SYSTEM AND METHOD FOR SAFETY-CRITICAL SOFTWARE AUTOMATED REQUIREMENTS-BASED TEST CASE GENERATION

Automated requirements-based test case generation method 200 includes constructing 205 a software architecture model derived from software design model architectural information, allocating 210 requirement models into blocks/operators of the software architecture model, and generating 215 component-level requirements-based test cases from the software architecture configured to be executable at different levels in the software architecture. The component-level requirements-based test case generation method includes receiving a software architecture along with allocated requirement models represented in hierarchical data flow diagram, selecting one of the software components, building an intermediate test model based on the selected component by automatically attaching at least one of test objectives or constraints to the corresponding software architecture model blocks/operators based on the selected test strategy, and generating human and machine readable test cases with the test generator for further automatic conversion to test executable and test review artifacts. A system and a non-transitory computer-readable medium for implementing the method are also disclosed.
