Parallel Build steps in Team City

Question

I am Pretty new to Team City and have been set with a task of creating a CI build.

The thing I trying to build is an angular2 app with protractor e2e tests.

All the other build steps in Team City run ok but I am having trouble trying to run the step that does the e2e test.

if I was to do this locally I would open a cmd window and type...

npm run start

I would then open another command window and type...

npm run e2e 

How do I run parallel steps in Team City?

Answer 1

Build steps cannot be run parallel in TeamCity. What you need to do, is create a script that runs 'npm run start' in background, and then runs 'npm run e2e'. You can use command line runner to run the script

Answer 2

I still couldn't get the forever thing working properly for me so I created my own node script that fires up live-server and then executes npm run e2e and that seems to have done the trick thanks for your help though Oleg.

This is how I did it in the end...

const exec = require('child_process').exec;
var psTree = require('ps-tree');

const server = exec('live-server ./dist --port=3000 --no-browser');
const tests = exec('npm run e2e');

tests.stdout.on('data', function(data) {
  console.log(data);
});
tests.stderr.on('data', function(data) {
  console.log(data);
});
tests.on('close', function(code) {
  console.log('closing code: ' + code);
  exec('taskkill /PID ' + server.pid + ' /T /F');
});
