The record

Purpose: YAKS is a framework for cloud-native behavior-driven development testing on Kubernetes.
Execution model: Tests run as Kubernetes pods after the YAKS operator prepares a test runtime from a Test custom resource.
Test language: YAKS tests use BDD feature specifications written in Gherkin syntax.
CLI: The yaks CLI installs the operator and runs tests on a Kubernetes cluster.
HTTP integration: The yaks-http module calls HTTP REST endpoints, verifies responses, and can provide an HTTP service that receives requests and simulates responses.
Messaging integrations: Predefined steps support HTTP REST, JMS, Kafka, and Knative eventing transports.
Camel integration: The yaks-camel module creates, starts, and stops Apache Camel routes and exposes more than 300 Camel components for testing.
Camel K: YAKS provides bindings for creating and verifying Apache Camel K integrations running on Kubernetes or OpenShift.
OpenAPI: The yaks-openapi module imports OpenAPI specifications and uses defined operations and test data to call HTTP REST endpoints.
Secrets: Tests can load credentials and connection URLs from Kubernetes secrets selected with YAKS labels.
Security controls: Managing custom resources requires Kubernetes roles and role bindings for the yaks-viewer and yaks-operator service accounts.
Requirements: YAKS requires access to a Kubernetes or OpenShift cluster, and administrative rights may be needed to set up roles and custom resources.
Windows support: Full Windows support requires enabling Windows Subsystem for Linux and rebooting the system.
License: The YAKS repository is published under the Apache-2.0 license.
