Helm Unittest

Helm Unittest is a code we adopt in the garden.

Blurb

BDD styled unit test framework for Kubernetes Helm charts as a Helm plugin. - helm-unittest/helm-unittest

Summary

Chart authors encode scenarios as test files under tests/ (or similar): set values, render templates, and compare output to expected YAML or snapshots. This is far faster and more deterministic than only testing in a live cluster, and it documents expected behavior for reviewers.

Details

• Workflow: install the plugin (helm plugin install https://github.com/helm-unittest/helm-unittest); run helm unittest in the chart directory in CI.
• Assertions: document presence, equals, match regex, snapshot files, and suite-level setup/teardown for values files.
• Fit: essential when you ship Helm Chart artifacts to customers or run many value permutations (dev/stage/prod).
• Limits: tests template output, not cluster behavior, pair with integration tests for admission, CRDs, and hooks.
• Note: superseded the earlier quintush/helm-unittest fork; use the helm-unittest org repository.
