如何创建 GitHub Action 以使用 Yarn 运行 Jest 测试？

Question

I use Yarn to run my Jest tests.

package.json

{
  "scripts": {
    "test": "jest"
  }
}

yarn test

I want to create a GitHub action to run my tests when I merge commits in GitHub. The Node Starter Workflow runs tests with NPM. But I want to run them with Yarn.

How do I create an action to run my tests?

Answer 1

Use the Node Starter Workflow but replace the NPM portion with Yarn commands. For example:

name: Node CI

on: [push]

jobs:
  build:

    runs-on: ubuntu-latest

    strategy:
      matrix:
        node-version: [10.x, 12.x]

    steps:
    - uses: actions/checkout@v2
    - name: Use Node.js ${{ matrix.node-version }}
      uses: actions/setup-node@v1
      with:
        node-version: ${{ matrix.node-version }}
    - run: yarn install
    - run: yarn test
