Times out in Github Action

Bug Report

I am running version 1.11.6. My server is nodejs, rendering server side EJS templates. I am using Nightwatch for tests. My scripts are: ci: start-server-and-test start http-get://localhost:8080 test:e2e start: node server.js "test:e2e": "nightwatch --env default --headless"

Running npm run ci works perfectly locally, but when I run in a Github Action pipeline it is timing out. As you can see, I am logging a confirmation that our express server is up and running. I am getting the following error.

> start-server-and-test start http-get://localhost:8080 test:e2e

1: starting server using command "npm run start"
and when url "[ 'http-get://localhost:8080' ]" is responding with HTTP status code 200
running tests using command "npm run test:e2e"


> project@1.0.0 start /home/runner/work/project/project
> node server.js

Express server listening on port 8080

Im just getting this on repeat with debug output on… making HTTP(S) head request to url:http://localhost:8081/ ... HTTP(S) error for http://localhost:8081/ Error: connect ECONNREFUSED 127.0.0.1:8081

However localhost:8081 should be responding, just not doing it for the script for some reason

If you have any kind of response (500 in this case), most likely the issue is coming from the server itself that behaves differently on CI.

There is also an upstream issue, btw: https://github.com/jeffbski/wait-on/issues/86.

You can also try replacing start-server-and-test start <url> test with concurrently + wait-on:

concurrently --kill-others \
  'start' \
  'wait-on --verbose <url> && test'
