Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @sfackler (or someone else) soon. If any changes to this PR are deemed necessary, please add them as extra commits. This ensures that the reviewer can see what has changed since they last reviewed the code. Due to the way GitHub handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed. Large or tricky changes may require several passes of review and changes. Please see the contribution instructions for more information. |

Filter matching is by substring by default. This makes it impossible to run a single test if its name is a substring of some other test. For example, its not possible to run just "mymod::test" with these tests: mymod::test mymod::test1 mymod::test_module::moretests You could declare by convention that no test has a name that's a substring of another test, but that's not really practical. This PR adds the "--exact" flag, to make filter matching exactly match the complete name.

Seems reasonable to me, though I'll defer to the @rust-lang/rools team. This is something that's bugged me in the past! |
