Quick diagnosis:
Tempest is a branchless and its master branch inherited post-liberty dependencies through updates of global-requirements. The requirements are not provided by the packages, but tempest CLI seems to work anyway even with Liberty dependencies.
Lowering the dependencies in openstack-tempest and python-tempest-lib to the releases available in the packages seems to fix it.  

Version-Release number of selected component (if applicable):
openstack-tempest-liberty-20160126.1.el7ost.noarch
python-tempest-lib-0.13.0-1.el7ost.noarch

Cloned for python-tempest-lib, as the dependencies need to be fixed on both packages.
