Introducing Testfully's Google Chrome Extension

## Introduction --- To be able to run your tests in browser, Testfully needs to send HTTP requests to your API and because Testfully and your API are available via two different domains, modern browsers like Google Chrome do a check known as [Cross-origin resource sharing (CORS)]( Although this is a great idea and makes web a more secure platform, it comes with a restriction: Most APIs leverage CORS and only serve browser-based requests that are originated from their own domain. As a result of this, Testfully won't be able to run tests in browser for that API. One solution to solve this problem would be to accept requests originated from but that requires changing your API code and deploying it.

Testfully’s Google Chrome extension allows you to run your tests in browser and get result, even if your API does not support CORS.

How It Works

Simply install Testfully’s Chrome Extension and you can run tests in your browser straight away. You don’t need to change anything in your tests, in your browser settings or in your API.
