Similar to junit, a test suite is defined as an empty Java classes with a org.aludratest.Suite annotation which lists the suite components. Each suite component may be a simple test class or a suite itself. Thus, suite structures can be nested arbitrarily deeply.
Example:
import org.aludratest.Suite;
@Suite({
MyTestClass1.class,
MyTestClass2.class,
NestedTestSuite.class
})
public class MyTestSuite {}
