I am trying to debug one specific unit test in VSCode with breakpoints.
On the command line, this works perfectly to execute:
go test -v ./cmd/bacalhau -run TestCommands
However, when I select the below to run, I get the following:
{
"name": "Debug Specific Test",
"type": "go",
"request": "launch",
"mode": "debug",
"program": "${workspaceFolder}/cmd/bacalhau/devstack_test.go",
"args": [
"-test.run",
"TestCommands"
],
"env": {
"LOG_LEVEL": "debug"
},
"showLog": true
}
Output:
Starting: /home/user/go/bin/dlv dap --check-go-version=false --log=true --log-output=debugger --listen=127.0.0.1:43095 --log-dest=3 from /home/user/code/bacalhau

I have also tried setting "program": "${workspaceFolder}/cmd/bacalhau/devstack_test.go",
which results in
Starting: /home/user/go/bin/dlv dap --check-go-version=false --log=true --log-output=debugger --listen=127.0.0.1:33479 --log-dest=3 from /home/user/code/bacalhau/cmd/bacalhau

Build Error: go build -o /home/user/code/bacalhau/cmd/bacalhau/__debug_bin -gcflags all=-N -l ./devstack_test.go
no packages to build (exit status 1)`
I have looked at the following resources:
- Debugging Go tests in Visual Studio Code
- https://github.com/golang/vscode-go/blob/master/docs/debugging.md
#1 in the above list looks almost perfect, but I could not get it to work (I don't want to debug ${file}
I want the same unit test to run no matter what file I have open).
How do I set this up correctly?
CodePudding user response:
Modify the "mode"
property in your launch.json
:
"mode": "test", // This should be "auto" or "test"
"program": "${workspaceFolder}/cmd/bacalhau/devstack_test.go",
"args": [],
Or, if you only want to execute the test automatically, you can config it as a task, it's simpler:
{
"version": "2.0.0",
"tasks": [
{
"label": "tmp test",
"type": "shell",
"command": "go test -v ./cmd/bacalhau -run TestCommands",
"problemMatcher": [
"$go"
]
}
]
}
