When users launch an AWS CloudFormation template, they get charged for AWS usage even if the stack fails and the instance runs for a very brief time. For this reason, you need to test your Partner Solution thoroughly before we publish it. Testing becomes even more important for complex stacks and expensive stacks (such as those that use the X1 instance type).

When you’re ready to test your Partner Solution, use the navigation links at left to learn how to manually test and debug your Partner Solution. In addition, we provide an automated testing tool called TaskCat that helps validate your templates.
