[meta] Audit public test methods that return something and validate that it actually makes sense in each case

Problem/Motivation

In reviewing 📌 Add void return typehints to all test methods Active , we noticed there are any number of what appear to be public test methods that have return values.

Proposed resolution

• Review these methods and validate whether they actually need to return something (and document why).
• Where appropriate, if they are test helper methods, convert them to protected and then include them in the scope of 🌱 Add return typehints to protected test helper methods Active .
• If the method doesn't actually need to return anything, simply remove the return value and add the appropriate void return typehint.
