`@ContextHierarchy`

@ContextHierarchy is an annotation that can be applied to a test class to define a hierarchy of ApplicationContext instances for integration tests. @ContextHierarchy should be declared with a list of one or more @ContextConfiguration instances, each of which defines a level in the context hierarchy. The following examples demonstrate the use of @ContextHierarchy within a single test class (@ContextHierarchy can also be used within a test class hierarchy):

Java
Kotlin

@ContextHierarchy({
	@ContextConfiguration("/parent-config.xml"),
	@ContextConfiguration("/child-config.xml")
})
class ContextHierarchyTests {
	// class body...
}

@ContextHierarchy(
	ContextConfiguration("/parent-config.xml"),
	ContextConfiguration("/child-config.xml"))
class ContextHierarchyTests {
	// class body...
}

Java
Kotlin

@WebAppConfiguration
@ContextHierarchy({
	@ContextConfiguration(classes = AppConfig.class),
	@ContextConfiguration(classes = WebConfig.class)
})
class WebIntegrationTests {
	// class body...
}

@WebAppConfiguration
@ContextHierarchy(
		ContextConfiguration(classes = [AppConfig::class]),
		ContextConfiguration(classes = [WebConfig::class]))
class WebIntegrationTests {
	// class body...
}

If you need to merge or override the configuration for a given level of the context hierarchy within a test class hierarchy, you must explicitly name that level by supplying the same value to the name attribute in @ContextConfiguration at each corresponding level in the class hierarchy. See Context Hierarchies and the @ContextHierarchy javadoc for further examples.
