为什么不将包含在React模块上的模拟事件触发为依赖项？

Question

我正在将一个大型React项目（https://github.com/bootstrapworld/codemirror-blocks）重构为模块，一个核心库，该核心库由其他模块（例如-https://github.com/bootstrapworld/pyret-blocks）包含和扩展。

我在整体仓库中有一个大型测试套件，可以通过。在重构设置中，当这些相同的测试包含模拟的（通过React-TestUtils）按键事件时，它们将失败。

一些调试表明，核心库根本没有收到这些事件。事件处理程序根本根本不会被调用。但是，运行实际的应用程序效果很好，所有真实事件都可以正确处理。

没有任何错误消息-Karma测试只是失败，没有输出（Karma测试失败除外）：
