如何使用NPM测试进行调试 [英] How to debug with npm test

问题描述

我正在使用VS Code.当我尝试在调试模式下运行测试时，它说describe不是函数.因此，我能够运行测试的唯一方法是通过npm Note.

I am using VS Code. When I try to run the test in debug mode, it says describe is not a function. Thus, only way I am able to run the test is through npm Note.

注意:我正在使用摩卡咖啡和柴.

Note: I am using mocha and chai.

var { describe,it, before, after } = require('mocha');
var assert = require('chai').assert;
var AuthAPI = require('../api/controllers/API.js');
     describe('getItem tests', function() {
    it('getItem ', function(done) {
      var API = new AuthAPI(clientId, PASS, List);

      api_jwt = API.getItem();
      assert.isNotEmpty(api_jwt);
    });
    )}

推荐答案

我认为您仅需要另一种用于Mocha测试的启动配置即可.

I think you just need another launch configuration for your mocha tests.

转到Visual Studio代码中的调试"部分.

Go to Debug section in your Visual Studio Code.

单击选择控件，然后选择添加配置..."(或单击齿轮图标，然后单击添加配置..."按钮)；

Click the select control, then select "Add Configuration..." (or just click the gear icon and then click the "Add Configuration..." button);

您应该可以在此处选择"Node.js:Mocha测试"，它将生成如下启动配置:

You should be able to select "Node.js: Mocha Tests" there, it would generate a launch config like that:

{
    "type": "node",
    "request": "launch",
    "name": "Mocha Tests",
    "program": "${workspaceFolder}/node_modules/mocha/bin/_mocha",
    "args": [
        "-u",
        "tdd",
        "--timeout",
        "999999",
        "--colors",
        "${workspaceFolder}/test"
    ],
    "internalConsoleOptions": "openOnSessionStart"
},

！注意:从mocha 6开始，它需要正确选择接口( https://mochajs.org/#interfaces )，如果要使用describe函数，请将tdd更改为bdd.

确保您的Mocha测试位于./test文件夹中，并且已在本地安装了Mocha或自定义启动程序配置.

!Note: starting from mocha 6 it requires a proper selection of the interface (https://mochajs.org/#interfaces), change tdd to bdd if you want to use describe functions.

Make sure your mocha tests are in ./test folder and you have installed mocha locally or customise the launcher config.

假设您有一个测试./test/it_should_work.js(请注意，它没有任何要求，因为mocha二进制文件本身知道该功能)

Let's say you have a test ./test/it_should_work.js (note, it does not have any require, since mocha binary knows that functions by itself)

describe('test', () => {
  it('should work', () => {
  });
})

启动新创建的摩卡测试"配置，它应该返回成功的结果.

Launch a newly created "Mocha Test" configuration, it should return a successful result.

test
    ✓ should work
  1 passing (9ms)
