rust/tests/coverage/async.coverage, branch 1.84.1

coverage: Extract `executor::block_on` from several async coverage tests

2024-09-10T06:08:36+00:00

By moving `block_on` to an auxiliary crate, we avoid having to keep a separate copy of it in every async test. (This also incorporates some small tweaks to the headers in `await_ready.rs`.)

coverage: Treat await similar to a macro

2024-09-06T05:01:59+00:00

Currently `await` is only counted towards coverage if the containing function is suspended and resumed at least once. This is because it expands to code which contains a branch on the discriminant of `Poll`. By treating it like a branching macro (e.g. `assert!`), these implementation details will be hidden from the coverage results.

coverage: Extract hole spans from HIR instead of MIR

2024-07-08T11:22:56+00:00

This makes it possible to treat more kinds of nested item/code as holes, instead of being restricted to closures.

[AUTO_GENERATED] Migrate compiletest to use `ui_test`-style `//@` directives

2024-02-22T16:04:04+00:00

Rollup merge of #120015 - Zalathar:format, r=dtolnay

2024-01-21T05:38:37+00:00

coverage: Format all coverage tests with `rustfmt` As suggested by . Test files in `tests/` are normally ignored by `x fmt`, but sometimes those files end up being run through `rustfmt` anyway, either by `rust-analyzer` or by hand. When that happens, it's annoying to have to manually revert formatting changes that are unrelated to the actual changes being made. So it's helpful for the tests in the repository to already have standard formatting beforehand. However, there are several coverage tests that deliberately use non-standard formatting, so that line counts reveal more information about where code regions begin and end. In those cases, we can use `#[rustfmt::skip]` to prevent that code from being disturbed. ``@rustbot`` label +A-code-coverage

Remove unnecessary `let`s and borrowing from `Waker::noop()` usage.

2024-01-17T20:00:27+00:00

`Waker::noop()` now returns a `&'static Waker` reference, so it can be passed directly to `Context` creation with no temporary lifetime issue.

coverage: Add `#[rustfmt::skip]` to tests with non-standard formatting

2024-01-16T04:56:37+00:00

These tests deliberately use non-standard formatting, so that the line execution counts reported by `llvm-cov` reveal additional information about where code regions begin and end.

coverage: Use `Waker::noop` in async tests

2023-12-15T06:17:20+00:00

coverage: Migrate `tests/run-coverage` into `tests/coverage`
