Full platform tests - Exact match

[metalwarrior665]

Implement tests (or update current ones) that test few output fields on some specific value for an exact value. Try to pick only values you don't expect that will change. These tests can sometimes catch things that can slip through the schema check like when title starts capturing the description instead.
