Stages of the TDD approach

[sumaiyakhatun26]

Before any new code is written, the programmer must first create a failing unit test. Then, the programmer - or a couple, or a bunch - creates enough code to satisfy that requirement. Once the test passes, the programmer can refactor the project, making improvements without changing the behavior.

While TDD focuses on unit-level programmer interactions, there are other popular methods, south korea rcs data such as acceptance test-driven development (ATDD) or behavior-driven development (BDD), which focus on tests that are understandable by customers.


These methods involve creating real-world examples as collaborative tests between engineering staff and the customer before coding, and running tests after coding to demonstrate that the code is implemented. Knowing the tests in advance improves first-time quality. ATDD and BDD require developers, testers, and the business side to work together to envision and discuss the software and its implications before code is created.
