How to use rustTestExplorer.rootCargoManifestFilePath?

[ibraimgm]

Hello! I have a repository with the following structure:

some_project   <--- project root (this is the folder I open)
├── c_project
│   └── main.c
├── rust_project
│   ├── Cargo.toml
│   └── src

Since Cargo.toml is not on the root path, test explorer does not show any testes on the UI. If I open the rust_project folder directly, it works as expected.

Looking at the plugin contributions, I noticed rustTestExplorer.rootCargoManifestFilePath. I tried the following combinations:

• ./rust_project
• ./rust_project/Cargo.toml
• ${workspace}/rust_project
• ${workspace}/rust_project/Cargo.toml
• /home/myuser/myprojects/some_project/rust_project
• /home/myuser/myprojects/some_project/rust_project/Cargo.toml

But none of them worked (tests still weren't showing on the UI).Am I doing something wrong here? Or this option is bugged/not implemented? Not sure if it helps, but the test lens from rust-analyzer do show up and work as expected.

hi 👋

are you using a multi root work space by any chance? or just opening one directory level higher?

[ibraimgm]

No multi root shenanigans; just opening one level higher.

Anything interesting showing in the logs?

I tried something similar. The logs report that no Cargo.toml file is found in the workspace root directory.

Thank you both, will try to dig into it later this week

I had some free time to look into this. I believe I found a solution. Let me know what you think and if there should be any changes that I should make! #186

[calebcartwright]

Awesome, thanks so much @EricHenry!

If somebody could fix the rootCargoManifestFilePath, I can wait for the official Test Explorer API support forever.
