# Prerequisites:
# * set up any method stubs on the git repo to raise error, e.g.
#     before { allow(git_repo).to receive(:pull).and raise_error(error) }
# * define a method named retry_git_command to set up retry expectations, e.g.
#     let(:retry_git_command) do
#       expect(git_repo).to have_received(:pull).exactly(retry_limit).times
#     end
