Test-driven development
Test Driven Development (TDD) is a software development approach where test cases are developed to specify and validate what the code will do.
Test cases are created and tested for virtually every feature before the software is released, and if the test fails, new code is written (or rewritten or patched) to pass the test and make the code smooth and bug-free.

Test Driven Development (TDD) begins with the design and development of tests for south korea rcs data every small feature in an application. The TDD framework instructs developers to write new code if automated tests fail. This approach avoids code duplication. A complete TDD module is test-driven development.

Test Driven Development (TDD) originated as part of a larger software design paradigm known as Extreme Programming (XP), which is part of the Agile software development methodology.

The simple concept of TDD is to write and fix failing tests before writing new code (before development). This helps avoid code duplication as we write small amounts of code at a time to pass the tests. (Tests are nothing more than requirement conditions that we have to test to satisfy).

Test-driven development is the process of developing and running automated tests before the actual development of the application. Hence, TDD is sometimes also called test first development.
