我正在努力创造我自己的 bootstrap project .目前我完成了很多事情，但现在我遇到了 ReactJS 组件单元测试的问题。
当我在浏览器中运行应用程序时 - 一切正常。我使用 RequireJS 来延迟加载所需的模块。包装到 RequireJS 模块中的 React 组件和浏览器中的一切都按预期工作。
但是当我尝试对 React 组件进行单元测试时，RequireJs 不会加载 React。 React 是未定义的...
这是 Gruntfile.js ，我在其中创建 karma 任务。
这里是 karma.config.js带有 karma 配置的文件。
这是 test-main.js这是运行测试。
我的测试文件如下所示:
define(['helper/utils', 'underscore', 'components/List'], function(utils, _, List){
describe("First test for example", function() {
it("TRUE should be TRUE :)", function() {
expect(true).toBe(true);
});
it("Test requirejs helper loading", function(){
expect(utils.testJasmine()).toBe("Jasmine");
});
it('Underscore is works', function() {
// just checking that _ works
expect(_.size([1,2,3])).toEqual(3);
});
it('List component is loaded', function(){
expect(List.test()).toBe('List Component');
});
});
});
List - 这是我的 ReactJS 组件。当我尝试运行我的测试时，我收到了错误结果:

最佳答案
ReactJS 与 PhantomJS 有问题 https://github.com/facebook/react/pull/347
这是一个修复:
加载 https://github.com/facebook/react/blob/3dc10749080a460e48bee46d769763ec7191ac76/src/test/phantomjs-shims.js 文件。
将 karma.config.js 添加到 files
'scripts/phantomjs-shims.js',
关于javascript - React 组件在 RequireJS+Jasmine 单元测试中不起作用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/34290347/
