Testing / Ranorex Interview questions
Why should you use user code collections in Ranorex?
A user code collection is a shared C#/VB.NET class added to the project that any module can call into, and it exists to stop the same logic from being copy-pasted across multiple test cases.
Common candidates are a login helper used at the start of many test cases, a custom retry-with-backoff routine, or a validation helper that checks a business rule more specific than a plain Validate.Attribute call - anything that more than one module needs and that should behave identically everywhere it's used.
The payoff shows up during maintenance: if the login flow changes, fixing the one method in the user code collection updates every test case that calls it, instead of hunting down and editing every place the old steps were duplicated. This is the same DRY (don't repeat yourself) reasoning that applies to any codebase, just applied to a Ranorex suite's helper logic.
