Test Suite Prioritization

From dis-Emi-A

by Classification

by Cause-Effect Level

Across an entire test-suite it makes sense to test to the same-depth on all test-cases before moving on the next depth of any individual test case. This ensures a broad coverage of the software with a good balance between valid and invalid situations.

If you are guaranteed to have enough time to go to a specific level, then you might wish to test directly to that level on the first path. For instance, in most situations if you've followed the recommend tree form, you'll have time to test to level 3 (as anything less would not produce a strong confidence in the test results).
