Karma和Jasmine：测试不识别任何茉莉花功能

Question

我把茉莉花与我的gulp，karma，browserify等配置集成在一起，但对于我的生活，我无法弄清楚为什么没有定义茉莉花功能：

TypeError: expect(...).toEqual is not a function

我能找到的所有样本都要求karma.conf.js添加“jasmine”作为框架，我应该好好去。

这是我的karma.conf.js：

module.exports = function(config) {
  config.set({

    // base path that will be used to resolve all patterns (eg. files, exclude)
    basePath: '',

    // frameworks to use
    // available frameworks: https://npmjs.org/browse/keyword/karma-adapter
    frameworks: ['jasmine', 'mocha', 'sinon-chai', 'browserify'],

    // list of files / patterns to load in the browser
    files: [
      'src/js/**/__tests__/*'
    ],

    // list of files to exclude
    exclude: [
    ],

    // preprocess matching files before serving them to the browser
    // available preprocessors: https://npmjs.org/browse/keyword/karma-preprocessor
    preprocessors: {
      'src/js/**/__tests__/*': ['browserify']
    },

    browserify: {
        debug: true,
        extensions: ['.js', '.coffee', '.hbs']
    },

    // test results reporter to use
    // possible values: 'dots', 'progress'
    // available reporters: https://npmjs.org/browse/keyword/karma-reporter
    reporters: ['nyan'],

    // web server port
    port: 9876,

    // enable / disable colors in the output (reporters and logs)
    colors: true,

    // level of logging
    // possible values: config.LOG_DISABLE || config.LOG_ERROR || config.LOG_WARN || config.LOG_INFO || config.LOG_DEBUG
    logLevel: config.LOG_INFO,

    // enable / disable watching file and executing tests whenever any file changes
    autoWatch: true,

    // start these browsers
    // available browser launchers: https://npmjs.org/browse/keyword/karma-launcher
    browsers: ['Chrome'],

    // Continuous Integration mode
    // if true, Karma captures browsers, runs the tests and exits
    singleRun: false,

    // Helps to address an issue on TravisCI where activity can time out
    browserNoActivityTimeout: 30000
  });
};

简单的演示测试：

var $ = require('jquery');
var locator = require('../modules/locator.js');

describe('modules/locator.js', function () {
    it('should equal hello', function () {
        expect(locator).toEqual('hello');
    });
});

失败，因为无法识别expect（...）。toEqual（..）作为函数。或者，非jasmine语法可以正常传递：

var $ = require('jquery');
var locator = require('../modules/locator.js');

describe('modules/locator.js', function () {
    return it('should equal hello', function () {
        return locator.should.equal('hello');
    });
});
