We can use postman, but our testing are usually endpoints that are easier to test with the browser. So in that vein I created this Chrome Extension that allows you to upload a JSON or Yaml file with all of the endpoints you want to test and produces a report with the response body and other particulars of the calls.

I built this with Stenciljs and Semantic Ui.

I would love feedback of other ideas on how to improve. If you hate it, please be kind :)
