QA Mock System

对于测试者来说,最最重要的事就是为产品按质按量上线提供保驾护航,把好最后一关。那测试中我们会有哪些测试手段呢?功能测试,接口测试和性能测试等,不管使用哪种测试手段都离不开测试数据,而测试数据的丰富程度决定测试覆盖情况,因而决定对产品质量把关的程度。这个对于我们测试者,大家都知道,那怎么能把这个测试数据准备的丰富,能高效地创建和管理这些数据呢,特别是对自动化来说,测试的稳定性非常重要,而往往导致不稳定的主要的因素就是测试数据的不稳定。一说到稳定的测试数据,大家可能都会想到造数据,或者mock数据,但对于上层服务的测试,因为依赖的服务很多,耦合性强,通过去造这么一份数据,是非常痛苦的事,就像一块坚厚的冰块挡在我们前进的道路上,我们必须绕着走,这条路可能会弯弯曲曲,非常的费事费力。那接下来我们一起来看看在Coupang我们怎么来一步步把这块冰块凿破,打通一条快速通道。
