在 Windows 环境下的 GithubActions 中运行 cypress

Question

我想在 github 操作中运行我的 cypress 测试。应该对 Firefox、chrome 和 edge 进行测试。 Cypress 支持所有这些：https://github.com/cypress-io/github-action#browser

虽然 firefox 和 chrome 运行良好，但边缘设置并不是那么完美。这是因为边缘浏览器在 github 操作中运行在 Windows 系统上。

这是构建 next.js 应用程序的 yml 文件，然后使用边缘浏览器对其进行测试：

build:
  runs-on: ubuntu-latest
  steps:
    - name: Checkout code
      uses: actions/checkout@v2

    - uses: actions/setup-node@v2-beta
      with:
        node-version: "12"

    - name: Get yarn cache directory path
      id: yarn-cache-dir-path
      run: echo "::set-output name=dir::$(yarn cache dir)"

    - name: Cache node_modules
      id: yarn-cache
      uses: actions/cache@v2
      with:
        path: ${{ steps.yarn-cache-dir-path.outputs.dir }}
        key: ${{ runner.os }}-yarn-${{ hashFiles('**/yarn.lock') }}

    - name: Install Dependencies
      run: yarn

    - name: Build
      run: yarn build

    - name: Upload next build
      uses: actions/upload-artifact@v2
      with:
        name: dist
        path: .next

e2e-test-edge:
  needs: build
  runs-on: windows-latest
  strategy:
    matrix:
      node: [12]

  steps:
    - name: Checkout code
      uses: actions/checkout@v2

    - name: Download next build from previous step
      uses: actions/download-artifact@v2
      with:
        name: dist
        path: .next

    - name: Cache Cypress binary
      uses: actions/cache@v2
      with:
        path: ~/.cache/Cypress
        key: cypress-${{ runner.os }}-cypress-${{ github.ref }}-${{ hashFiles('**/package.json') }}

    - name: Get yarn cache directory path
      id: yarn-cache-dir-path
      run: echo "::set-output name=dir::$(yarn cache dir)"

    - name: Cache node_modules
      id: yarn-cache
      uses: actions/cache@v2
      with:
        path: ${{ steps.yarn-cache-dir-path.outputs.dir }}
        key: ${{ runner.os }}-yarn-${{ hashFiles('**/yarn.lock') }}

    - name: Install Dependencies
      run: yarn install --frozen-lockfile

    - name: Verify Cypress
      env:
        # make sure every Cypress install prints minimal information
        CI: 1
      # print Cypress and OS info
      run: |
        npx cypress verify
        npx cypress info
        npx cypress version
        npx cypress version --component package
        npx cypress version --component binary
        npx cypress version --component electron
        npx cypress version --component node

    - name: Cypress edge browser tests
      uses: cypress-io/github-action@v2
      with:
        browser: edge
        start: yarn start

    - uses: actions/upload-artifact@v2
      if: failure()
      with:
        name: edge-cypress-screenshots
        path: cypress/screenshots
    # Test run video was always captured, so this action uses "always()" condition
    - uses: actions/upload-artifact@v2
      if: always()
      with:
        name: edge-cypress-videos
        path: cypress/videos

因此，如果此管道在 github 操作中运行，则一切正常。缓存部分被跳过，因为这是第一次构建，所以没有缓存键匹配。 Deps 也安装无误，Cypress verify 部分对我来说也很好：

Run npx cypress verify
  npx cypress verify
  npx cypress info
  npx cypress version
  npx cypress version --component package
  npx cypress version --component binary
  npx cypress version --component electron
  npx cypress version --component node
  shell: C:\Program Files\PowerShell\7\pwsh.EXE -command ". '{0}'"
  env:
    CI: 1

但随后到达Cypress edge browser tests 部分并出现以下错误：

    browser: edge
    start: yarn start
    record: false
    config-file: cypress.json

No cached binary versions were found.
C:\windows\system32\cmd.exe /D /S /C ""C:\Program Files\nodejs\npx.cmd" cypress verify"
The cypress npm package is installed, but the Cypress binary is missing.

We expected the binary to be installed here: C:\Users\runneradmin\.cache\Cypress\6.0.0\Cypress\Cypress.exe

Reasons it may be missing:

- You're caching 'node_modules' but are not caching this path: C:\Users\runneradmin\AppData\Local\Cypress\Cache
- You ran 'npm install' at an earlier build step but did not persist: C:\Users\runneradmin\AppData\Local\Cypress\Cache

Properly caching the binary will fix this error and avoid downloading and unzipping Cypress.

Alternatively, you can run 'cypress install' to download the binary again.

Platform: win32 (10.0.17763)
Cypress Version: 6.0.0
Error: The process 'C:\Program Files\nodejs\npx.cmd' failed with exit code 1

我尝试了错误消息中的所有内容：

• 在失败部分之前执行cypress install
• 将缓存目录更改为绝对路径C:\Users\runneradmin\.cache\Cypress

我也没有找到 cypress 和 windows 结合的 github action yml 的例子。可能是我太笨了，看不懂windows机器。

Answer 1

您正在缓存“node_modules”，但未缓存此路径：C:\Users\runneradmin\AppData\Local\Cypress\Cache

即使我没有使用 actions/cache 缓存 npm 模块，我也遇到了同样的错误。我尝试了actions/cache，但仍然遇到同样的错误。

我通过做两件事解决了这个问题：

1- 在actions/cache中指定赛普拉斯二进制缓存路径

2- 在cypress-io/github-action中设置CYPRESS_CACHE_FOLDER
