我正在嘗試使用斷點在 VSCode 中除錯一個特定的單元測驗。
在命令列上，這可以完美地執行：
go test -v ./cmd/bacalhau -run TestCommands
但是，當我選擇以下運行時，我得到以下資訊：
{
"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
}
輸出：
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

我也嘗試過設定"program": "${workspaceFolder}/cmd/bacalhau/devstack_test.go",導致
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)`
我查看了以下資源：
- 在 Visual Studio Code 中除錯 Go 測驗
- https://github.com/golang/vscode-go/blob/master/docs/debugging.md
上面串列中的#1 看起來幾乎完美，但我無法讓它作業（我不想除錯${file}，無論我打開什么檔案，我都希望運行相同的單元測驗）。
如何正確設定？
uj5u.com熱心網友回復：
修改"mode"您的屬性launch.json：
"mode": "test", // This should be "auto" or "test"
"program": "${workspaceFolder}/cmd/bacalhau/devstack_test.go",
"args": [],
或者，如果您只想自動執行測驗，您可以將其配置為任務，它更簡單：
{
"version": "2.0.0",
"tasks": [
{
"label": "tmp test",
"type": "shell",
"command": "go test -v ./cmd/bacalhau -run TestCommands",
"problemMatcher": [
"$go"
]
}
]
}
