javascript – Jasmine测试给出错误“Uncaught ReferenceError：require not not defined”
作者：互联网
我想在我的React网站上用Karma运行Jasmine测试.我之前的测试工作正常,我不确定发生了什么变化,但现在我收到了错误：
未捕获的ReferenceError：未定义require
Chrome和PhantomJS和Firefox给我类似的错误.如果有更多信息可以提供帮助,请与我们联系.我在网上发现了很多类似的问题,但没有解决问题的方法.
您可以在下面看到测试文件,整个项目在my 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：
// Karma configuration

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

};这是我在推荐更改@guilhebl后得到的错误：
Firefox 40.0.0 (Ubuntu 0.0.0) ERROR

这是我做出更改后的karma.conf.js：

};解决方法:
您应该在karma.conf文件中配置require,例如：
module.exports = function(config){
config.set({
frameworks: ['jasmine'],
plugins : [
'karma-chrome-launcher',
'karma-firefox-launcher',
'karma-script-launcher',
'karma-phantomjs-launcher',
'karma-jasmine',
'karma-requirejs'
],
files : [
'node_modules/requirejs/require.js',
'node_modules/karma-requirejs/lib/adapter.js',
'app/js/test-main.js',
{pattern: 'app/lib/**/*.js', included: false},
{pattern: 'app/js/**/*.js', included: false},
{pattern: 'app/js/views/**/*Test.js', included: false}
],
browsers: ['PhantomJS']
});
};
