How do I enforce policy-as-code for Load testing using OPA and Conftest?

To enforce policy-as-code for load testing using Open Policy Agent (OPA) and Conftest, you can define your policies in Rego, OPA’s policy language, and then use Conftest to validate that your load testing configurations adhere to those policies. This ensures that your load tests conform to best practices and organizational standards.

The following example illustrates how to set up a simple load testing policy and use Conftest to check a configuration file against that policy.

// Example policy in Rego package load_test # Allow load testing only if the duration is less than 1 hour deny[{"msg": msg}] { input.duration > 3600 msg := "Load test duration exceeds the maximum allowed limit of 1 hour." } # Allow load testing only if the number of virtual users is within acceptable limits deny[{"msg": msg}] { input.virtual_users > 1000 msg := "Number of virtual users exceeds the maximum allowed limit of 1000." } // Example load test configuration file { "duration": 3600, "virtual_users": 500, "test_name": "API Load Test" }
