Function TestJSONEncodeEntry

zapcore/json_encoder_test.go:39–151

TestJSONEncodeEntry is an more "integrated" test that makes it easier to get coverage on the json encoder (e.g. putJSONEncoder, let alone EncodeEntry itself) than the tests in json_encoder_impl_test.go; it needs to be in the zapcore_test package, so that it can import the toplevel zap package for fi

(t *testing.T)

// zapcore_test package, so that it can import the toplevel zap package for
// field constructor convenience.
