Examples of nz.ac.waikato.modeljunit.Tester

nz.ac.waikato.modeljunit.Tester
An abstract superclass for all the test generation algorithms. Each subclass must implement a {@link #generate()} method thatgenerates the next step in a test sequence.
Note that many test generation algorithms use randomness, so this class provides a setter and getter for a random number generator. By default this is set to new Random(FIXEDSEED), so that test generation is deterministic. @author marku
