Following the behavior driven development (BDD) methodology thoroughly, one would expect 100% code coverage, since code is only written to make the tests pass. Based on this assumption Melanie and Mathias have investigated BDD-driven projects and found out that this is not the case.
As a consequence, they propose a feature to Cucumber that generates new scenarios based on uncovered code. Applying this feature continuously eventually results in fully covered implementation.
The material presented in the talk was published in M. Diepenbeck, M. Soeken, D. Große and R. Drechsler. Towards Automatic Scenario Generation from Coverage Information, AST, 2013
