What is TDD (Test Driven Development) | How to Implement TDD

Welcome to my RUclips channel, In this video, I have explained TDD ( Test-Driven Development). It's a software development process where tests are written before the actual code. The TDD cycle typically follows these steps:
Write a test: First, a developer writes a test that defines the desired behavior of a small piece of code.
Run the test: The developer runs the test to ensure that it fails. This is because the code being tested doesn't exist yet or doesn't satisfy the test conditions.
Write the code: Next, the developer writes the minimum amount of code necessary to pass the test.
Refactor: If necessary, the developer refactors the code to improve its structure, readability, or performance without changing its functionality.
Benefits of TDD include:
a. Ensuring that all parts of the codebase are covered by tests.
b. Providing immediate feedback on the correctness of the code.
c. Encouraging modular, testable, and maintainable code.
d. TDD is widely used in agile and iterative development methodologies to improve code quality and reduce bugs by catching them early in development.
