value
String valueThe default value to pass to this parameter.The default deserves a bit of explanation. JSR-175 (which defines annotations) says that Java annotation parameters can only be ConstantExpressions, which can be primitive/string literals, but not
null
.In this case, we use this string as a substitute for
null
; in practice, TestNG will passnull
to your code, and not the string "null", if you do not specify a default value here in this parameter.- Returns:
- the value (default NULL_VALUE)
- Default:
- "null"
