Let me know if we would like to go ahead with this feature. I am getting my hands dirty enough with compiletest that I feel like I know how to. 😄
@dingxiangfei2009 Thanks for the interest. I would be happy to aid and review this feature, but I feel like we want to make compiletest a bit more maintainable first, see e.g. https://github.com/rust-lang/rust/pull/128070. I think we should not hack on more syntax for directives and error annotations before we figure out how to make the directive and annotation parser itself a bit more robust, lol.

Something that might be nice-to-have is negative ui test error annotations, i.e. that we explicitly want to make sure some diagnostic is not emitted (analogous to FileCheck
check-NOT
annotations).Obviously, you can rely on checking the blessed stderr, but a negative ui test annotation could help communicate intent in the test itself and is less prone to accidentally letting the blessed stderr though.
Note: we should probably try to make the directive parser more robust and less hacky before attempting to add more syntax.
