TDD vs BDD – What’s the Difference Between TDD and BDD?

Test-driven development (TDD) and behavior-driven development (BDD) are methodologies used in software development to enhance code quality and maintainability, though they differ in focus and implementation. TDD involves writing tests before code to reduce bugs and improve maintainability, with developers frequently running automated tests to track progress. In contrast, BDD emphasizes understanding software behavior from a user's perspective, using collaborative efforts to create user stories often written in Gherkin syntax. While TDD is typically executed by developers in isolation, BDD involves collaboration among product owners, business analysts, developers, and QA teams. The article highlights testRigor as a tool that enhances BDD by allowing the creation of executable specifications in plain English, simplifying the process and addressing some limitations of traditional BDD, thereby optimizing resources and streamlining software development.
