See #290 (comment).
Currently tests are cumbersome to write and actually we probably don't want to test which API calls are made but what Spans would result in most cases. For this a SDK with in-memory exporter would be better than using unittest.mock.

I don't think this is actually done. #306 fixed that for wsgi and Flask, but there are other cases where mock is used:

opentelemetry-python/ext/opentelemetry-ext-http-requests/tests/test_requests_integration.py

Line 34 in c8b336d

self.get_tracer_patcher = mock.patch.object(

opentelemetry-python/ext/opentelemetry-ext-dbapi/tests/test_dbapi_integration.py

Line 26 in c8b336d

self.start_current_span_patcher = mock.patch.object(

opentelemetry-python/ext/opentelemetry-ext-mysql/tests/test_mysql_integration.py

Line 28 in c8b336d

start_current_span_patcher = mock.patch.object(
