我正在使用Karma和Jasmine对使用React构建的项目进行测试。当我尝试运行我的Karma测试时，我在控制台中收到此错误：
binary scan我已尝试http://requirejs.org/docs/errors.html#notloaded处的建议，但未改变错误。我也尝试将我的require语句变成一个大的回调地狱，但它没有解决问题。我确定问题是它在加载模块之前尝试运行测试，但是如果我不能让它等待使用回调，我不知道如何处理这个问题。任何帮助将不胜感激，提前致谢。
我将在下面粘贴我的karma.conf.js，story_test.js和test_entry.js文件。如果有更多信息可以提供帮助，请告诉我。您可以在my GitHub Repo上查看完整项目。
这是我的karam.conf.js：

这是我的story_test.js：

config.set({

};
最后这里是test_entry.js：
'use strict';
var React = require('react/addons');
var Story = require('../../app/js/components/story.jsx');
var TestUtils = React.addons.TestUtils;
var testUtilsAdditions = require('react-testutils-additions');
describe('Story component', function () {
var component;
beforeEach(function () {
var element = React.createElement(Story);
element.props.data = {
storyTitle: 'front end test title',
author : 'front end author',
storyText : 'front end story text'
};
component = TestUtils.renderIntoDocument(element);
});
it('should display a story', function () {
expect(component.props.data).toBeDefined();
expect(component.props.data.storyTitle).toBeDefined();
expect(component.props.data.storyTitle).toBe('front end test title');
expect(component.props.data.author).toBe('front end author');
expect(component.props.data.storyText).toBe('front end story text');
});
});
答案 0 :(得分：0)
该错误似乎来自http://requirejs.org项目，我认为是试图让您改变使用同步CommonJS需求调用，例如;
require('./simple_test.js');
require('./story_test.js');
到异步AMD调用，例如;
require(['./simple_test.js', './story_test.js'], function() {
// simple_test and story_test are now loaded
});
我不清楚你发布的是哪些模块是requirejs / AMD，哪些不是，看起来你可能会混淆两者？对不起，我的帮助不止于此。
