Features of PSRule include
- DevOps – Built to support DevOps culture and tools.
- Extensible – Define tests using YAML, JSON, or PowerShell format.
- Reusable – Reuse and share rules across teams or organizations.
Project objectives
- Extensible:
- Provide an execution environment (tools and language) to validate infrastructure code.
- Handling of common concerns such as input/ output/ reporting should be handled by the engine.
- Language must be flexible enough to support a wide range of use cases.
- DevOps:
- Validation should support and enhance DevOps workflows by providing fast feedback in pull requests.
- Allow quality gates to be implemented between environments such development, test, and production.
- Cross-platform:
- A wide range of platforms can be used to author and deploy infrastructure code. PSRule must support rule validation and authoring on Linux, MacOS, and Windows.
- Runs in a Linux container. For continuous integration (CI) systems that do not support PowerShell, run in a container.
- Reusable:
- Validation should plug and play, reusable across teams and organizations.
- Any reusable validation will have exceptions. Rules must be able to be disabled where they are not applicable.

- Rule – A rule definition.
- Exists – Assert that a field or property must exist.
- Match – Assert that the field must match any of the regular expressions.
- AnyOf – Assert that any of the child expressions must be true.
- AllOf – Assert that all of the child expressions must be true.
- Within – Assert that the field must match any of the values.
- TypeOf – Assert that the object must be of a specific type.
- Reason – Return a reason for why the rule failed.
- Recommend – Return a recommendation to resolve the issue and pass the rule.
