# Examples:
#
# * Running all tests under fedjax/ (default):
#
#     ./run_tests.sh
#
# * Running tests in directory fedjax/core:
#
#     ./run_tests.sh fedjax/core
#
# * Running tests in fedjax/fedjax_test.py and directory fedjax/core:
#
#     ./run_tests.sh fedjax/fedjax_test.py fedjax/core

# TODO(wuke): Run tests in parallel. We need to deal with race conditions caused
# by multiple tests accessing temporary files with the same name (e.g.
# "test_sqlite_federated_data.sqlite" in both
# fedjax/core/sqlite_federated_data_test.py and
# fedjax/core/federated_data_test.py
