Bug: Assert causing INTERNALERROR in pytest 6.0.0

[parijatm]

Issue:
Upgrading to pytest version 6.0.0 breaks nightly regressions by causing INTERNALERROR upon encountering failed DRC checks. This error causes the overall regression to silently pass without running all circuits.

Temporary fix:
I have forced our Docker build environment to explicitly use pytest version 5.4.3 (#473). We should upgrade to pytest 6.0.0 and fully root-cause the INTERNALERROR issue at some point.

I have root-caused the INTERNALERROR to a pytest bug that is exercised when you generate junit.xml and use --tb=line.

Can we drop the --tb=line? Tagging both @kkunal1408 @stevenmburns since I am not sure who added it.

The other option would be to leave it as it is now (use version 5.4.3) and await a pytest fix.

I added the tb=line so that only the DRCs count gets populated when the assert statement for DRC count=0 fails. Without this command, it dumps a long log (terminating after a fixed length) instead of a concise view thus affecting the readability of the report.

Got it. Let's stick with pytest 5.4.3 until we get a 6.0 fix in that case.

Bug has been addressed in pytest 6.0.2. ALIGN will be contoured with latest pytest once PR #449 is merged with master.
