Class TestFactory

java.lang.Object
  com.clarkware.junitperf.TestFactory

Direct Known Subclasses:

TestMethodFactory

public class TestFactory
extends java.lang.Object

The TestFactory class creates thread-local TestSuite instances.

This factory class should be used in cases when a stateful test is intended to be decorated by a LoadTest. A stateful test is defined as any test that defines test-specific state in its setUp() method.

Use of the TestFactory ensures that each thread spawned by a LoadTest contains its own TestSuite instance containing all tests defined in the specified TestCase class.

A typical usage scenario is as follows:

 Test factory = new TestFactory(YourTestCase.class);
 LoadTest test = new LoadTest(factory, numberOfUsers, ...);
 ...
 

Of course, static variables cannot be protected externally, so tests intended to be run in a multi-threaded environment should ensure that the use of static variables is thread-safe.

This class is dependent on Java 2. For earlier platforms a local cache implementation should be changed to use, for example, a HashMap to track thread-local information.
