public abstract class AbstractDependencyInjectionSpringContextTests
extends AbstractSingleSpringContextTests

Convenient superclass for 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:

• Via Setter Dependency Injection. Simply express dependencies on objects in the test fixture, and they will be satisfied by autowiring by type.
• Via Field Injection. Declare protected variables of the required type which match named beans in the context. This is autowire by name, rather than type. This approach is based on an approach originated by Ara Abrahmian. Setter Dependency Injection is the default: set the "populateProtectedVariables" property to true in the constructor to switch on Field Injection.

1.1.1

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.

Overrides:

prepareTestInstance in class AbstractSingleSpringContextTests

Throws:

Exception
