I'm researching the options I have to make my testing framework (GitHub - commure/datatest: Datatest -- data-driven test framework for Rust) to work on stable, and one of the challenges I have is to make it work nicely with existing #[test]
/#[bench]
tests.
Currently it uses unstable #![test_runner(datatest::runner)]
attribute (https://github.com/rust-lang/rust/issues/50297), but that only works on nightly. It captures existing #[test]
/#[bench]
tests just fine (with some caveats, but it does) -- these work as expected, you can mix and match datatest::
tests and standard ones.
On stable, however, it's a different story. It seems I can use harness = false
in Cargo.toml
to provide my own testing harness, but everything annotated with #[test]
or #[bench]
just disappears from the code if harness = false
.
Any ideas how can I support these?
