I think this tool easy to use, support many assertion methods such as JSON path data, JSON validation, XPath data, โฆ This tool also support for automating API testing and integrating with GitHub.
I find a new API testing tool that is Advanced REST client.
Advanced REST client is very easy to use. But it only for REST client, not SOAP. Itโs simple , itโs suiting to create and test custom HTTP requests which are not very complex.
I tried Paw for this exercise. It has a really nice interface and like Postman, allows the creation of environments and dynamic variables. As you create and send requests the software stores response variables and values and saves them within a project. You can use dynamic variables to chain requests in this way and doing that is quite intuitive.
Although Paw doesnโt have the large user base that Postman and other more established API software (it is a paid mac-only app after all), it has several extensions that can be added on the fly and for instance, allow you to export requests in a lot of different languages and frameworks.
