So you have tests, they are well named, well structured, with given, when, then blocks and all that beautiful things, they can even fit on a screen! But do you know how and what part of your code these tests test?
Last time I wrote a bit about the importance of testing your code. This time I’ll focus more on what test has to have.
Probably every developer will agree that testing software is important, everyone expects from third-party library or application that it will work, that it is well written and thoroughly tested, even if it’s free and you do not have to pay for it. So if everyone agrees, why so many developers don’t test their code?
