Description

I've been trying to use rustaceanvim alongside neotest. It's not working, I'm not sure what I'm doing wrong. I have it installed properly, everything else besides the tests integrated with neotest is working.
This is my neotest.lua, I'm using Lazynvim:

Hey 👋

I'm afraid I can't help without a minimal reproducible config and a minimal example cargo project.

Please see the troubleshooting guide in the readme.

[pedrohba1]

https://github.com/pedrohba1/reprod_neotest_rustaceanvim_problem
I've created this reproducible config. It is the exact same config I'm using, inside nvim folder, and I've added a codewars folder where you can try to run Neotest run or Space + T + T to see the tests not running.

[mrcjkb]

Sorry, but I don't have the capacity to bisect other peoples' configs for them.

That's why I provide a minimal config that can be used as a basis for troubleshooting and bug reports.

If you cannot reproduce with the minimal config, then I recommend you start from it, and gradually build up your own config step by step until you find the config or plugin that is causing the issue.
Or, you can bisect your existing config (by disabling plugins, etc.).

[pedrohba1]

Hey, nevermind, sorry to bother you. I did something really stupid while configuring the rust project and it was not working with rust-analyzer at all and I didn't realize. Thanks for the suggestions!
Closing this in shame of my stupidity...
