Patrole

• Extends the Tempest test framework to cover RBAC-specific Application Programming Interface (API) testing across OpenStack services (test automation).
• Provides parametrized test cases that assert behavior for different user roles and policy rules (RBAC validation).
• Enables operators and developers to verify that OpenStack policy.json or policy-in-code configurations enforce intended permissions (access control compliance).
• Integrates with standard OpenStack testing workflows and Continuous Integration (CI) pipelines for automated policy regression checks (CI/CD integration).
• Supports configuration-driven selection and execution of RBAC tests per service and role set (test suite configuration).

More About Patrole

Patrole is an OpenStack project that extends the Tempest ITF to validate RBAC behavior across OpenStack APIs (security and compliance testing). It focuses on verifying that policy definitions, whether in policy.json files or implemented as policy-in-code, enforce the intended permissions for different user roles in an OpenStack cloud.

The core purpose of Patrole is to give operators, QA teams, and developers a structured way to test that users with specific roles can or cannot perform particular API operations (RBAC validation). By leveraging Tempest’s existing test infrastructure, Patrole adds role awareness and policy assertions on top of standard API tests, allowing a deployment to be checked against its own access control configuration.

Patrole provides a set of parametrized tests that can be executed against various OpenStack services, such as compute, identity, and others that expose policy-governed APIs (OpenStack service testing). These tests are written to exercise API endpoints under different user roles and to verify the expected Hypertext Transfer Protocol (HTTP) response codes or behaviors based on the configured policies. This approach helps detect misconfigurations where a role has more or fewer permissions than intended.

The project integrates into existing OpenStack test workflows by functioning as a Tempest plugin (test framework integration). Deployments that already use Tempest for API and scenario testing can add Patrole to gain RBAC-specific coverage with minimal changes to their tooling. Configuration options allow teams to specify which roles, services, and test sets to run, enabling targeted testing aligned with local policy models.

In enterprise or institutional environments, Patrole is used in CI pipelines and pre-deployment validation to ensure that changes to policy files, role mappings, or service configurations do not introduce unintended access paths (CI/CD and release validation). This is relevant in regulated sectors where repeatable, automated checks of authorization behavior are required for internal controls and audit evidence.

Technically, Patrole operates within the OpenStack and Tempest ecosystem, relying on standard OpenStack authentication and authorization flows (cloud infrastructure). It uses Tempest’s configuration and credential management to obtain tokens for users with different roles, then executes API calls and compares results against expected policy outcomes. Because it is plugin-based, it can coexist with other Tempest plugins and test suites, forming part of a broader verification strategy for OpenStack clouds.

Within a technical directory or catalog, Patrole fits under security and compliance testing for OpenStack-based infrastructure, with specialization in RBAC and policy validation (cloud security testing). It is relevant for teams responsible for OpenStack operations, platform engineering, and security governance that require automated verification of access control behavior across their cloud services.
