Contributing

Whenever making a change to a chart, you must update the version:

• Update <chartname>/CHANGELOG.md
• Update <chartname>/Chart.yaml with the new version number from CHANGELOG.md
• Run pre-commit hook to automatically update the docs

  pre-commit install && pre-commit run -a
  

Testing

Unit tests are integrated into the pull request workflow, but can also be run locally.

# Remove old versions of the plugin
helm plugin uninstall unittest

helm plugin install https://github.com/helm-unittest/helm-unittest.git
helm unittest ./charts/standard-application-stack --strict

This repo makes use of snapshot testing to detect unexpected changes to manifests. When you run the tests after making a change that effects existing manifests, you will see a lot of test errors complaining about differences between what the chart renders and the snapshots. Review the changes and, if you're satisfied, update the snapshots by rerunning the tests with the --update-snapshot flag:

helm unittest ./charts/standard-application-stack --strict --update-snapshot

When adding new tests, please be sure to always add a matchSnapshot assertion:

- it: does something
  asserts:
    - matchSnapshot: {} # <-- Make sure to always add this after `asserts`!
