npm 插件安装

全局npm安装插件

npm install -g grunt-cli 
npm install -g gulp

另外项目需要添加如下依赖 package.json

"dependencies": {
    "assert": "^1.4.1",
    "express": "^4.15.4",
    "mysql": "^2.14.1"
  },
  "devDependencies": {
    "chai": "^4.1.1",
    "chai-as-promised": "^7.1.1",
    "grunt": "^1.0.1",
    "grunt-mocha": "^1.0.4",
    "grunt-mocha-cli": "^3.0.0",
    "grunt-mocha-test": "^0.13.2",
    "gulp": "^3.9.1",
    "gulp-cli": "^1.4.0",
    "gulp-concat": "^2.6.1",
    "gulp-mocha": "^4.3.1",
    "gulp-notify": "^3.0.0",
    "gulp-rename": "^1.2.2",
    "gulp-uglify": "^3.0.0",
    "istanbul": "^0.4.5",
    "load-grunt-tasks": "^3.5.2",
    "mocha": "^3.5.0",
    "should": "^11.2.1",
    "sinon": "^3.2.1",
    "supertest": "^3.0.0"
  }

mocha 单元测试

基本测试 test-demo.js

var assert = require('assert');
var request = require('supertest');
var assert = require("assert");
describe('Array', function() {  
  describe('#indexOf()', function() {
    it('should return -1 when the value is not present', function(done){
      assert.equal(-1, [1,2,3].indexOf(5));
      assert.equal(-1, [1,2,3].indexOf(0));
      done();
    });
  });
});

使用supertest 进行接口测试 test-webapi.js

var assert = require('assert');
var request = require('supertest');

describe('Routing', function() {
  var url = process.env.TESTURL || 'http://localhost:3000';
  var userCookie = '';

  before(function(done) {
   done();
  });

  describe('#a', function() {
    it('', function(done){
     //发送数据
    //   var profile = {
    //     email: 'xuyawenwen',
    //     password: '123456',
    //   };
      request(url)
        .get('/a')
        //.send(profile)
        .expect(200) //Status code   期望
        .end(function(err,res) {
          if (err) {
            throw err;
          }
        //   console.log(res)
          console.log("success res==>",res.text);
          done();
        });

    });
  });

});

这时候执行如下命令就可以进行单元测试了

mocha test/test-demo.js

#注意接口测试要先把接口项目跑起来
mocha test/test-webapi.js

mocha 与gulp 集成

项目中添加gulpfile.js

var gulp = require('gulp');
var mocha = require('gulp-mocha');
gulp.task('default', function() {
  return gulp.src(['test/test-*.js'], { read: false })
    .pipe(mocha({
      reporter: 'spec',
      globals: {
        should: require('should')
      }
    }));
});

mocha 与grunt集成

项目中添加Gruntfile.js

module.exports = function(grunt) {
      grunt.initConfig({
        pkg: grunt.file.readJSON('package.json'),
        mochaTest: {
            src: ['test/test-*.js'],
            options: {
                timeout: 6000,
                reporter: 'spec'
            }
          }
      });
      grunt.loadNpmTasks('grunt-mocha-test');
      grunt.registerTask('default', ['mochaTest']);    
};
