BDD Extension Framework for Unity Test Tools lets you develop your software using BDD.
It is fully integrated with the standard Unity Test Tools: you can use the tests created with the BDD Extension Framework as a regular Unity Test Tools Integration Test.
Boost your game and app development creating Behaviour Driven Development scenarios directly from the Unity Editor.
Standardise your Acceptance Criteria and Acceptance Tests using the Given - When - Then format.
Read the complete scenario via inspector and test result.
Reuse your test code.
Compose your integration tests dynamically.
If you are into continuous integration, you can run your tests in batch mode: relevant information in the output will guide you in case of test failure.
