Circle Ci - 启动反应服务器并通过赛普拉斯进行测试

Question

我运行在用 cirleci 脚本启动的服务器上安装 cypress。虽然柏树无法找到我刚启动的本地服务器。这是我的脚本/设置。我也尝试过 cypress circlci-orb 并得到同样的错误，所以我自己尝试运行东西来帮助调试。这是脚本的详细信息：

  - run:
      name: 'Run app tests'
      command: |
        cd app
        yarn install --frozen-lockfile
        yarn lint
        yarn cypress:ci

package.json 脚本：

"cypress:ci": "CYPRESS_BASE_URL=http://localhost:3000 yarn start & wait-on http-get://localhost:3000 && cypress run"

错误：

$ craco start
ℹ ｢wds｣: Project is running at http://192.168.208.3/
ℹ ｢wds｣: webpack output is served from 
ℹ ｢wds｣: Content not from webpack is served from /root/project/app/public
ℹ ｢wds｣: 404s will fallback to /
Starting the development server...

.....
react startup output

Cypress测试启动，出现如下错误

We attempted to make an http request to this URL but the request failed without a response.

We received this error at the network level:

  > Error: connect ECONNREFUSED 127.0.0.1:3000

解决方法： 上传你的资源class！在你的circleci/config.yml

jobs:
  continuous-integration:
    resource_class: large

不明显，因为没有 memory/resource 警告，但根据 circle ci 团队：

When the machine runs out of memory processes are killed which could include the server.

该服务器是我试图启动的 cra-server。我提升了资源 class 并且瞧瞧它运行并且被 cypress 发现了！在我们的案例中，我们将它从中型提升到大型 class，但对您来说可能有所不同。

这是您可以使用的可用资源 class：
