Bug

• version

npm -v start-server-and-test
5.6.0

• platform
  linux: alpine-node
• expected behavior
  Exits with code 0 at end of test
• actual behavior
  After tests complete, I get Error: spawn ps ENOENT, and exits with code 1

    All specs passed!                           00:27       15       15        -        -        -  

events.js:167
      throw er; // Unhandled 'error' event

It looks like this started when I added env to the beginning of start:web?

    "start:web": "env APP_ENV=dev webpack-dev-server --inline --hot --host 0.0.0.0",
    "test:e2e": "start-server-and-test start:web http-get://0.0.0.0:8080 cy:run",
    "cy:run": "cypress run",

I need to keep env. Any suggestions on what I should try? Thanks!

This catch() function is not being called:

startAndTest({ start, url, test }).catch((e) => {
  console.error('here', e);
  process.exit(1);
});

Had the same problem, I switched the docker base to node:10.11.0-alpine and the start-server-and-test package version from 1.7.11 to 1.7.1 and somehow these changes did the trick for me.

I had the same problem in a different project. The reason is that alpine doesn't have the 'ps' command istalled by default.

I fixed it by installing it in my container:
sudo apt-get update && sudo apt-get -y install procps

Thank you! That fixed

If you were using alpine, wouldn't this apt-get command have to be apk add?
