Test Driven Development (TDD) involves developers writing tests before coding to ensure quality from the start, focusing on code correctness and maintainability. Software Testers primarily execute and design tests to identify bugs and verify features. While TDD is integrated into the development process, Software Testers focus on validation and quality assurance. Both roles are essential for delivering reliable software but differ in their approach and responsibilities.
