+Utilities for mocking the IBMQ provider, including job responses and backends.
+
+The module includes dummy provider, backends, and jobs.
+The purpose of these classes is to fake backends for testing purposes:
+testing local timeouts, arbitrary responses or behavior, etc.
+
+The mock devices are mainly for testing the compiler.
