119Using a Tap-By-Location Helper for Working With Unresponsive Elements
Sometimes, finding an element isn't enough to tap on it. You call the element.click() command, but nothing happens! By building a tap-by-location helper, you might be able to get things working agian, especially if the problem is that you need to tap somewhere other than the midpoint of your element.

118Testing Real-Time User Interaction Using Multiple Simultaneous Appium Sessions
Many apps are not 'single-player,' so to speak. They involve the interaction of multiple users, sometimes in real time. Classic examples would be ride hailing, food delivery, or chat apps. While it's possible to mock out all except one of the parties, to get full end-to-end coverage of these scenarios, it can be useful to run multiple simultaneous Appium sessions, on different devices, to act out the various flows for the various participants, all just as it would happen in an actual use case.

104Simulating Different Network Conditions For Virtual Devices
When testing your mobile app's behavior, it's important not to assume fast or even decent internet connectivity to the user's device. One way of seeing how your app behaves in situations where the network conditions are poor is to simulate those conditions locally, either for manual testing or for use in a build scenario.
