The Classification Tree Editor (CTE) is integrated with TESSY. The CTE supports the Classification Tree Method (CTM). This method transforms a problem specification into a set of error-sensitive, low-redundancy test case specifications. The method incorporates equivalence partitioning and boundary value analysis. The objective of the Classification Tree Method is to determine a sufficient but minimum number of test case specifications.
The Classification Tree Method addresses questions like
- How many tests should be run?
- What test data should be used?
- How can redundant test cases be avoided?
- Have any test cases been overlooked?
- When is it safe to end testing?
