Repro steps

  • Upgrade Angular CLI to V6 (global/local)
  • Upgrade Angular to V6
  • Upgrade other dependencies
  • Ensure karma.conf.js has singleRun: false in it
  • Run ng t OR run ng t --single-run=false

Observed behavior

If ng t is run, tests will run successfully but browser window will close on finish (despite karma.conf.js having singleRun: false inside it)

If ng t --single-run=false is run, it errors: Unknown option: '--singleRun' Note that running ng t --no-single-run creates the same error.

Desired behavior

I would like the browser window to remain open, as it always did, pre-upgrade

I switch ng test --single-run to ng test --watch=false and it is works good.

Other Answers:

This works:

ng test --watch


--no-watch should also work (more elegant).

The wiki of the angular-cli says:
You can run tests a single time via --watch=false
tried it out and it works

is ng test --single-run is equivalent to ng test now in angular6?
I observed same behavior.
