Background

During an internal triage, I found out we need to catch ReadTimeout and ConnectTimeout while sending requests post request. requests.execptions.Timeout will catch both ReadTimeout and ConnectTimeout.

Changes

• Add requests.exceptions.Timeout to default exceptions in output base class
• Update unit test cases.

Testing

• Unit test

./tests/scripts/unit_tests.sh
...
Ran 548 tests in 9.324s

OK

• Rule test

python manage.py lambda test --processor all
...
StreamAlertCLI [INFO]: (61/61) Successful Tests
StreamAlertCLI [INFO]: (33/33) Alert Tests Passed
StreamAlertCLI [INFO]: Completed
