This research aims to provide a practical work on the principle of the Extreme Programming (XP) which is a type of the Agile Software Development Methods which is used in the generation of test-cases using the design information.  The resources utilized in the design information presented here are the design diagrams generated using the Unified Modeling Language (UML), as they are considered to be the most commonly used modeling language in these days, and also the newest. These UML diagrams are used to automatically develop a set of high quality test cases which are then used to test the system’s code after being written. The main idea of this work is based on reducing the effort of the testing stage which costs more than 50% of the resources allocated for the whole development process; this cost may include the financial cost, the cost of the resources allocated for the project, and the timeline of the project. In this work, enhancements have been made to the concept of Gene Expression Programming to ensure the generation of high quality the test cases that are generated automatically, and a solution has been presented for the parallel paths and the loop paths problems that are found in the design.
