Uninstall TestGen

This document provides the steps to uninstall an instance of DataOps Data Quality TestGen. The uninstall process deletes all TestGen resources and data.

  • Docker mode — removes the containers, volumes, and images related to TestGen.
  • Pip mode — removes the Python environment, dependencies, and data directories related to TestGen.
  • Kubernetes mode — removes the Helm release and the namespace. The application database is on a separate server, so it is dropped separately.
