The test of TestL3NatPlugin don't looks like testing l3 plugin. It tests how controller pass the params to plugin and how contoller return the result. So it similar with test_api_v2.py:JSONV2TestCase doing.
I suggest move all test of TestL3NatPlugin to L3NatDBTestCase, test with db. And remove TestL3NatPlugin
