pytest - addopts - environment variables

[nmt1]

description

I don't understand how I can change the addopts in pytest.
I am not sure what is the approach, and can't find a clear/strict way within the pytest documentation.

content of pytest.ini

[pytest]
addopts = --strict

content of conftest.py

exitfirst = os.getenv("env_exitfirst", "false") # typically controlled via Jenkins

if exitfirst == "true":
write --exitfirst to addopts?

Hi @nmt1 why not just specify the -x | --exit-first flag in the pytest.ini directly via addopts = --strict -x. I would also like to point you to the --max-fail flag as thats possibly something of interest to you also (if you are in and around exitfirst behaviour).

Now if you must use the env vars via jenkins as mentioned in your original comment, this is available:

export PYTEST_ADDOPTS="-x"

Please let me know if this is useful for you, if you have any other questions I can try my best to assist you.

Thanks for the answer!

where can I write the cmd: export PYTEST_ADDOPTS="-x"
is it in a pytest_configure hook?

No it’s just an environment variable 😎
