Show only reason why test failed without traceback

Hello,

My current test is run from a python script looking like this:

from tavern.core import run

success = run("C:\FrameWork_FAIL\\tests\YAMLFiles\\test_fileService.tavern.yaml", pytest_args = ["--tb=short"])

Running like this is really verbose even with pytest_args = [“–tb=line”] . The output looks like

Is there any way for me to show only the reason why the test failed? Something like:

--------------------------------------------------------- Captured log call ----------------------------------------------------------
base.py                     41 ERROR    Status code was 301, expected 400

Thank you for the response! 😃

@chrisinmtown Is there a workaround to get non-verbose-overkill output?

Edit: to answer my own question after trying it myself, it appears the new traceback is default in 1.0:

https://tavern.readthedocs.io/en/latest/debugging.html#new-traceback-option … “This output style will become the default in version 1.0.”

For people who land here in 2020, version --tavern-beta-new-traceback seems to be supported by Tavern version 0.34.0 but not by version 1.0.0 that was released 5 Apr 2020.
