On the project we use some of AWS services like AWS Lambda, EC2, AWS API Gateway, ElastiCache, etc. Also we have CloudFormation template which describes whole our infrastructure. As the project is developed we begin to use some new AWS services or change configuration of some which are already used. Also with that we should to keep our CloudFormation template up to date.

And here we face with issue that we need to be sure that our CloudFormation template is valid, correct and that we can use it for creation of infrastructure if it will be needed. In such case we need something like continuous testing for our template. Which approaches are more appropriate for that?

Should we configure automatic creation of stack from our CloudFormation template as part of continuous integration process and to track template changes in our repository? Or there are better solutions?
