# Objective - There are several redundant imports in the tests and examples that are not caught by CI because additional flags need to be passed. ## Solution - Run `cargo check --workspace --tests` and `cargo check --workspace --examples`, then fix all warnings. - Add `test-check` to CI, which will be run in the check-compiles job. This should catch future warnings for tests. Examples are already checked, but I'm not yet sure why they weren't caught. ## Discussion - Should the `--tests` and `--examples` flags be added to CI, so this is caught in the future? - If so, #12818 will need to be merged first. It was also a warning raised by checking the examples, but I chose to split off into a separate PR. --------- Co-authored-by: François Mockers <francois.mockers@vleue.com>
