What is probitas-info?

This Claude skill provides comprehensive information and technical guidance on the Probitas framework, a scenario-based end-to-end (E2E) testing tool specifically designed for backend services. It helps developers and QA engineers understand how to leverage its built-in clients for HTTP, gRPC, SQL, and message queues to create readable, maintainable, and automated test scenarios with fluent assertions and automatic resource cleanup.

When should I use probitas-info?

probitas-info is useful in the following scenarios: • Understanding the core architecture and 'scenario-based' testing philosophy of the Probitas framework. • Comparing Probitas with other backend testing frameworks to evaluate its features like built-in clients and auto-cleanup. • Quickly identifying the appropriate factory functions for various protocols including PostgreSQL, Redis, MongoDB, and RabbitMQ. • Referencing code examples and API documentation patterns for setting up complex backend integration tests. • Onboarding team members to the Probitas ecosystem by explaining its 'batteries-included' features like faker and spies.

export default scenario("API Test", { tags: ["http"] })
  .resource("http", () =>
    client.http.createHttpClient({
      url: Deno.env.get("API_URL") ?? "http://localhost:8080",
    }))
  .step("GET /users", async (ctx) => {
    const res = await ctx.resources.http.get("/users");
    expect(res).toBeOk().toHaveStatus(200);
  })
  .build();
