TDD & BDD Methodologies

Write tests before code. Master Test Driven Development (TDD) and Behavior Driven Development (BDD) using Cucumber and Gherkin.

Quality should be baked in, not inspected in. This course teaches the methodologies of TDD and BDD. You will learn the 'Red-Green-Refactor' cycle of TDD to write cleaner code. Then, master BDD using Cucumber and Gherkin syntax ('Given-When-Then') to create executable specifications that non-technical stakeholders can read. This bridges the communication gap between Product, Dev, and QA, creating 'Living Documentation'.
