Angular CLI 6 Unknown option: '--singleRun'
With older versions of angular-cli, you used to be able to use both --singleRun and --watch=false for the same thing. Now they removed --singleRun.
You can still use ng test --watch=false
Tests will execute after a build is executed via Karma, and it will automatically watch your files for changes. You can run tests a single time via --watch=false or --single-run.

Starting from Angular v6, you don't need to specify --single-run
