There is nothing that complements the Programmer's Mind more than fine-tuning your programs and systems. But developing the Tester Mind is not necessarily linked to being a Programmer, just as you don't have to be a criminal to be a detective. In fact, testing and tuning can and should be the Tester's video game of choice. Adrenaline is wasted testing and fixing, perhaps more than programming.

Testing is possibly more complex than Programming, since many factors and even unexpected events will have to be taken into account in order to decide if a Program or System is ready for the work for which it was intended. That is why it is very important to develop a varied type of Brain Graphs before starting to test, where without ambiguity and without so much precision we make our short-term intentions very clear with each test, the tools that we will use, those that we will have to develop, etc. .

In this part of the course we will go step by step trying to create a Tester Mind for you, from the simplest to the most complex.
