Class TestFactory

java.lang.Object
com.clarkware.junitperf.TestFactory
All Implemented Interfaces:
junit.framework.Test
Direct Known Subclasses:
TestMethodFactory
public class TestFactory extends Object implements junit.framework.Test
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.
