when you have a conditional in your Gitlab pipeline stage that checks if one thing has succeeded or failed, then you should use this to move or fail your pipeline stage.
Possibility 1 – Fail on String Discovered
if cat log.txt | grep "Failure Abstract" ; then exit 1 ; else exit 0 ; fi
This can fail the pipeline if it discover a string matching Failure Abstract in a file known as log.txt within the present stage.
Possibility 2 – Fail on Code Discovered
Alternatively when you have a file known as response.json that accommodates 200 or 401 codes, then you may fail the pipeline if a 401 is discovered:
if cat response.json | grep 401 ; then exit 1; else exit 0 ; fi
