Gradle exec task hangs when running javascript unit tests with Karma

Question

I am trying to run my javascript unit tests from my build tool gradle. If I from my project source repository run karma the tests pass, but from that same location if I run the same commands using gradle the test hangs. I have to cntl + C out.

The browser that karma launches just hangs open. Upon further inspection I can see that my tests are passing, yet the browser doesn't exit.

karma start --single-run true

Gradle Task

task karma(type:Exec) {
    commandLine 'karma', 'start', '--single-run true'
}

Karma Console

I pulled this gradle task directly from stackoverflow here

Answer 1

I figured it out.

In my karma.conf.js file I had

singleRun: false

once I changed it to true it worked

FIX

change this setting in your karma.conf.js file

singleRun: true
