helmtest

helmtest

Generate/use golden test files to ensure helm charts are valid.

Update

Use UPDATE=true go test -count=1 ./... to update the golden test files. Note, -count=1 is usually required.

Default tests

The test code picks up all Helm steps configured in this repo by iterating over the ../../topology.yaml file. It then generates fixtures using the default configuration referenced in the settings.yaml.

Tests with custom data

If you want to test certain template features, you can create a custom test by adding a helmtest_...yaml file, i.e.:

values: ../../values-mgmt.yaml
name: helmtest-kusto-enabled
namespace: arobit
testData:
  kusto:
    enabled: true
    environmentName: test
    ingestionUrl: http://foobar

This file is located in the arobit chart directory, in the subfolder testdata. It overrides the kusto setting and enables it. This would usually make sense only for MSFT specific environments and enables reviewing template output for all possible scenarios.

Regex

You can configure static replacements in the settings.yaml, as such:

Replace:
  - Regex: 'sha256.[a-fA-F0-9]{64}'
    Replacement: 'sha256:1234567890'

these Replacements will be applied on the generated manifest before writing them to disk/verifying them.
