Using TDD and BDD in a Project

Using TDD and BDD in a Project

Top Down Design

• Write BDD Gherkin files to describe the expected functionality of the product. This will give a help level understanding of what a product should do.
• Write low level unit tests for a feature/functionality to drive development following TDD approach.

Bottom Up Implementation

• Develop the feature/functionality using Red-Green-Refactor approach and make all the written tests pass.
• Once the feature/functionality is implemented, write the implementation for the BDD scenarios and check the expected behavior is met.
• Iterate the same for all other features.
