严重的时候甚至会出现我改了一行代码,却不清楚其影响范围情况。这种时候,就需要测试的方式,来保障我们应用的质量和稳定性了。 接下来,让我们学习下,如何给React应用写单元测试吧? 需要什么样的测试 软件测试是有级别的,下面是《Google软件测试之道》一书中,对于测试认证级别的定义,摘录如下: •级别1 •使用测试...

(that's the goal) React-Hot-Loader would not change the past, only update the present - no lifecycle event would be called on component update. As a result, any code changes made tocomponentWillUnmountorcomponentDidMountwould be ignored for already created components. ...
Imagine you are going to lazy-load an image you have already loaded in the same page. In that case, there is no need to lazy-load it because it's already stored in the cache of the user's browser. You can directly display it. ...
