Spec sheet

Purpose

Cloud-Radar is a Python module for testing AWS CloudFormation templates and stacks.Read 7 Oct 2026 · github.com

Intended users

The project is for people writing unit or functional tests for AWS CloudFormation templates and stacks in Python.Read 7 Oct 2026 · github.com

Integrations

The project is built with Taskcat and cfn_tools from cfn-flip; Taskcat is used for functional testing.Read 4 Oct 2026 · github.com

Support

The README directs users to GitHub issues to report bugs and request features, and names Levi as the contact.Read 4 Oct 2026 · github.com

License

The project is distributed under the Apache-2.0 license.Read 7 Oct 2026 · github.com

AWS resource access

Functional tests can interact with deployed resources using boto3 and control stack lifecycle, including testing whether resources are retained after stack deletion.Read 7 Oct 2026 · github.com

Dependencies

The project is built with Taskcat and cfn_tools from cfn-flip; the E2E testing feature requires optional extra dependencies.Read 7 Oct 2026 · github.com

Functional tests

Cloud-Radar wraps Taskcat to help write functional tests for CloudFormation deployments across AWS Regions.Read 7 Oct 2026 · github.com

Install

The README documents installation with pip install cloud-radar and an optional cloud-radar[e2e] extra for functional testing.Read 4 Oct 2026 · github.com

Installation

The maker documents installation with pip as cloud-radar and lists Python 3.8 or newer as a prerequisite.Read 7 Oct 2026 · github.com

Known gaps

The roadmap lists incomplete pseudo parameter functionality, references to conditionally removed resources, and updating a stack instance in Taskcat as remaining work.Read 7 Oct 2026 · github.com

Known limits

The README says not all Taskcat or CloudFormation features may be supported and lists incomplete pseudo-parameter functionality and resource references affected by conditionals on its roadmap.Read 4 Oct 2026 · github.com

Local testing

The maker says unit tests can run locally without AWS credentials.Read 7 Oct 2026 · github.com

Maturity

PyPI classifies the package as Pre-Alpha.Read 7 Oct 2026 · pypi.org

Requirement

Cloud-Radar requires Python >= 3.8.Read 4 Oct 2026 · github.com

Template support

Unit testing supports a subset of CloudFormation transforms, focused on AWS::LanguageExtensions, including Fn::ForEach and extended Fn::FindInMap behavior.Read 7 Oct 2026 · github.com

Testing limitation

For unit tests, Ref and GetAtt return placeholder strings by default rather than realistic AWS resource values; template metadata can supply test values.Read 7 Oct 2026 · github.com

Unit tests

It renders templates with a chosen region and parameters so tests can check conditions, conditional resources, resource properties, and names generated with !Sub.Read 7 Oct 2026 · github.com
