public abstract class AbstractDependencyInjectionSpringContextTests
extends AbstractSingleSpringContextTests

Convenient superclass for JUnit 3.8 based tests depending on a Spring context. The test instance itself is populated by Dependency Injection.

Really for integration testing, not unit testing. You should not normally use the Spring container for unit tests: simply populate your POJOs in plain JUnit tests!

This supports two modes of populating the test:

See Also:
setAutowireMode(int), Constant Field Values

Constructor Detail

AbstractDependencyInjectionSpringContextTests

public AbstractDependencyInjectionSpringContextTests()
Default constructor for AbstractDependencyInjectionSpringContextTests.


AbstractDependencyInjectionSpringContextTests

public AbstractDependencyInjectionSpringContextTests(String name)
Constructor for AbstractDependencyInjectionSpringContextTests with a JUnit name.

Parameters:
name - the name of this text fixture
Method Detail

setPopulateProtectedVariables

public final void setPopulateProtectedVariables(boolean populateFields)
Set whether to populate protected variables of this test case. Default is false.


isPopulateProtectedVariables

public final boolean isPopulateProtectedVariables()
Return whether to populate protected variables of this test case.


setAutowireMode

public final void setAutowireMode(int autowireMode)

Set the autowire mode for test properties set by Dependency Injection.

The default is AUTOWIRE_BY_TYPE. Can be set to AUTOWIRE_BY_NAME or AUTOWIRE_NO instead.

See Also:
AUTOWIRE_BY_TYPE, AUTOWIRE_BY_NAME, AUTOWIRE_NO

getAutowireMode

public final int getAutowireMode()
Return the autowire mode for test properties set by Dependency Injection.


setDependencyCheck

public final void setDependencyCheck(boolean dependencyCheck)

Set whether or not dependency checking should be performed for test properties set by Dependency Injection.

The default is true, meaning that tests cannot be run unless all properties are populated.


isDependencyCheck

public final boolean isDependencyCheck()
Return whether or not dependency checking should be performed for test properties set by Dependency Injection.


prepareTestInstance

protected void prepareTestInstance()
                            throws Exception

Prepare this test instance, injecting dependencies into its protected fields and its bean properties.

Note: if the ApplicationContext for this test instance has not been configured (e.g., is null), dependency injection will naturally not be performed, but an informational message will be written to the log.

Overrides:
prepareTestInstance in class AbstractSingleSpringContextTests
Throws:
Exception - in case of preparation failure
See Also:
injectDependencies()

injectDependencies

protected void injectDependencies()
                           throws Exception

Inject dependencies into 'this' instance (that is, this test instance).

The default implementation populates protected variables if the appropriate flag is set, else uses autowiring if autowiring is switched on (which it is by default).

Override this method if you need full control over how dependencies are injected into the test instance.

Throws:
Exception - in case of dependency injection failure.
IllegalStateException - if the ApplicationContext for this test instance has not been configured.

populateProtectedVariables()
