Since moto does not support every AWS service available there is a way to patch boto3 calls until they are supported.
To do so, you need to mock the botocore.client.BaseClient._make_api_call function using mock.patch:
python
import boto3 import botocore from unittest.mock import patch
# Original botocore _make_api_call function orig = botocore.client.BaseClient._make_api_call
# Mocked botocore _make_api_call function def mock_make_api_call(self, operation_name, kwarg): # For example for the Access Analyzer service # As you can see the operation_name has the list_analyzers snake_case form but # we are using the ListAnalyzers form. # Rationale -> https://github.com/boto/botocore/blob/develop/botocore/client.py#L810:L816 if operation_name == 'ListAnalyzers': return { "analyzers": [{ "arn": "ARN", "name": "Test Analyzer" , "status": "Enabled", "findings": 0, "tags":"", "type": "ACCOUNT", "region": "eu-west-1" } ]} # If we don't want to patch the API call return orig(self, operation_name, kwarg)
- def test_list_findings():
client = boto3.client("accessanalyzer")
- with patch('botocore.client.BaseClient._make_api_call', new=mock_make_api_call):
analyzers_list = client.list_analyzers() assert len(analyzers_list["analyzers"]) == 1 # include your assertions here
Note that this does not use Moto, to keep it simple, but if you use any moto-decorators in addition to the patch, the call to orig(self, operation_name, kwarg) will be intercepted by Moto.
