Angular testing with karma running tests infinitely

Hey I have a problem with testing in angular.

If I changed the regex on test.ts to look for *.component.spec.ts files there is no problem 72 test succeeded and same for *.service.spec.ts 128 test succeeded. But if i changed regex to look for all .spec.ts files the test runner not stopping. It continue counting after all tests are done. I tried with --watch=false or autoWatch: false these are not working for me.
