[Feature request] Setup and teardown for tests

[Adrien-Bodineau]

What about introducing new tests attributes for edition 2024 to allow global setup/teardown in tests ?

Something like

#[setup]
fn foo() {
    // do stuff...
}

#[teardown]
fn bar() {
    // undo stuff...
}

setup would run before all tests in its module and teardown after

You might want to open an issue on https://github.com/rust-lang/libtest-next instead.

Well, sounds like something that would definitely be useful to have without adding a dependency. I'd gladly use such a feature.

libtest-next contains experiments for a rework of the existing testing support in rustc itself. I guess you could see the libtest-next issue tracker as a list of feature requests for whatever the new implementation of testing support for rust will end up.

AFAIK libtest itself is more or less feature-frozen at the moment, and it is extremely unlikely to accept new feature requests. I see you have already filed assert-rs/libtest2#79.

I'm going to leave this open for T-testing-devex to decide, but I think it might be closed in favor of libtest-next's issue tracker instead.

Actually, this feature request is a duplicate of #117668. I'm going to close this in favor of the earlier request. Thank you for the request.

Oh I see. Didn't know test was in rework. It's great news!
