All Implemented Interfaces:

Serializable

Direct Known Subclasses:

WebMergedContextConfiguration

public class MergedContextConfiguration
extends Object
implements Serializable

MergedContextConfiguration encapsulates the merged context configuration declared on a test class and all of its superclasses and enclosing classes via @ContextConfiguration, @ActiveProfiles, and @TestPropertySource.

Merged context resource locations, annotated classes, active profiles, property resource locations, and in-lined properties represent all declared values in the test class hierarchy and enclosing class hierarchy taking into consideration the semantics of the ContextConfiguration.inheritLocations(), ActiveProfiles.inheritProfiles(), TestPropertySource.inheritLocations(), and TestPropertySource.inheritProperties() flags.

A SmartContextLoader uses MergedContextConfiguration to load an ApplicationContext.

MergedContextConfiguration is also used by the ContextCache as the key for caching an ApplicationContext that was loaded using properties of this MergedContextConfiguration.
