Description: Lifecycle Testing is a comprehensive approach that is implemented throughout all phases of software product development. This concept is based on the premise that software quality should not be a concern exclusive to the final development phase, but should be considered from the project’s inception. Testing is conducted at each stage, from planning and design to implementation and maintenance, ensuring that each component of the software meets established requirements and functions correctly. This approach allows for early identification and correction of errors, reducing costs and improving the efficiency of the development process. Additionally, it fosters a culture of quality within the development team, where all members are responsible for the quality of the final product. Lifecycle Testing is essential to ensure that the software not only meets customer expectations but is also robust, scalable, and easy to maintain over time.
