Test-driven development (TDD) is a software development process where tests are written before the code implementation. The cycle typically involves writing a test case that defines the expected behavior of a feature, running the test (which should fail initially), writing the code to make the test pass, and then refactoring the code to improve its structure while ensuring that the test still passes. This iterative process helps to ensure that the code is functional and remains so, even as it undergoes changes and updates. TDD is valued for its ability to improve code quality, reduce bugs, and provide faster feedback during the development process.
