Example usage in a workflow YAML file:

Here are a few examples of workflow YAML files for the Kani Github Action:

Example 1: Default configuration

Default config which uses the latest version of Kani to run cargo-kani on project in current directory.

jobs:
  kani:
    runs-on: ubuntu-latest
    steps:
      - name: Run Kani
        uses: model-checking/kani-github-action@v1

Example 2: Use pinned version of Kani

Use a specific version of Kani, version 0.35.0, to run cargo-kani on a project.

jobs:
  kani:
    runs-on: ubuntu-latest
    steps:
      - name: Run Kani
        uses: model-checking/kani-github-action@v1
        with:
          kani-version: '0.35.0'
          command: 'cargo-kani'
          working-directory: './path/to/project'

Example 3: Run Kani with args

Use latest version of Kani, to run cargo-kani --tests on a project with propproof harnesses.

    runs-on: ubuntu-latest
    steps:
      - name: Run Kani
        uses: model-checking/kani-github-action@v1
