Convert Your OpenAPI Specs Into Runnable Test Cases

Why Rester?

Reduce mobile app crashes.

Rester helps you generate rock solid test suite to make sure you APIs are always working as written in spec. Your API specs are the single source of truth for your system for all clients. Rester intelligently parses those specs and generates test cases covering various scenarios automatically. All you have to do is edit the test data as you see fit and run test cases.
90% of all mobiles crashes are related to APIs sending wrong data types. Rester automatically generates the assertions for the datatypes defined on your specfiles.

No need to write code.

Spending hours writing API tests with a scripting language? No more. Rester can generate the tests with visual form filling and drag-and-drop. Use form-filling style UI to add appropriate data for the test cases.

Sharable reports and collaborative testing.

Share report link with your dev team instantly to speed up the bug identifying and fixing process. All reports are sharable web links that give you complete information about the request/response data to better identify the scenario.
