Nextest doesn't work in workspace where Cargo.toml of workspace is not hierarchically higher than crates

What I think the issue is

I believe that nextest assumes that the workspace Cargo.toml will always be in a parent folder of the crates the workspace contains.

Thank you! I've never seen this before to be honest. Do you have a reference in the Cargo documentation for it?

[Elrendio]

Hi @sunshowers , I'm sorry but I didn't understand what reference do you want me to provide?

[sunshowers]

Thanks. I had another look at your repro, and to be honest I didn't know that you could use .. in workspace members! It definitely seems rare, I've never seen a Rust project in the wild do this.

This would have to be addressed in the underlying guppy library (also maintained by myself), https://github.com/guppy-rs/guppy. I don't plan to fix this myself but a patch would be welcome.

I don't plan to work on this, but a patch would be welcome.

I checked the error message, if do not restrict manifest path must within workspace path, nextest can run tests at MinimalRepo. If you are sure this restriction can be bypass optionally, I can try provide patch to Guppy and Nextest.

Patch is ready now, for guppy repository, please review
