# The tests are sourcing the mocks file to mock out various functions. The
# mocking-out always happens in a sub-shell, thus it does not have impact on
# the functions defined here.
# To run the tests, please run:
#
# ./test_functions.sh run_tests

# To only print out the discovered test functions, run:
