Spring Parametrized Integration Test, SpringJUnit4ClassRunnerFactory usage example

StringParametrizedIntegrationTest.java

@Parameterized.UseParametersRunnerFactory(SpringJUnit4ClassRunnerFactory.class)
@RunWith(Parameterized.class)
@SpringTestConfiguration
@Transactional
public class StringParametrizedIntegrationTest {

    @Parameterized.Parameter
    public String uri;

    @Parameterized.Parameters(name = "{index}: for {0} ")
    public static Collection<Object[]> data() {
        return Arrays.asList(new Object[][]{
                {"test1"},
                {"test2"}
        });
    }


    @Autowired
    Helper helper;

    @Test
    public void test() throws Exception {
        assertThat(uri, helper.loadArray(uri), arrayWithSize(greaterThan(0)));
    }
}

class SpringJUnit4ClassRunnerFactory implements ParametersRunnerFactory {

    @Override
    public Runner createRunnerForTestWithParameters(final TestWithParameters test) throws InitializationError {
        final LocalBlockJUnit4ClassRunnerWithParameters testRunner = new LocalBlockJUnit4ClassRunnerWithParameters(test);

        return new SpringJUnit4ClassRunner(test.getTestClass().getJavaClass()) {
            @Override
            protected Object createTest() throws Exception {
                final Object testInstance = testRunner.createTest();
                getTestContextManager().prepareTestInstance(testInstance);
                return testInstance;
            }

            @Override
            protected String getName() {
                return testRunner.getRealName();
            }
        };
    }

    private class LocalBlockJUnit4ClassRunnerWithParameters extends BlockJUnit4ClassRunnerWithParameters {

        public LocalBlockJUnit4ClassRunnerWithParameters(final TestWithParameters test) throws InitializationError {
            super(test);
        }

        String getRealName() {
            return getName();
        }
    }
}

This is great!
