[ovirt-devel] ovirt-system-tests hackathon report

Tue Mar 13 17:14:32 UTC 2018

Hello there,

I indeed missed this event.
Nevertheless, I would like to add one remark:

The existing suites have differences in how they run the tests and how the
tests are written.
At the networking team, we found the original suites way of running things
and how tests are written problematic.
As a result, work has been done to make it more usable: control its run
flow, use advance capabilities from test frameworks (pytest) and make it as
simple as possible for a developer to add a test.
The result is seen in the network suite, which runs using pytest, has a lib
that wraps the SDK in a more "natural" manner, includes fixtures to handle
resources at different scopes and even has an ansible test.
Tests are NOT dependent on each other in any way, but they may require the
same resource (here fixtures play a role).

You are welcome to feedback on anything you see there, we are trying to
make it dead simple to write tests.

Thanks,
Edy.
