"Run test" code lens runs all tests with a matching name

[oli-cosmian]

The lens on foo_bar will only run the foo_bar test, but the lens on foo will run both tests.

mod a {
    #[test] fn foo() {}
}
mod b {
    #[test] fn foo_bar() {}
}

The lens should pass the module path to the cargo test invocation in order to not run all tests with a matching name

I am having the same issue.

The problem is that the current implementation of CodeLens in rls simply uses RegEx to locate the fn name and passes it to cargo test without parsing source code or mod structures.

https://github.com/rust-lang/rls/blob/adf13c2527d3a11850fb0f79323768596f78f4f2/rls/src/actions/run.rs#L51

I think it is nearly impossible to fix without a non-trivial refactor.

I had same problem and investigated rls and cargo-test.

It seems --exact flag with fully qualified name of the test function, like a::b::tests::test_name, will do the job. But as @Gowee said above, it requires some understanding of rls.
