I followed the same testing approach when writing a Wasm binary parser (technically, a decoder)[0].
It was pretty helpful having the official spec suite available and a major boost of confidence that your parser is compliant.
Nevertheless, it was my own tests that found a regression in the latest published version of the spec[1], which shows how important it is to have a variety of implementations.
