Test-driven development
Test-driven development, commonly abbreviated as TDD, is a modern software development approach that has revolutionized the way code is written and tested. At its core, TDD inverts traditional development methodologies by advocating for the creation of tests before the development of the actual functional code. This paradigm shift is encapsulated in a cyclic process known as “Red-Green-Refactor.” Initially, a developer writes a test that defines a desired improvement or a new function, which inevitably fails on the first run – this is the “Red” phase, indicating the absence of the corresponding functionality. Subsequently, in the “Green” phase, the developer crafts the minimum amount of code necessary to pass the test, thereby ensuring that the functionality meets the specified requirements. The cycle culminates in the “Refactor” phase, where the new code is refined and optimized without altering...
