Angular: ng test runs but doesnt execute test cases

Question

I get the below messages after executing command ng test. It runs with out any errors but doesn't execute test cases. Any idea why it's not executing the tests?

My project is upgraded from Angular 2 to 4, 5 & now 6. Is it because the karma library has not upgraded properly?

I have created new Angular 6 project and tried ng test it works there but doesn't work on my project. I have deleted the node_modules folder and installed it by npm install, but it is still not working. Any other sugessions?

I got this working by removing ngx-translation import. But its not fix as with out importing translation I wont be able to proceed further.

Anyone implemented the ngx-translation in Unit test cases.

Try opening a browser to localhost:9876 after you run ng test and see if that works. The output above indicates it has no captured browser to run the tests in. If that doesn't work, can you provide some working code so others can debug? — Ash

It actually opens browser and prints Security in it and doesnt execute test cases. Do you any idea like why it prints Security? — Krishna

This happens when jasmine goes in to a loop. Actually because of my translate service, It was going in the loop and which was causing karma not to run any test cases and exit, giving error 0 of 43 test executed.

Just for the information: To find the exact issue about this, run the test case with -sm=false.

C:\Angular>ng test -sm=false

I was stuck in this for a while. Above command gave me the exact issue needs to be resolved. Hope it will be helpful to others getting this issue.
