Validate AWS Serverless Application Model (SAM) templates with CloudFormation Linter to speed up development

AWS CloudFormation announces support for CloudFormation Linter (cfn-lint) in AWS Serverless Application Model Command Line Interface (AWS SAM CLI). The cfn-lint tool validates your SAM JSON/YAML template against CloudFormation-based rules, and returns diagnostic error messages. With this launch, you can use an optional parameter —lint in sam validate command to run cfn-lint validations on your SAM JSON/YAML templates.
