Composite action that installs the latest version of Helm 3 through helm's install script, the helm-unittest plugin, and then executes chart unit tests for the specified charts or for every chart in the repository.

There are two optional inputs for this action:

What flags to pass to the helm unittest command. By default this is -3 --color, which mean the charts will be interpreted as Helm v3 charts (as opposed to v2), and the output will always contain colors.

• Default: "-3 --color"
• Required: no

Paths to the charts that will be tested by the action, separated by spaces. If empty, every directory containing a Chart.yaml file is assumed to be a chart and will be tested.

• Default: ""
• Required: no

The following example is of a CI workflow for a repository containing Helm charts. It will run helm dependency update on each chart and subsequently helm unittest -3 --color for all of them at once.

name: CI

on: pull_request

jobs:
  unittest:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - uses: d3adb5/helm-unittest-action@v1

Note that after the action itself, Helm is installed, so you can run additional Helm commands in the same action:

name: CI

on: pull_request

jobs:
  unittest:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - uses: d3adb5/helm-unittest-action@v1
      - run: helm lint my-chart
