Jest Github Action

Main features:

• Add status checks with code annotations to your pull requests
• Comment your pull requests with code coverage table (if tests succeeded)

Coverage example

Usage

You can now consume the action by referencing the v1 branch

uses: mattallty/jest-github-action@v1
env:
  GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

Overriding the test command

By default, this action will execute npm test to run your tests. You can change this behavior by providing a custom test-command like this:

uses: mattallty/jest-github-action@v1
env:
  GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
with:
  # this is just an example, this could be any command that will trigger jest
  test-command: "yarn test"

Running tests only on changed files

uses: mattallty/jest-github-action@v1
env:
  GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
with:
  # Runs tests related to the changes since the base branch of your pull request
  # Default to false if not set
  changes-only: true

Silencing the code coverage comment

uses: mattallty/jest-github-action@v1
env:
  GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
with:
  # To avoid reporting code coverage, set this variable to false
  coverage-comment: false

Running tests in a subdirectory

For running tests in folders other than root, supply a working-directory.

uses: mattallty/jest-github-action@v1
env:
  GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
with:
  working-directory: "frontend"
