First, you need the dependencies. TestNG requires you to have a classifier for the jdk.

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

Now the testng.xml that is located in your test resources dir.

<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="domain" verbose="5">

	<test name="DomainObjectFactoryTests">
		<packages>
			<package name="com.stephennimmo.domain.test" />
		</packages>
	</test>

</suite>

Here's the test class. Pay attention that it extends the AbstractTestNGSpringContextTests. If you want transactions involved, extend AbstractTransactionalTestNGSpringContextTests and set it up in the @BeforeClass.

@ContextConfiguration(locations={"classpath:ServiceFactoryContext.xml"})
public class TestPersonService extends AbstractTestNGSpringContextTests {

	@Autowired
	private PersonService personService;

	@Test(groups = { "service" })
	public void testPersonService(){
		long id = 1000;
		Person p = personService.find(id);
		assertNotNull(p);
		assertEquals(p.getId(), id);
	}

}
