Creating a reference or field reference
When you designate a test
value as a reference or designate a set of test data as a field reference,
you can use the data elsewhere in the test.
About this task
A reference, which is typically located in response data, points to a specific value that you want to use in a subsequent test location, typically a request. You can substitute a request value with a reference. This substitution is called data correlation. You can also use a reference as input to an IF-THEN condition in a test or as input to custom Java™ code that your test calls.
A field reference points to an entire block of test data. For example, an entire HTTP response can be designated as a field reference. You can use a field reference as input to custom Java code that your test calls.
