Class Overview
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:
- 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
populateProtectedVariablesproperty totruein the constructor to switch on Field Injection.

Constants
public static final int AUTOWIRE_BY_NAME
Constant that indicates autowiring bean properties by name.

public static final int AUTOWIRE_BY_TYPE
Constant that indicates autowiring bean properties by type.

public static final int AUTOWIRE_NO
Constant that indicates no autowiring at all.

Public Constructors
public AbstractDependencyInjectionSpringContextTests ()
Default constructor for AbstractDependencyInjectionSpringContextTests.
public AbstractDependencyInjectionSpringContextTests (String name)
Constructor for AbstractDependencyInjectionSpringContextTests with a JUnit name.
Parameters
| name | the name of this text fixture |
|---|
Public Methods
public final int getAutowireMode ()
Return the autowire mode for test properties set by Dependency Injection.
public final boolean isDependencyCheck ()
Return whether or not dependency checking should be performed for test properties set by Dependency Injection.
public final boolean isPopulateProtectedVariables ()
Return whether to populate protected variables of this test case.
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.
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.
public final void setPopulateProtectedVariables (boolean populateFields)
Set whether to populate protected variables of this test case. Default is
false.
Protected Methods
protected void injectDependencies ()
Inject dependencies into 'this' instance (that is, this test instance).
The default implementation populates protected variables if the #populateProtectedVariables() 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 |
See Also
- #populateProtectedVariables()
protected void prepareTestInstance ()
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.
Throws
| Exception |
