In light of the stabilization push at #84605 (comment), I have written some tests to more thoroughly capture the current behaviour of the #[coverage(..)] attribute.

These tests aim to capture the current behaviour, which is not necessarily the desired behaviour. For example, some of the error message are not great, some things that perhaps ought to cause an error do not, and recursive coverage attributes have not been implemented yet.

Could you mark the places in tests that show undesirable or at least questionable behavior with FIXME comments?

More thorough status-quo tests for `#[coverage(..)]`

In light of the stabilization push at rust-lang#84605 (comment), I have written some tests to more thoroughly capture the current behaviour of the `#[coverage(..)]` attribute.

These tests aim to capture the *current* behaviour, which is not necessarily the desired behaviour. For example, some of the error message are not great, some things that perhaps ought to cause an error do not, and recursive coverage attributes have not been implemented yet.

More status-quo tests for the `#[coverage(..)]` attribute

Follow-up to rust-lang#126621, after I found even more weird corner-cases in the handling of the coverage attribute.

These tests reveal some inconsistencies that are tracked by rust-lang#126658.
