Sure.
* Description is a string returned by the CI. In the test proposal given by
Thomas Monjalon, this could be the contents of the email sent by the CI system.
* Context is a non-unique name used to distinguish different tests (in the
broader sense). Examples would include: intel/license-check, intel/unit-tests,
dpdkorg/unit-tests/module1, dpdkorg/unit-tests/module2.
Is that clearer? I'm sorry but there is a limit of how much information I can
include in the models before messing up the 'admin' display. I plan to add
developer documentation in a follow up patch.

Ah - I think you are misunderstanding what a "Status" represents here. A status
does not represent the status of test that *has* to be run. It is a way of
reporting the status of *any* tests that *have* run. Patchwork doesn't care
what tests, if any, have been run: it is only an aggregator for results. This
makes sense as patchwork is not the place to be storing configuration for or
enforcing the tests that have to be run: all this management should be done
using existing tools and mailing lists. This also allows smarts on the CI
system whereby different tests can be run for different types of patches (a
change to files in the 'docs' folder would run different tests than a change to
'src'). In summary, it is not necessary to define a distinction between tests
and test results because we only care about the latter. Comprende? :)

You're right. What you'd actually need to do is test the last patch and set the
status on all patches. This might seem wasteful, but as far as you're concerned
it's true (we have assumed that those patches work, so we must mark them as
such). This has the benefit of allowing you to only test the last patch (and in
theory, the series) for some time-consuming tests (i.e. integration tests) but
keep doing per patch tests for other tests (i.e. license checks and unit
tests). This "special case" won't exist in patchwork itself, only the client
end (i.e. a custom script using the API. We won't be providing a client as it's
too implementation specific).
As far as series support goes, I'll leave that element of implementation to you
but I'd suggest looping through each SeriesPatch.status and accumulating the
results for each context. If any patch if missing a context found in one or
more other patches, you can set the series state to 'in progress'. Otherwise,
use the LCD approach. How's that sound?
