<br>
Today at UCSC, Nathan, Chris (Moody) and I sat down and went through<br>
what we wanted to accomplish with testing. This comes back to the<br>
age-old dichotomy between unit testing and answer testing. But what<br>
this really comes back to, now that we had the opportunity to think<br>
about it, is the difference between testing components and<br>
functionality versus testing frontends.<br>
<br>
So the idea here is:<br>
<br>
Unit tests => Cover, using either manually inserted data values or<br>
randomly generated "parameter files", individual units of the code.<br>
Stephen and I have written a bunch in the last couple days. We have<br>
nearly 500, and they take < 1 minute to run.<br>
<br>
Frontend/Answer tests => Cover a large portion of high-level<br>
functionality that touches a lot of the code, but do so by running<br>
things like projections, profiles, etc on actual data from actual<br>
simulation codes, which then get compared to reference values that are<br>
stored somewhere. Currently we have ~550 answer tests, and they run<br>
every 30 minutes on moving7_0010 (comes wit yt) and once a day on<br>
JHK-DD0030 (on <a href="http://yt-project.org/data/" target="_blank">yt-project.org/data/</a> as IsolatedGalaxy .) We do not<br>
have automated FLASH testing.<br>
<br>
The next step is:<br>
<br>
1) Getting a bunch of non-proprietary sets of data that are small<br>
*and* medium, for each code base we want to test. This data must be<br>
non-proprietary! For small, I would say they can be trivially small.<br>
For medium, I'd prefer in the 0.5 - 5 gb range for size-on-disk. I<br>
would think that GasSloshing and WindTunnel could work for FLASH. But<br>
we still need ART data (from Chris Moody), GDF or Piernik data (from<br>
Kacper), Orion data (if possible), Nyx data (if possible). I will<br>
handle adding RAMSES data in the 3.0 branch.<br>
2) Getting a mechanism to run answer tests that isn't "Matt's<br>
desktop." I've emailed Shining Panda about this, but if they don't<br>
have the ability to provide us with a FLOSS license, I think we can<br>
identify some funding to do this.<br>
3) Have a mechanism to display and collate results. ShiningPanda<br>
would do this if we were on their systems.<br>
4) Make it much easier to flag individual tests as needing updates. I<br>
think the Data Hub will be the end place for this, but this is lower<br>
priority.<br>
5) Migrate answer testing to use unit testing framework, as most of<br>
what we've done there re-implements stuff that is in the unit testing<br>
frameworks. This will mean we can much more easily handle<br>
test-discovery, which is a huge plus.<br>
<br>
Ultimately, the end product of all of this is that we should<br>
eventually have a method for running a single set of tests that do<br>
test discovery that loads up a bunch of different data outputs, runs<br>
answer tests on all of them, runs the unit tests, etc etc. I think it<br>
just needs the last 25% to finish up the infrastructure.<br>
<br>
So: those of you out there who have access to any datasets of types<br>
otehr than FLASH or Enzo, can you provide non-proprietary, medium-size<br>
and small-size datasets? I'd like to have two for every code base, at<br>
least.<br>
<br>
So: those of you who want to help out, would you be interested in<br>
looking at the answer_testing framework with me? I am happy to<br>
discuss it over email or IRC to convert it to the numpy testing<br>
format, which will be much easier to maintain in the long run and make<br>
it much easier to have a single testing system that works for<br>
everything.<br>
