 This repository uses Appium to run UI tests. The tests live in `__device-tests__` and are written using Appium to run tests against simulators and real devices. To run these you'll need to check off a few things:
 
 -   When running the tests, you'll need to ensure the Metro bundler (`npm run native start`) is not running.

We also recommend using [appium-doctor](https://github.com/appium/appium-doctor) to ensure all of Appium's dependencies are good to go. You don't have to worry about starting the server yourself, the tests handle starting the server on port 4723, just be sure that the port is free or feel free to change the port number in the test file.

It's important to note that when using the relative paths it's not to the project folder but to the appium server, since by default we start up appium in the project root when running the paths appear relative to the root but if you were using another instance of the Appium server the relative path would need to come from there.
