/**
 * A jUnit runner to make your test classes and code behave like it would when run live in a di context ala Mockwire.
 *
 * The default context used for Dependency Injection is a manifest defined by the test class itself. It will only contain
 * {@link UnderTest code under test} and {@link Controlled controlled} classes in the actual test class or its super types.
 *
 *  * package net.stickycode.example;
 *
 * @RunWith(MockwireRunner.class)
 * public class ContainedTest {
 *
 *   @UnderTest
 *   SomeConcreteClass field;
 *
 *   @Inject
 *   SomeConcreteClass injectedInstanceOfBlessesClass;
 *
 *   @Inject
 *   IsolateTestContext context;
 *
 *   @Test
 *   public void testManifestHasCodeUnderTest() {
 *     assertThat(context.hasRegisteredType(ConcreteClass.class)).isTrue();
