javascript – 使用Karma运行的Mocha单元测试

我正在尝试用Mocha编写测试来运行Karma,它们有点工作,但是我不能使用done()方法来实现异步测试,这实际上使得这些工具对我来说毫无用处.我错过了什么？

karma.conf.js

module.exports = function(config) {
  config.set({
    basePath: '../..',frameworks: ['mocha','requirejs','qunit'],client: {
        mocha: {
            ui: 'bdd'
        }
    },files: [
      {pattern: 'libs/**/*.js',included: false},{pattern: 'src/**/*.js',{pattern: 'tests/mocha/mocha.js',{pattern: 'tests/should/should.js',{pattern: 'tests/**/*Spec.js','tests/karma/test-main.js'
    ],exclude: [
      'src/main.js'
    ],// test results reporter to use
    // possible values: 'dots','progress','junit','growl','coverage'
    reporters: ['progress','dots'],port: 9876,colors: true,// possible values: config.LOG_DISABLE || config.LOG_ERROR || config.LOG_WARN || config.LOG_INFO || config.LOG_DEBUG
    logLevel: config.LOG_WARN,autoWatch: true,// Start these browsers,currently available:
    // - Chrome
    // - ChromeCanary
    // - Firefox
    // - Opera (has to be installed with `npm install karma-opera-launcher`)
    // - Safari (only Mac; has to be installed with `npm install karma-safari-launcher`)
    // - PhantomJS
    // - IE (only Windows; has to be installed with `npm install karma-ie-launcher`)
    browsers: ['Chrome'],// If browser does not capture in given timeout [ms],kill it
    captureTimeout: 60000,// Continuous Integration mode
    // if true,it capture browsers,run tests and exit
    singleRun: false
  });
};

test-main.js(配置RequireJS)

var allTestFiles = [];
var pathToModule = function(path) {
  return path.replace(/^\/base\//,'../').replace(/\.js$/,'');
};

Object.keys(window.__karma__.files).forEach(function(file) {
  if (/Spec\.js$/.test(file)) {
    // Normalize paths to RequireJS module names.
    allTestFiles.push(pathToModule(file));
  }
});

require.config({
  // Karma serves files under /base,which is the basePath from your config file
  baseUrl: '/base/src',paths: {
    'should': '../tests/should/should','mocha': '../tests/mocha/mocha','pubsub': '../libs/pubsub/pubsub','jquery': '../libs/jquery/jquery-1.10.2','jquery-mobile': '//code.jquery.com/mobile/1.4.2/jquery.mobile-1.4.2.min'
  },// dynamically load all test files
  deps: allTestFiles,// we have to kickoff jasmine,as it is asynchronous
  callback: window.__karma__.start
});

测试/ fooSpec.js

define(['music/note'],function(Note) {

describe('nothing',function(done) {
    it('a silly test',function() {
        var note = new Note;
        note.should.not.eql(32);
    });
    done();
});
...

虽然这是一个人为的例子,但如果我删除done()调用它会成功.事实上,我得到：

Uncaught TypeError: undefined is not a function
at /Library/WebServer/Documents/vg/tests/mocha/fooSpec.js:8

这是done()行.如何/为什么没有定义？我不知道在哪里配置Mocha(或使用什么选项).是否存在某种全局命名空间或元编程魔法导致RequireJS干扰Mocha？

我正在OS X 10.9.2上的Chrome 33中运行测试,如果完全相关的话.我已经花了很多时间在这上面并准备放弃自动化测试:( – 有类似的砖墙与QUnit / Karma / RequireJS,并且无法找到任何替代成功自动化测试.我感觉像一个白痴.

解决方法

在Mocha中,完成回调是针对它的,之前,之后,之后是每个.所以：

describe('nothing',function() {
    it('a silly test',function(done) {
        var note = new Note;
        note.should.not.eql(32);
        done();
    });
});

这是doc.
