Discussion: GraphQL Spec Compliance Tests

Hello maintainers
As a part of research around the simplifying graphql spec tests across implementations, I've stumbled upon the specs written here for `graphql-go`. I'd really appreciate if I can get an idea around how difficult it has been to maintain this test suite, and how often does it go out of parity with the actual graphql spec? Were there cases when misunderstanding the spec led to issues with the library?

#### Would having a generic set of compatibility tests help around these issues if any?

As schema definition in SDL format is natively supported by the library then it would be easy to adapt generic testing suite across different languages.
