Welcome to another important module in this course, testing react apps. Now with testing here,
I don't mean us manually clicking around in our application,
we already do that constantly while developing it. With testing here,
I mean writing automated tests and now here is something important which I want to mention right at
the start of this module, testing is a complex topic and is actually a huge enough topic to make up an
entire course just on its own.
This is not a testing in general introduction and it's also not a complete react testing guidelike
module.
Instead I will introduce you into writing unit tests for react applications built with create react
app and that can then be something you build up on or which helps you apply your general javascript
testing knowledge you already have or gathering other resources.
With that out of the way, let's dive into what testing exactly is in the next lecture and then learn
how we can write tests for our react application.
