How do you test your mobile applications? James Montemagno talk to Carl and Richard about various testing approaches for mobile apps. James talks about the Xamarin Test Cloud with thousands of different devices you can test against... for a fee of course. This leads to a conversation about automating UI testing, testing against local devices and only going to the cloud when you're ready to test on a larger diversity of phones. James also talks about the broadening range of devices out there, not just phones but tablets, wearables and IoT. Everything needs testing, and there are tools to make it easier!
