API testing, in its usual definition of the process of testing backend logic, is not a topic of this article. Here, it is only shown how to check HTTP requests sent by the client in the context of frontend end-to-end testing by a frontend testing tool.

If your task is to perform API testing different from checking schema on the client side, you are free to choose any other tool.

Anyway, Dredd looks like a project that is not supported, with the latest version released in 2021 (almost two years ago). I can suggest to take a look at https://pactumjs.github.io/ for modern API testing tool on JavaScript.
