Everything started with XP
@ua_spring #JugLviv 5
Then comes TDD

What is TDD?

TDD is great, but…
Who will take care of the quality?
@ua_spring #JugLviv 8
What exactly TDD is?
A 2005 study found that using TDD meant writing more tests and, in turn, programmers who wrote more tests tended to be more productive. Hypotheses relating to code quality and a more direct correlation between TDD and productivity were inconclusive.

What exactly TDD is?
Test-driven development offers more than just simple validation of correctness, but can also drive the design of a program

An attempt to fix TDD - ATDD

An attempt to fix TDD - ATDD
Acceptance Test Driven Development (ATDD) is a practice in which the whole team collaboratively discusses acceptance criteria, with examples, and then distills them into a set of concrete acceptance tests before development begins.

An attempt to fix TDD - ATDD
Acceptance TDD helps coordinate software projects in a way that helps us deliver exactly what the customer wants when they want it, and that doesn’t let us implement the required functionality only half way.

What is BDD?
At the heart of BDD is a rethinking of the approach to unit testing and acceptance testing: unit test names are whole sentences starting with the word "should" and they are written in order of business value.
BDD encourages collaboration among developers, QA and non-technical or business participants in a software project. It has evolved over the last few years.

BDD + Selenium
Concordion is an open source tool for writing automated acceptance tests in Java*
* There are also versions for .NET, Python, Scala, and Ruby.

Alternatives: platform
Be pragmatic – don’t use Java where it is not needed.

Alternatives: BDD frameworks

Alternatives: UI tests
@ua_spring #JugLviv 22
Approach criticism
Often “pure BDD” is not needed - ATDD is enough
Usually UI-tests are better to replace with lower-level tests (e.g. integration or even functional)
@ua_spring #JugLviv 23
Conclusion
@ua_spring #JugLviv 24
Talking seriously…
BDD is designed for a projects where business and engineering are working tightly
BDD is not useful for every project
BDD adoption is a complex process
every team member is responsible for a product quality
