Substitution for values from other sections with positional arguments

[1Mark]

Lets say my config is

[testenv]
{[testenv]test1}
{[testenv]test2}
    
[testenv:test1]
commands = pytest {posargs: -m blah1}

[testenv:test2]
commands = pytest -x {posargs: -m blah2}

I want to only allow posargs to be passed when running tox -e test1 or tox -e test2 but any posargs passed to tox directly shouldn't be forwarded.
That is, these work

tox -e test1 -- -m cats
tox -e test2 -- -m dogs

tox -- -m cats shouldn't error, or be ignored since I don't want pytest to be involved twice with the same args.

Please note my main point is that I want the commands in [testenv:testN] to be reused inside [testenv] without allowing substitution AND not duplicating command in [testenv:testN].
I.e. I don't think doing this is a good solution since if I alter [testenv:test1] I have to manually alter [testenv]

[testenv]
pytest {posargs: -m blah1}
pytest -x {posargs: -m blah2}

[testenv:test1]
commands = pytest {posargs: -m blah1}

[testenv:test2]
commands = pytest -x {posargs: -m blah2}

TL;DR I want to be able to Substitute for values from other sections with positional arguments and not allow the top level command to forward the arguments.

Maybe if I could store [testenv:test1]'s command in a variable then reuse that in [testenv] but it's unclear how to do this in the docs.

We don't support this behaviour currently and I don't think we plan to support it. This would make the configuration be even more complicated than it is today and I'm personally not comfortable with it.

Do any workarounds exist?

I don't think so. You'll just need to duplicate some settings 👍
