Automated requirements-based testing on Boeing 777 display

On the 777 Airplane Program, Boeing required their suppliers to perform requirements-based testing on their embedded software systems. Honeywell defined an "Integrated Testing Philosophy" and developed a set of tools to automate the philosophy. Software through Pictures from Interactive Development Environments was being used for requirement analysis, but most of the test engineers ignored the requirement models and simply read the requirements documents to determine the test cases. During the evaluation of T, a test case generation from Programming Environments Inc. the Displays Organization recognized the potential to automatically generate test cases from information that had been captured in the Software through Pictures models by the analysts. The Displays fool integration project integrated Software through Pictures and T with Honeywell tools to provide a complete solution for requirements-base testing.
