Unable to run individual parameterized tests - e.g. with test_case

[sazzer]

Using crates for parameterized testing doesn't allow me to run the individual tests using the "Run Test" action. I can run the entire set of tests in the module, but not a single method.

The reason for this is because the tests are run with --exact but the name provided is not the exact test name, since the exact test name is ultimately generated.

For example, given the test:

    #[test_case("", ParseUserIDError::Malformed ; "Blank")]
    fn failed_parse(input: &str, expected: ParseUserIDError) {
        let parsed: Result<UserID, ParseUserIDError> = input.parse();
        let_assert!(Err(err) = parsed);
        check!(err == expected);
    }

Running this will execute:

cargo test --package universe --lib -- users::model::user_id::tests::failed_parse --exact --nocapture <

Whilst the exact test name is users::model::user_id::tests::failed_parse::blank (And an additional test function for each occurrence of test_case)

If I use the "Run Test" action on the module as a whole, it executes without the --exact flag and thus works.

Without --exact if there would be a test called foo and foobar, trying to run foo would run both. It would be better to keep passing --exact, but implement expansion of attribute proc macros.
