There is one problem. In many different sources, we have discrepancies regards to those terms. I will show you my understanding of this topic. Of course, based on chosen sources.

Some time ago, I was participating in an Instagram challenge called #30devstories. During that challenge, I create a lot of nice and short materials related to programming. I would like to share them with you using a more permanent way then InstaStory. I will start with TDD - Test Driven Development. In more details, I described this topic in the article TDD - Basics. Today I will focus only on a very short introduction to TDD.

When it comes to programming I always think about the quality. And when we talk about quality, we need to mention testing. Testing software is very important. This is for me so natural, so transparent that almost obvious. I realized that this isn’t obvious to everyone on one of my presentations. I asked the audience about testing and I have already known, that I need to talk about testing more. When I write a code, I also write tests, but I do that in reverse order. First, I write a test, then the code. This are for me two elements...
