vscode|go测试调试配置

单测

在vscode中,带_test的go源文件里的测试函数有有专门的优化,可点击”run test”,”debug test”一键测试

配置

在settings.json可以指定go buld参数如ldfalgs,gcflags等

"go.buildFlags": [
    "--ldflags -r=${workspaceRoot}/lib"    // works for 'debug test' but not 'run test'
    // "-ldflags=-r ${workspaceRoot}/lib"  // works for 'run test' but not 'debug test'
],
"go.buildTags": "linux",
"gopls": {
    "build.buildFlags": [
        "-tags=linux",
    ]
}

在2023.10.27使用go1.21和最新的vscode,gopls遇到一个问题,”run test”,”debug test”对ldflags参数解析行为不一致
可参考如上配置

"go.buildFlags": [
        "--ldflags=-r=${workspaceRoot}/clib"
],

2023.11.3测试上面这个可用,参考issue

项目debug

launch.json

在左侧的debug添加配置如下,buildFlags指定go build参数,debug模式必须传–gcflags=’all=-N -l’

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "name": "GO:Launch Package",
            "type": "go",
            "request": "launch",
            "mode": "auto",
            "program": "${workspaceRoot}",
            "buildFlags": "--gcflags='all=-N -l' --ldflags='-r ./lib'"
        }
    ]
}

也可使用launch.json配合tasks.json,通过tasks定义任务构建项目生成可执行文件

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        // exec: debug a precompiled binary
        // The binary must be built with go build -gcflags=all="-N -l" to disable inlining and optimizations that can interfere with debugging.
        {
            "name": "UC:Debug",
            "type": "go",
            "request": "launch",
            "mode": "exec",
            "asRoot": true,
            "program": "${workspaceRoot}/program",
            "console": "integratedTerminal",
            "preLaunchTask": "go: build (debug)"
        },
    ]
}

tasks.json,label指定任务名称,在launch.json中通过preLaunchTask指定在debug前需要执行的任务

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "go: build (debug)",
            "type": "shell",
            "command": "go",
            "args": [
                "build",
                "-gcflags=all=-N -l",
                "-ldflags=-r ./lib",
                "-tags=linux",
                "-o",
                "${workspaceRoot}/program"
            ],
            "options": {
                "cwd": "${workspaceRoot}"
            },
        }
    ]
}
