Hi, Root Causers In the implementation of static driver unit test, the most difficult part I've encountered is the mock driver and trace generator. Is there any particular reason to put all mock driver and transformer specs in the same file `trace_generator.py` and `mock_driver.py`? Would it be easier to maintain and extend if we organize the specs and drivers in datasource, e.g. `mock.static`, `mock.nova.host` and etc? -- Yujun -------------- next part -------------- An HTML attachment was scrubbed...
