Whether you're building a microservice architecture, a web application, or a legacy modernization project, TDD and BDD offer powerful lenses through which to view software development. They help ensure not only that your software works, but that it does so in ways that are testable, understandable, and aligned with user needs. So the next time your team asks what is TDD and BDD and which path to follow, remember: the goal isn’t to pick one and reject the other. The goal is to understand both, know where they fit, and apply them purposefully. https://testomat.io/blog/exploring-tdd-vs-bdd-which-is-right-for-you/
