This project's repo uses diff-cov-lint itself. You might want to check .gitlab-ci.yml for full configuration.
The scenario is following:
- Run tests on each push (test job)
- Calculate diff coverage and produce diff pylint reports for merge requests (code_quality_diff job)
- Get coverage and pylint report on full code on master and tags or manually on any push. (code_quality_full job)
test: stage: test script: - pytest --cov=your_source_folder --cov-report xml tests # run pytest and produce xml report artifacts: paths: - coverage.xml # save xml report to use it in further jobs only: - tags # tags and branches are default values of "only", so preserve them - branches - merge_requests # add merge_requests since code_quality_diff job will use artifacts of this job
Diff code quality job:
code_quality_diff: stage: code_quality_diff script: - git fetch -a # fetch all branches to calculate diff - pip install diff-cov-lint # install diff-cov-lint - pylint --exit-zero diff_cov_lint > pylint_output.txt # get pylint report. --exit-zero needed for job not to fail if pylint give score less than 10. - diff-cov-lint origin/$CI_MERGE_REQUEST_TARGET_BRANCH_NAME origin/$CI_MERGE_REQUEST_SOURCE_BRANCH_NAME --cov_report coverage.xml --lint_report pylint_output.txt # run diff-cov-lint on diff between target branch and source branch. coverage.xml is used from the artifact. only: - merge_requests
Full code quality job:
code_quality_full: stage: code_quality_full script: - pytest --cov=your_source_folder tests # simply run pytest with coverage and pylint as usual - pylint --exit-zero diff_cov_lint rules: - if: '$CI_COMMIT_REF_NAME == "master"' - if: $CI_MERGE_REQUEST_ID when: never #otherwise this job will stuck for merge requests - when: manual # use manual to make this job optional.
