    RestSequence
    RestSequence is a no-code platform that allows users to create end-to-end product test workflows by using underlying product-under-test APIs. It enables users to create, manage, and execute test cases and scenarios efficiently. By harnessing the power of their application's Swagger API collection, RestSequence empowers users to quickly design and test scenarios, guaranteeing superb application performance and reliability. With RestSequence, you can onboard generated test scenarios, integrate them into your CI/CD pipeline, and run them on nightly, weekly, or release builds. The best part is that the output file generated once using RestSequence can be used for future testing scenarios without making any changes. RestSequence reads and parses API details (method, URL, payload, request body, etc.) from a Swagger specification file. It tests each API endpoint for correct responses, status codes, required fields, and invalid data, tracking the created resources during test execution.

    Go REST

    Go REST

    Go REST

    Go REST is a GraphQL and RESTful API platform for testing and prototyping that delivers fake data with real responses, available 24/7 via public endpoints for users, posts, comments, and todos. It supports multiple API versions with full search on all fields, pagination (page and per_page), rate-limiting headers, and response format negotiation. Standard HTTP verbs are supported, and mutating requests require an access token via HTTP Bearer or query parameter. Nested resources let you retrieve related data, user posts, post comments, and user todos, while request and response logging, customizable rate limit,s and daily data resets ensure a clean testing environment. A GraphQL endpoint at /public/v2/graphql offers schema-driven queries and mutations.
