In what software testing technique does the evaluator retest a large number of scenarios each time that the software changes to verify that the results are consistent with a standard baseline?

Regression testing is performed after developers make changes to an application. It reruns a number of test cases and compares the results to baseline results. Orthogonal array testing is a method for generating test cases based on statistical analysis. Pattern testing uses records of past software bugs to inform the analysis. Matrix testing develops a matrix of all possible inputs and outputs to inform the test plan.
