Description: Systematic testing is a structured approach to testing that follows a defined process. This method is based on the idea that testing should be planned and executed methodically, ensuring that every aspect of the system is thoroughly evaluated. Systematic testing allows for more effective identification of errors and defects in software, as it focuses on requirement coverage and validation of expected behaviors. This approach is characterized by its emphasis on documentation, repeatability, and traceability, which facilitates communication among team members and improves the quality of the final product. Additionally, systematic testing is fundamental in software development methodologies, where the goal is to align software development with end-user expectations, ensuring that the product meets established acceptance criteria. In summary, systematic testing is an essential tool in the software development lifecycle, contributing to the creation of more robust and reliable applications.
