tests: detect and warn missing spec_tests submodule #91

Closed LPardue closed 2 years ago

On a fresh checkout I forgot to clone recursively and the tests failed because I hadn't fetched the submodule containing the json test files. The test failure message is bit cryptic, so instead lets just panic with a more useful message that the user can action.

This is really helpful! Thank you!
