JMock HasProperty Expectations

Took me a while to define JMock expectations which verifies that a argument of mocked method has a defined set of properties with values.

Here my JMock based JUnit test:

	import static org.fest.assertions.Assertions.*;
	import static org.hamcrest.Matchers.*;
	import org.hamcrest.Matcher;
	import org.jmock.Expectations;
	import org.jmock.Mockery;
	import org.jmock.integration.junit4.JUnit4Mockery;
	import org.jmock.lib.legacy.ClassImposteriser;
	import org.junit.After;
	import org.junit.Before;
	import org.junit.Test;
	public class TrackServiceTest
	{
	Mockery mockery = new JUnit4Mockery() {{
	setImposteriser(ClassImposteriser.INSTANCE);
	}};
	TrackService mockTrackService;
	@Before
	public void setup()
	{
	mockTrackService = mockery.mock(TrackService.class);
	}
	@After
	public void tearDown()
	{
	mockery.assertIsSatisfied();
	}
	@Test
	public void testPersitTrack()
	{
	final String jamesBlond = "James Blond";
	final String allTheLostSouls = "All the Lost Souls";
	// Setup Mock Object Track Service
	mockery.checking(new MyExpectations() {{
	oneOf(mockTrackService).persitTrack(
	with(
	any(Track.class),
	andAllOf(
	hasProperty("interpret", is(jamesBlond)),
	hasProperty("album", is(allTheLostSouls)))
	));
	will(returnValue(null));
	}});
	// Execute SUT
	Track track = mockTrackService.persitTrack(
	TrackBuilder.track()
	.withInterpret(jamesBlond)
	.withAlbum(allTheLostSouls)
	.build());
	// Verify
	assertThat(track).isNull();
	}
	class MyExpectations extends Expectations {
	public <T> T with(Matcher<T> valueMatcher, Matcher<Object> matcher)
	{
	return (T) with(matcher);
	}
	public Matcher<Object> andAllOf(Matcher<Object> ... matchers)
	{
	return allOf(matchers);
	}
	}
	}

Is there no better way to do this in JMock?
