@FunctionalInterface public interface ContextCustomizer
application contexts that are created and managed by the Spring
 TestContext Framework.
 Customizers are created by ContextCustomizerFactory implementations.
 
Implementations must implement correct equals and hashCode
 methods since customizers form part of the MergedContextConfiguration
 which is used as a cache key.
