类 AbstractJUnit4SpringContextTests

@TestExecutionListeners({ServletTestExecutionListener.class,DirtiesContextBeforeModesTestExecutionListener.class,DependencyInjectionTestExecutionListener.class,DirtiesContextTestExecutionListener.class})
public abstract class AbstractJUnit4SpringContextTests
extends Object
implements ApplicationContextAware

Abstract base test class which integrates the Spring TestContext Framework with explicit ApplicationContext testing support in a JUnit environment.

Concrete subclasses should typically declare a class-level @ContextConfiguration annotation to configure the application contextresource locations or annotated classes. If your test does not need to load an application context, you may choose to omit the @ContextConfiguration declaration and to configure the appropriate TestExecutionListeners manually.

The following TestExecutionListeners are configured by default:

• ServletTestExecutionListener
• DirtiesContextBeforeModesTestExecutionListener
• DependencyInjectionTestExecutionListener
• DirtiesContextTestExecutionListener

This class serves only as a convenience for extension.

• If you do not wish for your test classes to be tied to a Spring-specific class hierarchy, you may configure your own custom test classes by using SpringRunner, @ContextConfiguration, @TestExecutionListeners, etc.
• If you wish to extend this class and use a runner other than the SpringRunner, as of Spring Framework 4.2 you can use SpringClassRule and SpringMethodRule and specify your runner of choice via @RunWith(...).

NOTE: As of Spring Framework 4.3, this class requires JUnit 4.12 or higher.
