About TaskCat

TaskCat tests AWS CloudFormation templates. It deploys your template in several AWS Regions and produces a report that grades each region as pass or fail, so you can see whether a template works wherever you intend to use it. The listing name Aws Ia refers to the aws-ia team that develops it.

You choose the regions and the number of Availability Zones to include and supply parameter values from your template. TaskCat is implemented as a Python class that you import, instantiate and run, which makes it straightforward to script and to fit into continuous integration. It was originally built by the aws-ia team to test templates that deploy workloads on AWS, and is available to anyone validating custom templates.

Documentation is hosted on GitHub Pages and the package is published on PyPI. It is released under the Apache-2.0 licence.
