<p>其实 Jest 也可以去写插件，但并没有现成的 Ajax 相关的 Jest 插件，但是 Jest 测试中我们仍然可以使用 Jasmine 相关的插件，只需要做一些小小的配置即可。</p> <p>当然，未来我也会考虑去编写一个 Ajax 相关的 Jest 插件，目前我们仍然使用 <code>jasmine-ajax</code> 去配合我们编写测试。</p> <p><code>jasmine-ajax</code> 依赖 <code>jasmine-core</code>，因此首先我们要安装几个依赖包，<code>jasmine-ajax</code>、<code>jasmine-core</code> 和 <code>@types/jasmine-ajax</code>。</p> <p>这个时候我们需要去修改 <code>test/boot.ts</code> 文件，因为每次跑具体测试代码之前会先运行该文件，我们可以在这里去初始化 <code>jasmine-ajax</code>。</p> <div class="language-typescript line-numbers-mode"><pre class="language-typescript"><code><span

<code>jasmine.Ajax.requests.mostRecent()</code> 拿到最近一次请求的 <code>request</code> 对象，这个 <code>request</code> 对象是 <code>jasmine-ajax</code> 库伪造的 <code>xhr</code> 对象，它模拟了 <code>xhr</code> 对象上的方法，并且提供一些

种解决方案。</p> <p>第一种是利用 <code>done</code> 参数，每个测试用例函数有一个 <code>done</code> 参数，一旦我们使用了该参数，只有当 <code>done</code> 函数执行的时候表示这个测试用例结束。</p> <p>第二种是我们的测试函数返回一个 Promise 对象，一旦这个 Promise 对象 <code>resolve</code> 了，表示这个测试结束。</p> <ul><li>expect.any(constructor)</li></ul> <p>它表示匹配任意由 <code>constructor</code> 创建的对象实例。</p> <ul><li><code>request.eventBus.trigger</code></li></ul> <p>由于 <code>request.responseTimeout</code> 方法内部依赖了 <code>jasmine.clock</code> 方法会导致运行失败，这里我直接用了 <code>request.eventBus.trigger('timeout')</code> 方法触发了 <code>timeout</code> 事件。因为这个方法不在接口定义中，所以需要加 <code>// @ts-ignore</code>。</p> <p>另外，我们在测试中发现 2 个 case 没有通过。</p> <p>第一个是 <code>should treat method value as lowercase string</code>，这个测试用例是我们发送请求的 <code>method</code> 需要转换成小写字符串，这么做的目的也是为了之后 <code>flattenHeaders</code> 能正常处理这些 <code>method</code>，所以我们需要修改源码逻辑。</p> <p><code>core/Axios.ts</code>：</p> <div class="language-typescript line-numbers-mode"><pre class="language-typescript"><code>
