React Native: How to setup automated integration tests?

I'm new to testing and I've been given a task to set up and write automated integration tests for React-Native app for both iOS and Android. I'm having a serious trouble setting up integration tests. What frameworks should i use? I've found some tutorials but they felt mostly outdated. Is using Appium with Travis CI viable? I've found some examples using Mocha and Chai to write tests. (http://ift.tt/2n2Amhm this seems like the best one). I really appreciate any help you can offer.
