因果报应和React，警告会导致错误 [英] Karma and React, have warnings to cause errors

问题描述

我正在将业力与 mocha 测试我的反应组件.当PropType不匹配时，我会显示一些警告.但是，让这些警告引起实际错误，以跟踪测试并进行修复，将是非常有趣的.

I am using Karma with mocha to test my React components. I have some warnings displayed when the PropTypes are not matched. However it would be really interesting to have these warnings to cause an actual error, as to track down the test and fix it.

您知道如何实现吗?

推荐答案

您可以使用自己的方法替换console.warn方法，并在提供的消息与特定模式匹配时抛出方法.

You can replace the console.warn method with your own and throw when the message provided matches a certain pattern.

let warn = console.warn;
console.warn = function(warning) {
  if (/(Invalid prop|Failed propType)/.test(warning)) {
    throw new Error(warning);
  }
  warn.apply(console, arguments);
};
