MoQuality's Barista is a visual test editor that makes it easy to create, edit and run automated UI tests for native mobile apps. Although test creation using Barista is done using the web-browser, you need to install the Barista Agent that runs in the background on your PC or Mac.
To create or edit tests you need to have the barista-agent installed and running. You can do so with:
npm install -g barista-agent barista start
