Trying to debug minitest

[tdegrunt]

Trying to debug a minitest, using the following configuration.

        {
            "type": "ruby-debug",
            "request": "launch",
            "name": "Debug current test",
            "program": "${workspaceFolder}/bin/rails",
            "programArgs": [
                "test",
                "${relativeFile}:${lineNumber}"
            ],
            "useBundler": false
        }

But basically nothing happens, I see rails starting in the debug console, but the process ends straight away without debugging. Am I doing something wrong? I see threads starting in the call stack. I have "break on raised exceptions" off, because otherwise I'd see all exceptions (caught or not).

Clicking on "Debug" here doesn't work, as that is tied to the ruby plugin.

I've tried useBundler: true, but that gives the same results.

Debugging using 'rails server', using the following configuration works:

        {
            "type": "ruby-debug",
            "request": "launch",
            "name": "Rails server",
            "program": "${workspaceFolder}/bin/rails",
            "programArgs": [
                "server"
            ],
            "useBundler": false
        }

It quickly ends in: "fatal (exception reentered):" though - in:
/Users/tdegrunt/.rbenv/versions/2.7.2/lib/ruby/gems/2.7.0/gems/actionpack-6.1.4/lib/action_dispatch/middleware/static.rb:140

Does minitest work if you specify an explicit file and line, e.g., instead of "${relativeFile}:${lineNumber}" use "/path/to/test.rb:123"?

That doesn't work, no. I've also tried without the line-number in the path, just to be sure, but same results.
There's output in the debug console, which I always see (sadly - deprecation warnings).

This might be related to how the debugger's process monitor manages threads. I haven't identified a root cause yet, but I'm looking into it.

If there's anything I can do, please let me know

I have the same problem. I see two threads appear in the call stack, then disappear immediately. I don't see any output in the debug console though.

Any progress on this?
