cannot debug single test in VS Code

[zxy198717]

click debug test, but debug console output:

Starting: [/Users/tom/go/bin/dlv]() dap --check-go-version=false --listen=127.0.0.1:60712 --log-dest=3 from [/Users/tom/workspace/playground/tests]()
DAP server listening at: 127.0.0.1:60712
Type 'dlv help' for list of commands.
testing: warning: no tests to run
PASS
Process 38235 has exited with status 0
Detaching
dlv dap (38199) exited with code: 0

seems no test detect, works ok when click run test.

This works fine for me. Post your environment details and a full compilable example.

@brackendawson seems cannnot debug test case in file other_test.go

[brackendawson]

With the above file layout I can re-create this on Go 1.18.

This run configuration works though:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Launch TestFar",
            "type": "go",
            "request": "launch",
            "mode": "test",
            "program": "${fileDirname}",
            "args": ["-test.run", "PlaygroundSuite/TestFar"],
        }
    ]
}

I suspect this is probably a bug in the run configuration generated by the "debug test" button in the VSCode Go plugin, I'm actually surprised it works with testify/suite at all. I don't know how to see the run configuration VSCode uses here, probably best to open an issue here.

Which I see you already did golang/vscode-go#2189

[zxy198717]

Thanks, will track it by golang/vscode-go#2189.
