  We’ll need an Angular application to test, one as simple as possible while having most of the angular features we want to test.

  我们首先得有一个待测试的Angular应用程序，一个尽可能简单，但几乎拥有所有待测Angular特性的应用程序。

  What better app than our own [The Tour of Heroes](../tutorial/toh-pt5.html)? We're already quite familiar with it and it fits our criteria, so let's try to test what we've done there.

  还有什么会比我们自己做的[英雄指南](../tutorial/toh-pt5.html)更合适呢？我们已经很熟悉它了，它也挺适合我们的课程目标，那就来测试一下我们已经完成的那些功能吧。

  We might end up modifying it a bit, because it doesn't have everything we want to test, but it's the perfect starting point.

  我们可能需要对它做一些修改，因为它还没有覆盖我们要测试的所有东西，但是它是一个完美的起点。

  Create a copy of the Tour of Heroes app so that we can fiddle without fear.

  先复制一份《英雄指南》的源码，这样我们就可以肆无忌惮的摆弄它了。
