Which two tests are examples of tests beyond basic A/B tests?

• A. Redirect tests and multivariate tests
• B. Feature tests and pixel tests
• C. Regression tests and boundary tests
• D. Split tests and control tests

Answer: (A)

Beyond basic A/B testing, you want approaches that compare more than two options at once or that reveal how different parts of a page work together. Redirect tests fit this by evaluating entirely different URLs or experiences, not just changes on the same page. This lets you see how a complete path or funnel performs when users see a different destination, layout, or flow from what they’d normally experience. Multivariate tests take this a step further by testing many elements on a page at the same time to uncover how their different combinations affect outcomes. They’re not just asking which single element is better, but how multiple elements interact to influence behavior.

Other options don’t align with this idea. Feature tests and pixel tests focus more on deploying new capabilities or validating tracking signals rather than comparing distinct page experiences or interactions. Regression tests and boundary tests come from software quality assurance and are about ensuring code changes don’t break functionality or handle edge cases, not optimizing user experience through experiment variants. Split tests and control tests are terms that often overlap with A/B concepts, which are still considered basic testing approaches.
