This GitHub Action requires writing the tests in Pull Requests, by requesting changes and posting a comment if tests are missing.

To install it, copy and paste the following snippet into your .github/workflows/require-tests.yml file.

name: 'Require tests if source code is changed'

on:
  pull_request_target:
    types: [opened]

jobs:
  check:
    runs-on: ubuntu-latest
    steps:
      - uses: infection/[email protected]
        with:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

Default values are:

comment: 'Could you please add tests to make sure this change works as expected?',
fileExtensions: '.php,.ts,.js,.c,.cs,.cpp,.rb,.java'
testDir: 'tests'
testPattern: ''

where

• comment - a text that bot will post when it won't find tests in the PR
• fileExtensions - extensions of the files that should be treated as a source code. Bot will do nothing if you just updating README.md because usually no tests are required to cover such change.
• testDir - folder, where tests are located. Make sure to set it correctly, otherwise bot will not be able to understand whether the test file was added or not.
• testPattern - a shell glob pattern that should match test files. For example, you can set it to testPattern: *_test.go and Bot will be able to understand, that added test has this pattern instead of located in testDir. testDir and testPattern are alternatives, however can be used together.

How to override? You can configure the action by overriding any of the settings listed above.

- name: Require tests if source code is changed
  uses: infection/tests-checker-action@v1
  with:
    fileExtensions: '.ts,.js'
    testDir: '__tests__'
    GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

First, you'll need to have a reasonably modern version of node handy. This won't work with versions older than 9, for instance.

Install the dependencies

$ npm install

Build the typescript and package it for distribution

$ npm run build && npm run package

Run the tests ✔️

$ npm test

 PASS  ./index.test.js
  ✓ test runs (95ms)

...

Actions are run from GitHub repos so we will checkin the packed dist folder.

Then run ncc and push the results:

$ npm run package
$ git add dist
$ git commit -a -m "prod dependencies"
$ git push origin releases/v1

Note: We recommend using the --license option for ncc, which will create a license file for all of the production node modules used in your project.

Your action is now published! 🚀
