Question

This article描述了如何设置VS Code设置，以将调试目标指向单元测试项目的生成输出。因此，我将这样设置：

{
    "explorer.confirmDragAndDrop": false,
    "git.allowForcePush": true,
    "git.autofetch": true,
    "window.zoomLevel": 0,
    "csharp.unitTestDebuggingOptions": {
        "sourceFileMap": {
            "C:\\git\\MsTester\\bin\\Debug\\netcoreapp2.1": "C:\\git\\MsTester\\bin\\Debug\\netcoreapp2.1"
        }
    },
    "files.autoSave": "afterDelay",
    "files.exclude": {
        "**/bin": true,
        "**/node_modules": true,
        "**/obj": true
    },
    "csharpfixformat.style.spaces.insideEmptyBraces": false,
    "csharpfixformat.style.braces.allowInlines": false,
    "csharpfixformat.style.spaces.beforeParenthesis": false,
    "csharpfixformat.style.spaces.afterParenthesis": false,
    "csharp.format.enable": false,
    "extensions.ignoreRecommendations": true
}

但是，我不确定如何设置launch.json来启动dotnet test，以便它可以连接调试器。

这是我目前所拥有的：

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "MsTester",
            "type": "coreclr",
            "request": "launch",
            "preLaunchTask": "build",
            "program": "${workspaceFolder}/MsTester/bin/Debug/netcoreapp2.1/MsTester.dll",
            "windows": {
                "args": [
                    "--filter",
                    "TestCategory=lbshell",
                    "--logger",
                    "trx",
                    "--results-directory",
                    ".\\TestResults",
                    "--settings",
                    ".\\Features\\runsettings.xml"
                ],
            },
            "cwd": "${workspaceFolder}/MsTester",
            "console": "internalConsole",
            "stopAtEntry": false,
            "internalConsoleOptions": "openOnSessionStart"
        },
    ]
}

是否可以告诉VS Code它需要执行dotnet test而不是dotnet run？

我希望this page会指示如何执行此操作，但事实并非如此。

这可能不能解决您完全传递参数的问题，但可以解决将runsettings参数传递给要调试的代码的问题。使用这种方法，我可以在运行调试器时（即，当我单击该方法上方的“调试测试”时）将运行设置的内容传递给我的代码：

我最终要做的是：

首先，我编写了一些代码（如果密钥在设置文件中不可用，则将从设置文件（通过TestContext）或用户环境中读取，即：


[ClassInitialize]
public static void TestClassInitialize(TestContext context)
{
    v = Settings.GetSettingValueFromContextOrEnvironment("v", context);
}

这是GetSettingValueFromContextOrEnvironment的实现：

/// <summary>
/// Attempts to read a setting value from the context (populated through runsettings). If the
/// key is not present in the context, the value will be read from the user environment variable
/// instead.
/// 
/// This allows running the unit test code in VSCode debugger that currently doesn't seem to allow
/// passing runsettings file to the DLL.
/// </summary>
/// <param name="name"></param>
/// <param name="context"></param>
/// <returns></returns>
public static String GetSettingValueFromContextOrEnvironment(string name, TestContext context){
    if (context.Properties.ContainsKey(name)){
        return context.Properties[name].ToString();
    } else {
        String envVar = Environment.GetEnvironmentVariable(name, System.EnvironmentVariableTarget.User);

        if (envVar == null){
            throw new Exception(String.Format("Environment variable '{0}' was not available neither in the context file nor in the environment.", name));
        } else {
            return envVar;
        }
    }
}

然后我编写了一个Powershell，它将读取我的设置文件以解析参数并将其设置为用户环境变量，如下所示：

<# This script updates user environment variables with parameters stored in *.runsettings file that is provided to it as the only argument on the command line.

Example usage:
    .\set_settings_env.ps1 local.runsettings
#>

param (
    [Parameter(Mandatory=$true)][string]$settings_file
)


[xml]$xml = Get-Content $settings_file
foreach( $parameter in $xml.RunSettings.TestRunParameters.Parameter) 
{
    write-host("Setting environment variable: " + $parameter.name)
    [Environment]::SetEnvironmentVariable($parameter.name, $parameter.value, "User")
}

所以现在我既可以通过命令行使用特定的runsettings文件运行代码，也可以通过运行脚本设置环境变量来进行调试。

也许这是您正在寻找的更多东西： How does one debug an MSTest in VSCode?

（也请检查注释）。因此，通过使用“ VSTEST_HOST_DEBUG”：“ 1”，您应该能够附加一个调试过程，类似于在Java中的调试过程。
