In a Test-Driven Development (TDD) approach, the primary emphasis is on unit testing. TDD is a software development process in which requirements are turned into specific test cases before software is fully developed. The key process involves writing a test for a new function or feature, running that test (which will fail as the feature is not yet implemented), and then writing the minimum amount of code required to make the test pass. This cycle of writing a test, implementing code, and refactoring is repeated.

Unit testing is particularly relevant in TDD because it focuses on testing the smallest parts of an application in isolation, typically at the level of individual functions or methods. This approach helps developers catch issues early in the development cycle and ensures that each component works as intended before it is integrated with other parts of the system. The focus on unit tests also fosters good design practices, as it encourages developers to create modular and maintainable code.

In contrast, performance testing evaluates how a system performs under certain conditions or loads, integration testing assesses how well different components work together, and user acceptance testing ensures that the software meets the needs and requirements of its end users. While these types of testing are essential in a comprehensive testing strategy, they do not fit the specific
