As explained in
https://fedoraproject.org/wiki/Changes/RemovePythonMockUsage,
python-mock is now deprecated. We ought to use mock from the python
standard library instead.
Maxwell G submitted a patch to libabigail's Fedora package in Rawhide
at 405c5046d8.
I am applying this patch inspired from his work here.
* configure.ac: Do not require python-mock anymore.
* tests/mockfedabipkgdiff.in: Use unittest.mock, not mock from
python-mock.

'''A local-only version of the fedabipkgdiff program
|
|
|
|
This program behaves exactly like the fedabipkgdiff tool, except
|
|
that it doesn't use the network (via the Koji client) to get Fedora
|
|
packages. The Koji client is the interface that is used to access
|
|
the Fedora build system to get Fedora binary packages.
|
|
|
|
This program thus loads the fedabipkgdiff tool and overloads
|
|
(replaces) its Koji Client session with a fake (also known as a
|
|
mock) Koji client named MockClientSession that gets the packages
|
|
locally. Packages are stored under the directory
|
|
tests/data/test-fedabipkgdiff/packages. This program then invokes
|
|
the fedabipkgdiff program just as if the user invoked it from the
|
|
command line.
|
|
|
|
This program is useful for tests that can be called from "make
|
|
check" because those must be able to perform in environments where
|
|
no network is avaible.
|
|
|
|
Please note that the descriptions of the builds of each package are
|
|
stored in at least three global variables below: packages, builds
|
|
and rpms.
|
|
|
|
Whenever a user wants to add a new build to the local set of builds
|
|
locally available via MockClientSession, she must update these three
|
|
variables.
