Karma tests process is not autoterminating despite of a 'single' argument

Question

I am creating a build definition on VSTS and I need the task to end in order to start next one.

When I execute

npm run test:single

the tests execute but then the process is not killed automatically and if I press ctrl + c I get an inquiry Terminate batch job (y/n) and even if I hit y then upon next ctrl + c I see

C:\GIT\data>[0] 12 06 2017 11:17:26.232:DEBUG [launcher]: Disconnecting all browsers

In pacakges.json test single is defined as:

"test:single": "npm run tsc && concurrently \"npm run karma-jasmine:autoclose\""

The version of Karma is: "@types/jasmine": "2.5.47"

Question: How to make tests' process terminate when the karma finishes execution of my tests.

Answer 1

I needed to remove spec reporter as it didn't terminate itself after printing the output.
