Hm, looks like policy() in LambdaResponses is not tested in server mode..

Thanks for all of the work @lhufnagel !

I tried upgrading to 1.3.7 and found some sort of issue with the monkey patching that occurs only when other tests (without moto) are run first. I suspect something is getting imported that prevents the patching. When I run just test files with moto imported, they all pass. When I run my whole test suite, or even just two files (one without moto, but that still imports some of our project that has boto3 imports), provided the test without moto runs first, the moto tests will fail with IAM permission issues.

I am still seeing error:
botocore.exceptions.ClientError: An error occurred (InvalidAccessKeyId) when calling the CreateBucket operation: The AWS Access Key Id you provided does not exist in our records.

Version I am using:
boto==2.49.0
boto3==1.9.38
botocore==1.12.38
moto==1.3.7
