Since Editions are relatively new, only implementations that advertise support are tested with Editions.
Note: None of the libraries tested implement the text format, so the results for those test runs are not shown.
To run the conformance tests, run npm test from the repo root.
Note that only Linux and OSX operating systems are supported.
