clippy::wildcard_imports triggers for use super::super::*; under a module in a tests.rs

[LikeLakers2]

Summary

If you use modules to sort your tests under a tests.rs file, Clippy can trigger a false positive if you use use super::super::*;. This even includes if you're using it to import items from within the tests.rs file.

Lint Name

clippy::wildcard_imports

Reproducer

I tried this code:

/src/lib.rs

#![warn(clippy::wildcard_imports)]

#[cfg(test)]
mod tests;

#[must_use]
pub fn add(left: usize, right: usize) -> usize {
	left + right
}

/src/tests.rs

mod add {
	use super::super::*;
	
	#[test]
	fn it_works() {
		let result = add(2, 2);
		assert_eq!(result, 4);
	}
}

I saw this happen (make sure you execute cargo clippy --tests to compile the tests):

I expected to see this happen:
