs. They observe that merges from feature branches often lead to breakage in the main line. Which strategy addresses this problem by verifying changes before integrating them?
Periodically integrate all updates into the main line in bulk near the end of the release cycle
Allow developers to push without environment checks to accelerate the release process
Adopt a practice of manual code merges after minimal linting to reduce complexity
Run automated checks on proposed changes, then link successful results to the main line merge process
Integrating automated testing prior to merging promotes stability in the main line. Testing on feature branches detects integration issues early. Manual merges without thorough tests can introduce errors that are discovered late. Merging large sets of changes together makes identifying the source of failures difficult. Relying on local tests alone ignores environment-specific aspects.
