Worked on enhancing test coverage for the Docker Image History API within the thaJeztah/docker repository by migrating legacy CLI-based tests to a modern integration test framework. This involved removing outdated test suites and implementing a dedicated integration test file to verify the accuracy of history data for built images. The approach improved test reliability and reduced continuous integration noise, streamlining the validation process for image history changes. Utilized Go for test development, leveraging Docker and Docker API expertise alongside integration testing skills. The work focused on ensuring maintainable, robust testing infrastructure to support ongoing development and accurate verification of image history functionality.
