Previously the only roundtrip test was for an empty report. This test has fake data similar to that found in real reports.
Node.Metrics
does not round-trip exactly: it is tagged withomitempty
so when decoded an empty map turns into the zero value. ADeepEqual
workaround is added so the test passes.Perhaps it would be better to adjust the decode so the field is not nil after decoding.
This PR is a precursor to tests which check backwards compatibility: for instance that the binary data encoded by version 1.2 still decodes to the expected structure.
