System test and validation with automated search for critical scenarios
TestWeaver is a tool for automated validation of simulated systems. TestWeaver generates, runs and evaluates thousands of test scenarios automatically. Each test scenario is a sequence of inputs over time, automatically performed using simulation. TestWeaver generates the tests in a reactive, informed way, trying learn the system behavior from the results of the past simulations, in order to increase state coverage and to actively worsen sub-optimal scenarios until the system behavior is really bad, i.e. a bug or a design flaw has been found. TestWeaver supports as well classical test automation methods, based on:
- interactive recording and replay of scenarios
- user-defined test scripts, for instance with Python.
- Fast development: early problem detection
- High test coverage: thousands of high-quality tests
- Low work load: more automation, less scripting
TestWeaver is in use for automated test and validation at AMG, Bosch, Mercedes-Benz, Porsche, Volvo Car Corporation, IAV, SAIC, TREMEC, ZF and others.
