<p class="MsoNormal"><span style="font-size:11.0pt;font-family:Calibri">The motivation in building the mocks this way was that we could easily generate a series of events which are different from one another. There used to be a distinction between ‘static fields’
and ‘dynamic fileds’, and a library named exrex was used to generate random values by regex definitions (e.g. "instance-[0-9]{7}"). We were then contacted by the infra team that exrex was not a known library in OpenStack (did not appear in global-requirements),
and we decided to remove it. You can still see in the code leftovers from the old implementation.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:Calibri"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:Calibri">I’m not sure if all datasources need the ability to generate a series of events. But since this is the way it was built, I decided to keep the structure in the Doctor datasourcde that I’ve
recently written. <o:p></o:p></span></p>

<p class="MsoNormal" style="margin-left:36.0pt">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?<o:p></o:p></p>
