unit-testing - 在 Visual Studio Code 中调试 Go 测试

Question

在我的 Windows 机器上，我安装了 Visual Studio Code。要手动运行测试，我进入控制台到项目文件夹并输入

go test main_test.go

它完美地工作。

但我有一种情况需要调试我的测试以了解发生了什么。

为此，我打开 launch.json 并添加一个配置

  {
        "name": "Tests",
        "type": "go",
        "request": "launch",
        "mode": "test",
        "remotePath": "",
        "port": 2346,
        "host": "127.0.0.1",
        "program": "${workspaceRoot}",
        "env": {},
        "args": [
           "main_test.go"
            ],
        "showLog": true
    }

按F5之后

2017/03/29 13:28:11 server.go:73: Using API v1
2017/03/29 13:28:11 debugger.go:68: launching process with args: [./debug.test main_test.go main_go]
not an executable file
Process exiting with code: 1

知道为什么会出现此错误以及它正在寻找什么可执行文件吗？

为了启动调试器进行测试，我为 launch.json 添加了一个配置

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Code",
            "type": "go",
            "request": "launch",
            "mode": "debug",
            "remotePath": "",
            "port": 2345,
            "host": "127.0.0.1",
            "program": "${workspaceRoot}",
            "env": {},
            "args": [],
            "showLog": true
        },
        {
            "name": "Test Current File",
            "type": "go",
            "request": "launch",
            "mode": "test",
            "remotePath": "",
            "port": 2345,
            "host": "127.0.0.1",
            "program": "${file}",
            "env": {},
            "args": [],
            "showLog": true
        }       
    ]
}

此外，此配置不支持标签。必须禁用测试文件中的所有标签

// +build unit
