  • GitHub repo dredd

    Language-agnostic HTTP API Testing Tool

    Project mention: Front End UI Test Automation With Mock API | | 2021-05-18

    To test the API, I recommend a proper API testing framework that can run a full test suite without you having to write a single test case. In this area, I recommend Dredd and schemathesis. These frameworks will get you covered when it comes to ensuring that the API server complies with the API specification. You may find Dredd a bit confusing at the beginning, in which case I recommend a tutorial I wrote a while ago about testing with Dredd. In addition, you can consider using just-apis, which allows you to define your own test cases for the API in YAML files (so no programming required).
