Reading list: What is Test Driven Development (TDD) and How Does It Improve Code Quality?
Test Driven Development (TDD) is a software development methodology where tests are written before the actual code. The process follows a short, repetitive cycle of writing a test, implementing the code to pass that test, and then refactoring the code. This approach helps to ensure that each unit of functionality meets specific requirements and works as expected, leading to a higher-quality codebase.

Here’s how TDD improves code quality:

Early Detection of Bugs: Since tests are written before the code, developers can immediately identify and fix bugs during the coding process, rather than at the end.

Enhanced Code Coverage: TDD ensures that every part of the application is tested, which improves the overall test coverage and ensures no areas are left untested.

Faster Debugging: With tests in place, pinpointing the source of issues becomes easier, as the tests are tied directly to each feature or unit of code.

Modular, Maintainable Code: TDD promotes writing small, modular units of code, which leads to more maintainable software. Refactoring becomes safer since you always have a set of tests to verify that the code still works as expected after changes.

Improved Confidence: With a comprehensive set of tests running consistently, developers can be confident that the system is working correctly. This leads to fewer bugs, especially when adding new features or modifying existing code.

In conclusion, TDD leads to fewer bugs and higher-quality software by encouraging rigorous testing practices, improving code reliability, and providing early feedback throughout the development cycle.
