Testing multiple workspaces at once?

[bes]

I understand that this is probably out of scope for nextest itself - so I'll explain some stuff before coming to the question

Current setup

I work in a git with multiple workspaces: backend, frontend, graphics-renderer, native-ffi, wasm-ffi, cli, demo application, and so on. This setup is convenient because everything is tested together. We don't publish any crates which adds to the convenience.

To test everything i have a Zellij multipane with bacon running nextest in each pane for each workspace. This works "well" while developing but obviously not optimal since each nextest runs many cores to optimize, and we kind of break that optimization by running multiple nextest.

Question

Running nextest in a multi-workspace way will probably never be implemented (right?), so my ask here is if there are any ways to improve this? Is anyone else doing something similar? Thanks!

Thanks for the question. In theory nextest could support the GNU Make jobserver protocol for this, though an interesting question is whether we'd want the jobserver to be inherited by tests. (Probably not?)

See https://www.gnu.org/software/make/manual/html_node/Job-Slots.html

Happy to take a draft PR for this.
