• testdata contains snapshot/golden test inputs and expectations for SDL parsing
• query_testdata and schema_data were later added, but for executable documents and SDL respectively. Theses cases were copied from the apollo-rs project at 721e0753 and the license at lang-graphql/tests/LICENSE-MIT applies to these. Cases added subsequently are licensed under this project's top-level license.
• some cases from the apollo lexer tests are copied with a 9xxx prefix
• schema_data cases are currently unused (TODO if SDL parsing is important)

A few full parse() cases were also added from graphql-js tests although they were not numerous or very interesting. They are added starting at ok/1111_*

Some ok cases that are only valid for the 2021 spec were renamed to *.2021 and ignored.

TODO

• the ok case output mostly has not been audited
• We might port the old testdata cases to the framework taken from apollo since it is nicer.
