A roadmap to BDD
What is the right granularity for a BDD test? This is an important question that I will try to answer in this section.
BDD versus integration testing
There are several misconceptions about BDD, but the most popular one is that BDD implies an integration test of most of the layers of the system. This is actually not true, and it results from a naïve approach to BDD. It is not uncommon to see BDD suites that drive the UI and perform the setup against the DB and the assertion phase using both the UI and the DB. This is not a really good approach, because it results in brittle and slow tests and BDD specifications that try to address all the problem domains at the same time.
A good BDD test suite has the following properties:
