Test annotation which indicates that the annotated
should be executed before a transaction is started for a test method
configured to run within a transaction via Spring's
@BeforeTransaction methods declared in superclasses or as interface
default methods will be executed before those of the current test class.
As of Spring Framework 4.0, this annotation may be used as a
meta-annotation to create custom composed annotations.
As of Spring Framework 4.3,
@BeforeTransaction may also be
declared on Java 8 based interface default methods.
