Annotation scopes

An annotation can have three scopes: global, class, method

Scope definitions

• Global scope
  The annotation applies on each QuickPerf test.
  To configure global scope annotations, create a class implementing SpecifiableGlobalAnnotations interface in an org.quickperf package.
  CoreAnnotationBuilder, SqlAnnotationBuilder, and JvmAnnotationBuilderare available to help to build global scope annotations.
• Class scope
  The annotation is on the test class. It overrides the configuration of the same annotation with global scope.
• Test method scope
  The annotation is on the test method. It overrides the configuration of the same annotation with test class and global scopes.
