This PR has started as an effort to proceed from the feedback in rust-lang/rust-clippy#12861. - Checks test functions (functions marked with `#[test]` annotation) for redundant "test_" prefix. - Auto-fix is supported (and handles collisions gracefully, see below). - If removing "test_" prefix from, say, `test_foo()` results in a name collision (either because function `foo()` is already defined within the current scope, or because the `foo()` call exists within function -- thus creating an unwanted recursion), lint suggests function rename, warning the user that a simple trimming of `test_` prefix will result in a name collision. - If removing "test_" prefix results in invalid identifier (consider `test_const`, `test_`, `test_42`), then again no auto-fix is suggested, user is asked to rename function, with a note that a simple prefix trimming will result in an invalid function name. (`Applicability::HasPlaceholders` is used and user is suggested to: drop `test_` prefix + add `_works` suffix, i.e. `test_foo` becomes `foo_works` -- but again, user has to apply those changes manually). - If trimmed version of the function name is a valid identifier, doesn't result in name collision or unwanted recursion, then user is able to run auto-fix. fixes rust-lang/rust-clippy#8931 changelog: new lint: [`redundant_test_prefix`] |
