Configuring SAM deploy
======================
Looking for samconfig.toml : Not found
Setting default arguments for 'sam deploy'
=========================================
Stack Name [sam-app]: cors-swagger-1434-1
AWS Region [us-east-1]: us-west-2
#Shows you resources changes to be deployed and require a 'Y' to initiate deploy
Confirm changes before deploy [y/N]: y
#SAM needs permission to be able to create roles to connect to the resources in your template
Allow SAM CLI IAM role creation [Y/n]: y
Save arguments to samconfig.toml [Y/n]: y
Looking for resources needed for deployment: Not found.
Creating the required resources...
Successfully created!
Managed S3 bucket: aws-sam-cli-managed-default-samclisourcebucket-1hbwe4gjysnvb
A different default S3 bucket can be set in samconfig.toml
Saved arguments to config file
Running 'sam deploy' for future deployments will use the parameters saved above.
The above parameters can be changed by modifying samconfig.toml

I think this will get the integration tests passing:
if method == "OPTIONS" and (method not in route.methods or cors_headers["Access-Control-Allow-Origin"] == "*"):

This is probably a better approach:
method, _ = self.get_request_methods_endpoints(request)
if method == "OPTIONS" and self.api.cors:
headers = Headers(cors_headers)
return self.service_response("", headers, 200)

This says something about how httpMethod must be POST.
