Stuboto
Stub boto3 clients to avoid hitting real AWS endpoints in tests.
Usage
You can use Stuboto instances as if they were botocore.stub.Stubber:
import boto3
from stuboto import Stuboto
def test_create_bucket():
s3 = boto3.client("s3")
stubber = Stuboto(s3)
stubber.activate()
response = {"Location": "my-bucket"}
expected_params = {"Bucket": "my-bucket", "ACL": "private"}
stubber.add_response("create_bucket", response, expected_params)
service_response = s3.create_bucket(Bucket="my-bucket", ACL="private")
assert service_response == responseStuboto instances are decorated with all the same methods as the original boto3 client so you can also stub responses with the arguably more readable:
import boto3
from stuboto import Stuboto
def test_create_bucket():
s3 = boto3.client("s3")
stubber = Stuboto(s3)
stubber.activate()
response = stubber.create_bucket(Bucket="my-bucket", ACL="private").add_response(
Location="my-bucket"
)
service_response = s3.create_bucket(Bucket="my-bucket", ACL="private")
assert service_response == responsebotocore.stub.Stubber documentation suggests:
It should be noted, however, that while missing attributes are often considered correct, your code may not function properly if you leave them out. Therefore you should always fill in every value you see in a typical response for your particular request.
But I won't tell anybody if you leave some values out in favor of writing more readable tests.
Installation
pip install stuboto
