TDD vs BDD: Full Comparison
TDD (Test Driven Development) and BDD (Behavior Driven Development) are fairly similar development approaches that both emphasize testing and collaboration, yet have major differences in focus and methodology. Simply put, in TDD, developers test first, then use the test results to guide their development, while in BDD, developers express the system behavior they want to create through Gherkin syntax, then code according to those Gherkin expressions.
