# The tests for the RPC module need to cover multiple possible combinations:
# - different aspects of the API, each one having its own suite of tests;
# - different agents (ProcessGroup, TensorPipe, ...);
# To avoid a combinatorial explosion in code size, and to prevent forgetting to
# add a combination, these are generated automatically by the code in this file.
# Here, we collect all the test suites that we need to cover.
# We then have one separate file for each agent, from which
# we call the generate_tests function of this file, passing to it a fixture for
# the agent, which then gets mixed-in with each test suite.
