Kent Tong commented on HIVEMIND-186:
------------------------------------

I've implemented this feature. The code is in the patch for HIVEMIND-185. I implemented both at the same time. It's difficult to separate them now.

Here is an example using this feature:

public class TestRegistryBuilderUsingStrings extends TestCase
{
	...
	public void testOverrideImplementation() throws Exception
	{
		String module1 = "<?xml version=\"1.0\"?>"
				+ "<module id=\"com.myco.mypackage\" version=\"1.0.0\">"
				+ "  <service-point id=\"Adder\" interface=\"org.apache.hivemind.Adder\"/>"
				+ "</module>";
		String module2 = "<?xml version=\"1.0\"?>"
				+ "<module id=\"com.myco.mypackage.impl\" version=\"1.0.0\">"
				+ "  <implementation service-id=\"com.myco.mypackage.Adder\">"
				+ "  <create-instance class=\"org.apache.hivemind.AdderImpl\"/>"
				+ "  </implementation>" + "</module>";
		ServiceImplOverride override = new ServiceImplOverride(
				"com.myco.mypackage.Adder", new Adder()
				{
					public int add(int arg1, int arg2)
					{
						return 123;
					}
				});
		setupRegistry(new String[] { module1, module2 },
				new ServiceImplOverride[] { override });
		Adder adder = (Adder) registry.getService("com.myco.mypackage.Adder",
				Adder.class);
		assertNotNull(adder);
		assertEquals(adder.add(4, 5), 123);
	}
}

> This is useful when performing integration tests involving hivemind services. As one hivemind service can bring in another. To stop it we can use override a certain "boundary" service implementations using stub/mock objects. I need this capacity to test Tapestry pages (eg, provide a stub HttpServletRequest).
