Test Case Generation from a Z Specification of the Landing Gear System
In this technical report we present the results of a case study on the application of a model-based testing method (MBT) to a real-world problem from the aviation industry. The requirements wereproposed by engineers working for the European aviation industry and comprise the landing gear system (LGS) of an aircraft. We developed a complete Z specification of the control software of the LGS. Then, we automatically generated abstract test cases by applying FASTEST (a tool implementing the Test Template Framework, which is a MBT method). These test cases cover all the functional and real-time scenarios described in the requirements. The manual work required to generate them is minimum.
