Pre-RFC `#[test]` on `mod`

I believe that you are an expert and know more about the mechanism.

I've been in the implementation in order to work on the impl for my own pre-RFC:

Pre-rfc: Skippable tests

Summary Some test cases have indeterminite results in some cases. These cases should be distinct from a passing or failing state of a test today. It is possible to turn tests off at compile time by using features determined by a build.rs script, however, this does not work well for cross compilation or when the build and test environment are otherwise quite different. Motivation Currently, tests in Rust's libtest have only a handful of end results: success failure (panic) should panic (whic…

The filter does not work on the functions inside the #[test] mod, because they are parts of a test case but not a test case itself.

That's fine; I think it just needs to be considered and documented, that's all.

@yanganto

In the future, when we look much deeper at the implementation, there may be something that needs to conquer, please give a hand on this if you can. Thanks in advance.

I can certainly offer my viewpoint, but I have no real weight to get anything merged . Being able to see corner cases and holes in combinations of things is just a knack I have .
