public class DelayedInjectionRunner
extends org.junit.runners.BlockJUnit4ClassRunner

Custom JUnit runner which adds support for InjectDelayed and BeforeInjecting. This runner also initializes fields with Mockito's Mock, Spy and InjectMocks.

Mockito's Mock and InjectMocks are initialized before Before methods are run. This leaves no possibility to initialize some mock behavior before InjectMocks fields get instantiated.

The runner fills this gap by introducing BeforeInjecting. At the time these methods are run Mockito's annotation will have taken effect but not InjectDelayed. Fields with this annotation are initialized after BeforeInjecting methods have been run.

Additionally, after a field annotated with InjectDelayed has been initialized, its PostConstruct method will be invoked, if available.

Important: It is required to declare all dependencies of classes annotated with InjectDelayed as Mock fields. If a dependency is missing, an exception will be thrown.

run

public void run(org.junit.runner.notification.RunNotifier notifier)

createDelayedInjectsStatement

protected org.junit.runners.model.Statement createDelayedInjectsStatement(Object target,
                                                                          org.junit.runners.model.Statement statement,

Creates a statement that will instantiate the fields annotated with InjectDelayed. Override this method to provide another statement. For example, you can override RunDelayedInjects.getInjector() to use a differently configured injector.

Parameters:

target - the object the test will be run on

statement - the next statement

delayedFields - fields annotated with InjectDelayed

Returns:

the generated statement
