Unit testing style

There are plenty of books that talk about software testing in terms of design principles and development processes (for example, Test Driven Development). This book, on the other hand, is a sort of hands-on manual that tries to explain the fundamental patterns, technologies, and tools involved in web application testing. This means that the main objective here is not to discuss the big picture of software testing; however, every unit testing framework is inspired by a specific style, so we need to briefly talk about it.

One of the most known techniques about testing is TDD or Test Driven Development, but it is a mistake to think that TDD is simply related to unit testing. TDD is a software development process that pursues a good code design using unit testing as a means to reach its objective.
