在 VSCode 中调试 Java 单元测试

Question

我试图在运行 JUnit 测试时调试一个类，但是，我的配置似乎不正确：

tasks.json

{
  "version": "2.0.0",
  "tasks": [
    {
      "label": "Maven: compile",
      "type": "shell",
      "command": "mvn",
      "args": ["compile"],
      "group": {
        "kind": "build",
        "isDefault": true
      },
      "problemMatcher": ["$maven"],
      "detail": "Compile the project using Maven"
    },
    {
      "label": "Maven: test",
      "type": "shell",
      "command": "mvn",
      "args": ["test"],
      "group": {
        "kind": "test",
        "isDefault": true
      },
      "problemMatcher": ["$maven"],
      "dependsOn": "Maven: compile",
      "detail": "Run all tests using Maven"
    },
    {
      "label": "Maven: test XodusDatabaseTest",
      "type": "shell",
      "command": "mvn",
      "args": ["compile", "test", "-Dtest=XodusDatabaseTest"],
      "group": {
        "kind": "test",
        "isDefault": true
      },
      "problemMatcher": ["$maven"],
      "detail": "Run XodusDatabaseTest using Maven"
    },
    {
      "label": "Maven: debug XodusDatabaseTest",
      "type": "shell",
      "command": "mvn",
      "args": [
        "compile", 
        "test",
        "-Dtest=XodusDatabaseTest",
        "-Dmaven.surefire.debug"
      ],
      "problemMatcher": ["$maven"],
      "detail": "Debug XodusDatabaseTest using Maven"
    }
  ]
}

launch.json

{
  "version": "0.2.0",
  "configurations": [
    {
      "type": "java",
      "name": "Debug Test XodusDatabaseTest",
      "request": "launch",
      "mainClass": "",
      "preLaunchTask": "Maven: debug XodusDatabaseTest",
      "cwd": "${workspaceFolder}",
      "vmArgs": "-Dfile.encoding=UTF-8",
      "console": "integratedTerminal",
      "debugServer": 5005 
    }
  ]
}

运行“调试测试...”卡住等待调试器：

-------------------------------------------------------
 T E S T S
-------------------------------------------------------
Listening for transport dt_socket at address: 5005

我希望它继续进行单元测试并在 VScode 中设置的任何断点处停止。

您可以尝试将

"mainClass": "your main class name"

添加到

launch.json

文件中。另外，您还可以使用

win+R

输入

cmd

，然后用命令输入

netstat -ano | findstr 5005

。检查端口是否被占用。如果被占用，可以打开资源管理器查看被占用的进程是否为关键进程。关闭并重试。您可以查看 Java debugging 和 testing 的文档。
