Different result in automated testing, jenkins

I wrote over 300 tests and local seems to be anything fine.

But when i ran these tests on a jenkins via a docker build, it throws me :

  ElementDetailElementComponent
    ✖ should be as a popup
      HeadlessChrome 0.0.0 (Linux 0.0.0)

this might happen due a async. service call I guess.

this is my script :

"test": "ng test --browsers Chrome_no_sandbox --source-map=false --watch false",

My questions :

1. What do I have to do to get the same errors in local 2.Is there a way to detect the exact wrong lines that cause these errors?
