It’s important to know the equivalence classes for your system under test, because you can use equivalence classes to limit your test cases. Let’s look at an example. Let’s say you have a user interface that looks like this: Remember, […]
Data driven testing solves the problem: “I want to try a bunch of different test values, but I don’t want to write a different test for each one.” In data driven testing, you reuse the same test code with different values. Data-driven testing is so common and valuable that I’ve seen teams set up their […]
“Regression testing is doing the same thing over and over and expecting a different result.” This is a series of articles on test automation techniques you can use for regression testing. The goals of the series are to: These techniques are not tied to any tool. However, I’ll use some examples in NUnit because it’s […]
