Mustard Results is a Chrome extension developed by watson.mattc that aims to simplify manual testing with the Mustard Results server. This extension is specifically designed for users who need to perform manual testing from within their browser.

Mustard Results is built on Ruby on Rails and serves as a multi-environment test results server. It collects test results from various related tests, such as IE Cross Browser or Mobile Testing on Multiple Devices, and groups them for easy analysis.

With the Mustard Results extension, users can conveniently perform manual testing by displaying test steps directly within the browser. The extension also allows users to write test results and attach screenshots, making it easier to document and track testing progress.
