Introduce autowiring support for the current TestContext [SPR-8299]

[spring-projects-issues]

Sam Brannen opened SPR-8299 and commented

Status Quo

Tests currently do not have access to the current TestContext.

Providing access to the TestContext would allow programmatic access to TestContext properties as well as methods such as markApplicationContextDirty().

Considerations

Instead of exposing the TestContext as is, it may be preferential to expose a new (yet-to-be-implemented) public-facing interface that defines a subset of the publicly available methods in TestContext.

A similar approach could be introduced to provide programmatic support for transaction management.

Code Samples

DependencyInjectionTestExecutionListener's injectDependencies(TestContext) method could be modified as follows:

protected void injectDependencies(final TestContext testContext) throws Exception {
	Object bean = testContext.getTestInstance();
	ApplicationContext applicationContext = testContext.getApplicationContext();

	// BEGIN NEW CODE
	// Enable autowiring of the current TestContext.
	if (applicationContext instanceof ConfigurableApplicationContext) {
		ConfigurableApplicationContext configurableApplicationContext = (ConfigurableApplicationContext) applicationContext;
		configurableApplicationContext.getBeanFactory().registerResolvableDependency(TestContext.class, testContext);
	}
	// END NEW CODE

	AutowireCapableBeanFactory beanFactory = applicationContext.getAutowireCapableBeanFactory();
	beanFactory.autowireBeanProperties(bean, AutowireCapableBeanFactory.AUTOWIRE_NO, false);
	beanFactory.initializeBean(bean, testContext.getTestClass().getName());
	testContext.removeAttribute(REINJECT_DEPENDENCIES_ATTRIBUTE);
}

public class MyTests {

	@Autowired
	protected TestContext testContext;

	@Test
	public void test() {
		assertNotNull(testContext);
		assertEquals("test", testContext.getTestMethod().getName());
	}
}
