Refactor some tests inside of builders_helper_test.go
Overview
We have a few ~"technical debt" inside of the builders_helper_test.go that we can get rid off fairly easily.
- Looking at the rest of the Runner codebase we usually use anonymous structs for test cases unless there is a need for reuse.
- Instead of using a custom struct
newFakeResponseWriter
we can use the built in ResponseRecorder provided by go stdlib.
