We often do mobile application testing on three platforms IOS, Android and Windows. Share your experience as in the difference you see using these platforms and are there a basic step or approach for each of them.

When there are different mobile OS are available for testing then one thinks about the different UI and user experience provided by them. An application's look and feel changes dramatically when tailor made for different OS platforms. Example: Facebook on Windows Mobile OS, iOS and android is completely different, in that cases the gesture testing, UI transitions are to be considered in mind as it might become too flashy for customer/users. Using what’s App on windows mobile OS gives you a completely different experience all together as compared to the Android, when user sends any voice note from windows os the "mic" icon is displayed on the left hand side however in android it is available on the right. Although it is not a bug but keeping these things in mind can help in making an approach towards testing the products according to the platforms.

Mobile application testing requires testing in all OS available like windows, Android, IOS, but major thing lies in finding the difference in each of them. Same application behaves differently in different OS. These differences are in User Interface, Security Issues, and Speed etc. When we talk about Android, applications are more user friendly compared to windows. Applications like watsapp, Facebook can be customized in android in a much user friendly way unlike windows. When we talk about mapping feature Windows phone uses Bing maps whereas android and IOS use Google maps. This difference creates a different user experience for each of them. This application is found best in windows when we consider Indian maps. While android and IOS Google maps are found better when we consider maps around the globe. Windows OS is best for corporate people who rely on Office to work on their assignments away from office. They provide an instant access to important documents. Considering design issues IOS has such a simple design that even toddlers successfully navigate between menus.

These all issues need to consider as first approach for testing as compatibility issues exist with same application across different OS.

Mobile application testing is a very challenging and dynamic job. Applications need to be tested on different browsers combinations. It is very difficult to say that if a particular and tested application works properly on a device than it will also work as same on another device even it is the same as previous one. This could be because of memory, resolution, hardware and screen resolution. Mobile application must satisfy the industry standards and should be accepted globally without any error.

Many types of testing needs to be done on mobile application as, usability testing, compatibility testing, interface testing, services testing, low level resource testing, performance testing, operational testing, security testing.

The main challenges and risks in mobile applications testing can be mitigated by adopting various tools and strategy. The tools help us in measuring security and compatibility compliances.
