Is there a way to use tags as an "opt in" behavior? For example, running

./pants test ::

wouldn't include certain tests unless you specifically called out their tags. I think in python, it's likely recommended to use pytest markers, but that can cause issues since

./pants test ::

with a pytest marker added would include a lot of modules that don't end up running any tests and then report a false failure.

You can add

tag = ["-tag_to_exclude"]

under

[GLOBAL]

in

pants.toml

. This’ll work as long as no one overrides it with

--tag

,

PANTS_TAG

etc.

https://github.com/pantsbuild/pants/issues/15012 is related, although doesn't provide much insight beyond pytest markers

Hmm that makes it seem like the above suggestion wouldn't work then?

I tested it a while ago.

pants --tag='+manual' lint path/to/manual/tests/::

as written in the issue does not work, but

pants --tag="['+manual']" lint path/to/manual/tests/::

does. But

tag = ["-manual"]

will also exclude it from everything, like

fmt

,

lint

etc., so it’s suboptimal if one only wants to exclude it from

test

.

Gotcha. We only use

test

right now so I think we'd get by.
