This simplifies and enhances the functional-test runner script for
much better interactive behaviour and to give us the ability to better
choose what is running in CI.
Firstly, I have split the image-output testing into a separate script.
This is not actually part of the functional testing of elements and is
both logically and functionally different. It currently does not run
in upstream CI because we don't have docker in the images. I have
nothing against it, but it can be it's own thing.
run_functests.sh is overhauled to have a useful interactive interface,
e.g.
---
$ ./run_functests.sh -h
run_functests.sh [-h] [-l] <test> <test> ...
-h : show this help
-l : list available tests
<test> : functional test to run
Special test 'all' will run all tests
$ ./run_functests.sh -l
The available functional tests are:
apt-sources/test-sources
debian/build-succeeds
fedora/build-succeeds
fedora/build-succeeds-f21
ironic-agent/build-succeeds-fedora
---
As described there, you can run a single test, a number of tests, the
default tests (as CI will do) or all tests. Running all tests is too
much for regular CI, but currently the only way to stop a low priority
test running, or temporarily pause is to remove it completely --
clearly sub-optimal (see I93c2990472e88ab3e5ff14db56b4ff1b4dd965ef).
There is nothing complicated about this, and to further simplify I
have merged the runner functions back into run_functests.sh which
remains a very modest ~150 lines, with most of that being argument
sanity. With that and the image-format cleanup, we can remove the
indirection of the 3 small library files.
For consistency, I have renamed the "dib_functions_test" (that tests
things from the dib functions library) with a run_* prefix.
Because the default list is the same as the current functional tests
run, this does not modify the status-quo. I plan to modify this,
however, to run fedora-minimal & centos-minimal tests in a future
change, as these are required to be stable for openstack ci.
Documentation is updated, and a README.rst is added in the tests
directory for discoverability.
