Direct Known Subclasses:

public abstract class AbstractSpringContextTests
extends ConditionalTestCase

Superclass for JUnit test cases using Spring ApplicationContexts.

Maintains a static cache of contexts by key. This has significant performance benefit if initializing the context would take time. While initializing a Spring context itself is very quick, some beans in a context, such as a LocalSessionFactoryBean for working with Hibernate, may take some time to initialize. Hence it often makes sense to do that initializing once.

Any ApplicationContext created by this class will be asked to register a JVM shutdown hook for itself. Unless the context gets closed early, all context instances will be automatically closed on JVM shutdown. This allows for freeing external resources held by beans within the context, e.g. temporary files.

Normally you won't extend this class directly but rather extend one of its subclasses.

Since:

1.1.1

Constructor Detail

AbstractSpringContextTests

public AbstractSpringContextTests()

Default constructor for AbstractSpringContextTests.

---

AbstractSpringContextTests

public AbstractSpringContextTests(String name)

Constructor for AbstractSpringContextTests with a JUnit name.

Method Detail

addContext

public final void addContext(Object key,
                             ConfigurableApplicationContext context)

Explicitly add an ApplicationContext instance under a given key.

This is not meant to be used by subclasses. It is rather exposed for special test suite environments.

Parameters:

key - the context key

context - the ApplicationContext instance

---

hasCachedContext

protected final boolean hasCachedContext(Object contextKey)

Return whether there is a cached context for the given key.

Parameters:

contextKey - the context key

---

getContext

protected final ConfigurableApplicationContext getContext(Object key)
                                                   throws Exception

Obtain an ApplicationContext for the given key, potentially cached.

Parameters:

key - the context key

Returns:

the corresponding ApplicationContext instance (potentially cached)

Throws:

Exception

---

setDirty

protected final void setDirty(Object contextKey)

Mark the context with the given key as dirty. This will cause the cached context to be reloaded before the next test case is executed.

Call this method only if you change the state of a singleton bean, potentially affecting future tests.

---

contextKeyString

protected String contextKeyString(Object contextKey)

Subclasses can override this to return a String representation of their context key for use in logging.

Parameters:

contextKey - the context key

---

loadContext

protected abstract ConfigurableApplicationContext loadContext(Object key)
                                                       throws Exception

Load a new ApplicationContext for the given key.

To be implemented by subclasses.

Parameters:

key - the context key

Returns:

the corresponding ApplicationContext instance (new)

Throws:

Exception
