Automated Specification Extraction and Testing of Autonomous Systems

This exhibition presents two projects. The first project is a framework and associated tooling for the extraction of system specifications from test data that has been automatically generated from automated executions of the system. The test data in our framework consists of sequences of inputs to and the corresponding outputs from the system. From an initial collection of test data, data-mining techniques are used to infer the invariants; then the system is instrumented with the invariants and new test data is generated to try to invalidate the mined invariants.
