如何使用visual studio代码在javascript中调试mocha测试？

如果您使用的是node，则很容易调试：

//.vscode/launch.json
"configurations": [
    {
        "name": "Launch",
        "type": "node",
        "request": "launch",
        ...

但是如果我使用的是mocha测试，我如何调试它呢

我尝试使用：

"configurations": [
    {
        "name": "Launch",
        "type": "mocha",
        "request": "launch",

但这是无效的。有人知道吗

在.vscode/launch.json中创建此新调试目标

{
    "name": "Unit tests",
    "type": "node",
    "program": "${workspaceRoot}/mocha.js",
    "stopOnEntry": true,
    "args": ["${workspaceRoot}/TESTTODEBUG.js"],
    "runtimeExecutable": null,
    "env": {
        "NODE_ENV": "test"
     }

创建文件mocha.js

'use strict';

// Dependencies
var Mocha = require('mocha');

// Determine which tests to run based on argument passed to runner
var args = process.argv.splice(2);
//var args = ["./tests/unit/services/supra-statement.service.test.js"];
var files;



//Define Mocha
var mocha = new Mocha({
  timeout: 60000,
  reporter: 'spec',
  globals: ['Associations', 'CREATE_TEST_WATERLINE', 'DELETE_TEST_WATERLINE']
});

args.forEach(mocha.addFile.bind(mocha));

//Run unit tests
mocha.run(function (failures) {
    process.exit(failures);
});

使用单元测试选项运行调试器
