Description: Test implementation is a fundamental process in test-driven development (TDD), which involves executing predefined test cases and recording the results obtained. This process allows verifying that the software meets established requirements and that each component functions as expected. During test implementation, developers create a set of automated tests that run every time a change is made to the code, helping to identify errors early and ensuring the quality of the final product. Test implementation is not limited to verifying functionalities but also encompasses performance, security, and usability testing, among others. This proactive approach to fault detection helps reduce development costs and time, as it allows addressing issues before they become critical failures. Additionally, test implementation fosters a more disciplined and collaborative development culture, where teams work together to ensure that the software not only works but is also robust and reliable. In summary, test implementation is an essential component of the software development lifecycle, ensuring that products are of high quality and meet user expectations.
