Interface TestContextBootstrapper

All Known Implementing Classes:

AbstractTestContextBootstrapper, DefaultTestContextBootstrapper, WebTestContextBootstrapper

public interface TestContextBootstrapper

TestContextBootstrapper defines a strategy SPI for bootstrapping the Spring TestContext Framework.

A custom bootstrapping strategy can be configured for a test class via @BootstrapWith, either directly or as a meta-annotation. See @WebAppConfiguration for an example.

The TestContextManager uses a TestContextBootstrapper to get the TestExecutionListeners for the current test and to build the merged context configuration necessary to create the TestContext that it manages.

Concrete implementations must provide a public no-args constructor.

Note: this SPI might potentially change in the future in order to accommodate new requirements. Implementers are therefore strongly encouraged not to implement this interface directly but rather to extend AbstractTestContextBootstrapper or one of its concrete subclasses instead.

Method Summary

Modifier and Type	Method and Description
MergedContextConfiguration	buildMergedContextConfiguration() Build the merged context configuration for the test class in the BootstrapContext associated with this bootstrapper.
BootstrapContext	getBootstrapContext() Get the BootstrapContext associated with this bootstrapper.
List<TestExecutionListener>	getTestExecutionListeners() Get a list of newly instantiated TestExecutionListeners for the test class in the BootstrapContext associated with this bootstrapper.
void	setBootstrapContext(BootstrapContext bootstrapContext) Set the BootstrapContext to be used by this bootstrapper.

Method Detail

setBootstrapContext

void setBootstrapContext(BootstrapContext bootstrapContext)

Set the BootstrapContext to be used by this bootstrapper.

getBootstrapContext

BootstrapContext getBootstrapContext()

Get the BootstrapContext associated with this bootstrapper.

getTestExecutionListeners

List<TestExecutionListener> getTestExecutionListeners()

Get a list of newly instantiated TestExecutionListeners for the test class in the BootstrapContext associated with this bootstrapper.

If @TestExecutionListeners is not present on the test class in the BootstrapContext, default listeners should be returned. Furthermore, default listeners must be sorted using AnnotationAwareOrderComparator.

Concrete implementations are free to determine what comprises the set of default listeners. However, by default, the Spring TestContext Framework will use the SpringFactoriesLoader mechanism to look up all TestExecutionListener class names configured in all META-INF/spring.factories files on the classpath.

The inheritListeners flag of @TestExecutionListeners must be taken into consideration. Specifically, if the inheritListeners flag is set to true, listeners declared for a given test class must be appended to the end of the list of listeners declared in superclasses.

Returns:

a list of TestExecutionListener instances

buildMergedContextConfiguration

MergedContextConfiguration buildMergedContextConfiguration()

Build the merged context configuration for the test class in the BootstrapContext associated with this bootstrapper.

Implementations must take the following into account when building the merged configuration:

• Context hierarchies declared via @ContextHierarchy and @ContextConfiguration
• Active bean definition profiles declared via @ActiveProfiles
• Context initializers declared via ContextConfiguration.initializers()

Consult the Javadoc for the aforementioned annotations for details on the required semantics.

When determining which ContextLoader to use for a given test class, the following algorithm should be used:

1. If a ContextLoader class has been explicitly declared via ContextConfiguration.loader(), use it.
2. Otherwise, concrete implementations are free to determine which ContextLoader class to use as as default.

Returns:

the merged context configuration, never null
