使用 Visual Studio Code 的摩卡断点 [英] Mocha breakpoints using Visual Studio Code

问题描述

是否可以使用 Visual Studio Code 在 Mocha 测试中添加断点?

Is it possible to add breakpoints to Mocha tests using Visual Studio Code?

一般在调试代码时，需要配置launch.json，将program属性设置为Javascript文件来执行.不过，我不确定如何为 Mocha 执行此操作.

Normally when debugging code, one needs to configure the launch.json, setting the program attribute to the Javascript file to execute. I am not sure how to do this for Mocha though.

推荐答案

您知道吗，您只需进入启动配置，将光标放在其他配置之后或之间，然后按 ctrl-space 以获取自动生成的当前有效的 mocha 配置?

Did you know, that you just go into your launch config, put your cursor after or between your other configs and press ctrl-space to get a current, valid mocha config auto-generated?

这对我来说非常好.包括在断点处停止.(我也有一个以前的，现在已经过时的，由于各种与设置相关的原因而不再使用.)

Which works perfectly fine for me. Including stopping at breakpoints. ( I also had a prior, now outdated one, that did no longer for various setting-related reasons. )

从 VSCode 1.21.1(2018 年 3 月)开始，结果如下:

As of VSCode 1.21.1 (March 2018) this yields:

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Mocha (Test single file)",
      "type": "node",
      "request": "launch",
      "runtimeArgs": [
        "${workspaceRoot}/node_modules/.bin/mocha",
        "--inspect-brk",
        "${relativeFile}",
      ],
      "console": "integratedTerminal",
      "internalConsoleOptions": "neverOpen",
      "port": 9229
    }
}

附注:debug-brk 已弃用(至少适用于 Node >= 版本 8 的任何人).

On a side-note: debug-brk is deprectated (for anyone with Node >= Version 8 at least).
