test_save_updates_numa_topology has a rather complex nova object to represent numa. This includes items which are sets, but must be converted to lists for json. This is not a stable output operation across all space and time. The mock comparator was failing here some times because of it. Instead, we can manually inspect the parameter in question with our json comparator to ensure that it is correct. Closes-Bug: #1473949 Change-Id: Ibfa441356d10417e2b1e092826562ad03d8cfd02
