That's really easy to test software if you have a full set of requirements for it. But what if not?
Usually, there is no enough documentation, and a tester has to investigate a lot before starting real testing:

* Which data is positive and negative?
* How our customers use the product?
* Which important information an analyst forgot to put into the documentation?
We will learn how to make software models and ask proper questions to gather all the information needed.
