在 travis 上的 create-react-app 上运行 nightwatch 测试

Question

我在 travis 上的 create-react-app 服务器 (npm start) 上运行 nightwatch 测试时遇到问题。我正在启动 creat-react-app

.travis.yml:

before_script:
  - npm --prefix ./client start ./client &
script: npm run test-ci

然而，当守夜人运行时，我总是得到

Starting the development server...
Starting selenium server... Warning: The 'no-use-before-declare' rule requires type information.
ts-loader: Using typescript@2.5.3 and /home/travis/build/client/tsconfig.json
started - PID:  4017

You can now view app in the browser.
  Local:            http://localhost:3000/
  On Your Network:  http://172.17.0.3:3000/
Note that the development build is not optimized.
To create a production build, use npm run build.
Error retrieving a new session from the selenium server
Connection refused! Is selenium server started?
{ Error: socket hang up

但是，在本地启动和运行 nightwatch 测试非常完美。

问题出在 Chrome 上，而不是 react 或 Nightwatch 的问题。
