Comparison Testing: Test Cases results are compared with the predicted results of the Test Oracle (Test Oracle: a mechanism to produce the predicted outcomes to compare with the actual outcomes of the software under test [from BS7925-1])

It's a bit of an old fashioned term, in that predicted results are usually included in the test case script. A test matrix with expected result values could be called a test oracle, or a predictive spreadsheet could fulfil that function.

Note: Software Testing has developed many redundant/overlapping terminologies over the last decade.

e.g. Black Box Testing aka Behavioural Testing aka Functional Testing

Don't get too hung up with the terminology, as it varies from organisation to organisation.
