Having trouble debugging single rails minitest file

[vmcilwain]

Hello,

I am attempting to debug a single minitest file in a rails app but I am having some trouble getting the debugger to launch properly.

My current environment is as follows:

macOS: 14.1 (M2 Chip)
rdbg 1.8.0
vscode: 1.84.2 (Universal)
vscode-rdbg: 0.1.0
zsh 5.9 (x86_64-apple-darwin23.0)

My current debug launch config is:

{
  "type": "rdbg",
  "name": "Debug current file with rdbg",
  "request": "launch",
  "command": "rails",
  "script": "test ${relativeFile}:${lineNumber}",
  "args": [],
  "askParameters": true,
  "env": {
    "RUBY_DEBUG_OPEN": true
  }
}

The prompt displays the following command for me to execute:

rails test test/models/product_test.rb:22

After confirming, I get the following output in the debug console:

Ruby REPL: You can run any Ruby expression here.
Note that output to the STDOUT/ERR printed on the TERMINAL.
[experimental]
  `,COMMAND` runs `COMMAND` debug command (ex: `,info`).
  `,help` to list all debug commands.

I am not sure how to verify if the environment variable was set or if it is even useful in this case.

I confirmed the test does run correctly when I copy/paste it in the terminal (warp).

Has anyone managed to get this to work by chance?

What is your question?
BTW why do you use it: "RUBY_DEBUG_OPEN": true?

Sorry I am just now getting back to this.

I am going to close this ticket and open another one with more details of what I am doing and what I am experiencing if I run into any issues.
