stefanoeb / jest-action

Wraps and install Jest test runner in a github action.

⚠️⚠️⚠️ You don't need this action ⚠️⚠️⚠️

Github Actions have everything that you need to run your jest tests, to do that simply use the run commands like so:

name: CI
on: push
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v2
    - name: Install modules
      run: yarn
    - name: Run tests
      run: yarn test

---

This action executes Jest test runner without any previous action/build step or Docker required.

Prerequisites

Jest

You must have the Jest running locally for the action to execute. More info on the Jest getting started guide

Usage

Add to your main.yml file or create a new file named .github/workflows/test.yml and add:

name: Tests

on: [push]

jobs:
  build:

    runs-on: ubuntu-latest

    steps:
    - uses: actions/checkout@v1
    - name: Run Jest
      uses: stefanoeb/[email protected]

You can also pass custom args to jest through the with: parameter:

name: Tests

on: [push]

jobs:
  build:

    runs-on: ubuntu-latest

    steps:
    - uses: actions/checkout@v1
    - name: Run Jest
      uses: stefanoeb/[email protected]
      with:
        jestArgs: path/to/my.test.js

If there is no previous step installing the necessary modules, this action will execute a yarn install or npm install automatically.

Not sure if this is related to your action or something I've setup wrong. Any help would be appreciated.

How I am doing my tests (without a Dockerfile)

Not sure if this will help, but I have a simplified way of doing it (doesn't rely on docker at all)

name: Tests

on: [push]

jobs:
  unittests:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v1
    - name: Run Tests
      run: |
        npm install 
        npm test

Upgrade node version

When using this action, the jest tests are failing now in CI after I upgraded to webpacker 5 with error like...
@rails/[email protected]: The engine "node" is incompatible with this module. Expected version ">=10.17.0". Got "10.14.1"

Can you please upgrade the node version in your docker file by changing this: FROM node:10.14.2-alpine

Subdirectory?

Sorry I'm new to github actions, but is it possible to run this action inside a subdirectory like /express or /client ?
