TaskCat

What TaskCat is

TaskCat is free, open-source software for testing AWS CloudFormation templates. It deploys a template across multiple AWS Regions and reports pass or fail results for each one, either across all Regions or a selected set. Automated checks cover stack validation and resource verification. Runtime parameters can retrieve AWS environment values, generate random values, passwords, or unique IDs, and provide test context. They can also read from AWS Systems Manager Parameter Store and AWS Secrets Manager. Reports may include stack outputs, resource details, and deployment timelines. TaskCat provides both a command-line interface and a Python API. Documentation names GitHub Actions, Jenkins, and AWS CodePipeline integrations. Installation options include PyPI through pip, development installation, and an official Docker image. Prerequisites include Python 3.8 or higher, AWS CLI credentials, Git, and AWS permissions. The guide lists broad testing permissions and recommends narrower policies in production. IAM roles and secure parameter handling are documented, and the project uses an Apache-2.0 license.
