/**
 * Superclass for JUnit 3.8 based tests that allows conditional test execution

 * method is invoked before the execution of each test method. Subclasses can
 * override that method to return whether or not the given test should be
 * executed. Note that the tests will still appear to have executed and passed;
 * however, log output will show that the test was not executed.
