The class only test serialization, is it incorrectly named or did you forget
about deserialization testing?

[qsr, 2014/09/15 11:01:53]

 Deserialization is not implemented in this CL. Test for it will be added here.
I want to test both at the same time, because the easier way to do a non trivial
test of the process is starting with an entity, serialize it/ deserialize the
result and check that the result has the same fields as the initial one.

[sdefresne, 2014/09/15 11:14:46]

Make sense.

[qsr, 2014/09/15 11:42:00]

Acknowledged.
