Add a Testing structure proposal in testing section

[avitsidis]

It could be a good idea to add a test structure proposal in the testing section. I was thinking to something like the phil haacked proposition : name test class like {Class}Test, create sub test classes with method name and then name test with the expectedResult.

I can write a pull request with an implementation inspired from phil haacked pattern (https://haacked.com/archive/2012/01/02/structuring-unit-tests.aspx/)
