Class TestClassPool

java.lang.Object
  de.bechte.junit.runners.model.TestClassPool

public final class TestClassPool
extends Object

This pool of TestClasses is used to reduce the expensive look-ups and reflection calls that are performed during the construction of the TestClass instances. The pool will keep a reference to each instance so that no TestClass has to be constructed twice. Note: The additional memory consumption for keeping the instances is very low, but the pool results in a tremendous speed-up in case of the HierarchicalContextRunner, when TestClasses must be recreated several times along the context hierarchy.
