[SOLVED] Run Single Go Test With launch.json Configuration

Run Single Go Test With launch.json Configuration

Is it possible to run a single Go test in VS Code with a launch.json configuration?

Here's my OS and Go version

Windows 11
Delve Debugger Version: 1.24.0
go version go1.23.4 windows/amd64

Right now, the closest thing I have is running all tests in a file with this configuration:

// Attempt at running a single Go test
{
    "name": "Go run single test",
    "type": "go",
    "request": "launch",
    "mode": "auto",
    "program": "${file}",
    "args": [
        "^TestDoThing"
    ],
}

I saw someone add the test name to the args in this question, but it didn't affect my results. All the tests in the file still run. Running a single test with a launch.json configuration is more of a convivence than a requirement for me. But I couldn't find any other questions about it or documentation/articles, so I thought it was worth asking about.

Solution

So in principle i would say you can just put a breakpoint directly in test case and run it from GUI by clicking debug test above test case name. However you can try the following:

{
    "name": "run-concrete-test",
    "type": "go",
    "request": "launch",
    "mode": "test",
    "program": "${workspaceFolder}/path/to/your/test-file-dir",
    "args": [
        "-test.run",
        "^TestDoThing"
    ],
    "showLog": true
}
