我正在尝试在我的 React 站点上使用 Karma 运行 Jasmine 测试。我的测试之前一直在工作，我不确定发生了什么变化，但现在我收到错误消息：
Uncaught ReferenceError: require is not defined
对于 Chrome 和 PhantomJS 以及 Firefox 给我类似的错误。如果更多信息有帮助，请告诉我。我在网上发现了很多类似的问题，但都没有解决问题。
你可以看到下面的测试文件，完整的项目在我的 github repo 上。
提前致谢！
我的测试文件如下所示：
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');
});
});我的 karma.conf.js 文件如下所示：

config.set({

};这是我在进行@guilhebl 推荐的更改后得到的错误：
