ClickHouse, an open-source relational database management system, is being used as a target for automated tests through its new Terraform provider. The goal is to provide a simple, cost-efficient, and isolated testing environment for ClickHouse Cloud services. Terraform allows users to define infrastructure as code using a declarative configuration language. A ClickHouse Cloud service can be provisioned using the Terraform provider with variables such as organization ID, token key, token secret, service name, and service password. The service is ephemeral, meaning it exists only during the test run, reducing costs and complexity. The CI/CD workflow in Github actions provisions a new service for each test run, allowing tests to be isolated from each other and reducing conflicts between resources. This approach enables high-quality clients to be provided to users while minimizing costs and improving observability.
