nGrinder实现多接口性能测试

本文档展示了如何使用Grinder进行接口性能测试,特别是针对发送feed和回复feed的场景。代码示例中,详细说明了如何配置Header、Cookie,并进行请求参数化,同时提供了测试场景的运行率。测试过程中,首先发送feed并获取feedID,然后利用feedID进行回复操作,整个过程都在JUnit测试框架下进行。

       如果要对多接口进行性能测试,每个接口都需要监控指标,就需要针对每个接口建立测试场景,即@Test注解。

       下文的示例是在Cookie指定的情况下,完成发送feed(类似微博的一种卡片信息)和在feed下回复。发feed生成了feedID,根据feedID去回复。一些敏感信息使用了XXXXX来代替,可以自行修改。
