My package.json below for karma

My Error->

Similar Error like Error thrown in afterAll [object Object]

Banging my head on this issue from the past 2 weeks, still no success.

Have recently updated Angular 8 to Angular 11.2.4.

I have total of 1000+ test cases which are failing randomly , but when runs individually it works.

Need help on this issue

Facing the same issues. Random different test cases failing each time. Test cases are failing without any proper error unable to debug. Frustrating!!!

yaa, test cases are also falling the same for me I don't know why this issue coming and why test cases are failing and only 1 test case fail and it changes every time when I run ng test or ng test --no-watch --code-coverage always. it's ridiculous and frustrating.

Test cases are falling good but they are not giving a proper error message and without a proper error message how can we remove such an error.
