Test Case Equivalence Part 4

In the last post, I presented interesting implications of the model of a test case, such as the mathematical object that captures a test’s essence:  the core. In this post, I’ll explain how these concepts can help us reduce our testing workload by telling us whether a test does some of the things that another test […]


Test Case Equivalence Part 2

In this post, I continue exploring the vague concept of test case duplication. Eventually, my final goal is to precisely define what we mean in the testing industry by the phrase “duplicate tests.” For that, I’ll cover here a critical concept that will guide our understanding of when test case duplication happens and why it occurs.

How many of these sound familiar to you? “this test is already covered by that other one” “this test is a superset of that one” “these tests seem to cover the same thing” “these two tests are very similar” “this test covers related aspects/functionality as that other test” “these two tests are equivalent” I’ve heard […]
