More pretty comparisons / debugging for tests

[cdrage]

[kind/Feature]

Which functionality do you think we should add?

We should utilize: https://godoc.org/github.com/kylelemons/godebug/pretty#example-Compare--Debugging

in tests in order to "prettify" and make debugging A LOT easier when something fails.

I've been using this periodically when debugging and I believe we should implement this into the integration tests.

Why is this needed?

I'll take this up as it's pretty straight-forward to implement ^^
