![]() One problem encountered by many apps at some point in their history is a memory leak. There's too much to dig into in one edition, so let's focus on a simple example involving memory usage. Finally, is an integer denoting the number of seconds Appium will poll for performance data if it is not immediately available. For the time being, they are: cpuinfo, memoryinfo, batteryinfo, and networkinfo. There is another handy driver command ( getSupportedPerformanceDataTypes) which tells you which types are valid. is what kind of performance data you want. Here, is the package of your AUT (or any other app you wish to profile). Building on the wealth of information that comes via adb dumpsys, Appium provides a succinct overview of all aspects of your app's performance via the getPerformanceData command. Luckily for Appium users, all kinds of interesting performance data is available to you via the Appium API-well, on Android at least. ![]() Engaging in performance testing is therefore a way to be a good citizen of the app ecosystem, not just to ensure the snappiest experience for your own users. Mobile apps also have the potential not only to create a bad experience for the user while the app is open, but by hogging CPU or memory, could shorten the battery life or cause other applications to run slowly. Mobile apps, more than desktop apps, run in very resource-constrained environments. Performance is simply how responsive your app is to the user, and can include a variety of specific factors, from network request time to CPU an d memory usage. One of these other dimensions is performance. ![]() Functional testing is very important, but there are other dimensions of the user experience that are equally worth checking via automated means in your build. What I mean is that people usually check the state of an app's UI to ensure that the app's features are working correctly. Traditionally, Appium is used to make functional verifications of mobile apps.
