Annotations

The Across Test library also provides a set of Across-specific annotations that extend the default Spring Testing annotations (eg @ContextConfiguration) to support AcrossContext setups.

@AcrossTestConfiguration

Class-level annotation to be used as an alternative to @EnableAcrossContext. Like @EnableAcrossContext this annotation will configure and bootstrap an AcrossContext but also add support for:

test datasources
easily exposing additional types for the scope of the test
resetting the database before bootstrap
creating a MockMvc bean instantiated with all dynamically registered filters from the context, when used in a @AcrossWebAppConfiguration test class

When using either @EnableAcrossContext or @AcrossTestConfiguration, all beans exposed can be wired directly in the unit test class.

Example using @AcrossTestConfiguration

@RunWith(SpringJUnit4ClassRunner.class)
@DirtiesContext
@ContextConfiguration
public class TestSample
{
	@Autowired
	private MyExposedBean myExposedBean;

	@Test
	public void doSomethingWithMyExposedBean() {
		...
	}

	@AcrossTestConfiguration(modules = MyModule.NAME, expose = MyExposedBean.class)
	protected static class Config
	{
	}
}

@AcrossWebAppConfiguration

Class-level annotation that sets up a @WebAppConfiguration test that uses a MockAcrossServletContext for initialization. @AcrossWebAppConfiguration contains a @ContextConfiguration annotation, unless additional annotations are specified, it will load static innter @Configuration classes of the annotated test class.

When using this annotation on a test class the MockAcrossServletContext instance can be autowired for introspection. In combination with an inner static @AcrossTestConfiguration class, this will support a MockMvc instance initialized with all dynamically registered filters.

Example combining @AcrossWebAppConfiguration and @AcrossTestConfiguration

@RunWith(SpringJUnit4ClassRunner.class)
@DirtiesContext
@AcrossWebAppConfiguration
@TestPropertySource( properties = "acrossWebModule.resources.versioning.enabled=false" )
public class TestSample
{
    @Autowired
    private MockAcrossServletContext servletContext;

	@Autowired
	private MockMvc mvc;

	@Test
	public void resourceUrlEncodingFilterShouldNotBeRegistered() {
        assertNull( servletContext.getFilterRegistration( ResourceUrlEncodingFilterConfiguration.FILTER_NAME ) );
	}

	@Test
	public void staticResourceShouldBeReturned() {
	    mvc.perform( get( "/across/resources/static/testResources/test.txt" ) )
           .andExpect( status().isOk() )
	}

	@AcrossTestConfiguration(modules = { AcrossWebModule.NAME })
	protected static class Config
	{
	}
}
