- Core functionality of the app is working as expected.
- UI of the app is as expected like all elements are aligned properly; there is no truncation of element or text etc. UI should be consistent across all screens of AUT (Application under test).
- Touch area of all touchable elements is big enough so that normal user does not feel any problem in touching them.
- Font size of all the text should be optimum i.e. neither too small nor too big so that normal user is able to read it with ease.
- UI remains consistent on rotating the device. If user is reading some text then on rotating device text/list should not scroll to top i.e. it should maintain current position.
- If on rotating device there is some extra space then elements should be automatically adjusted accordingly i.e. either size of the elements should be increased or other elements (for which user was required to scroll earlier) should be displayed on the screen.
- Smart phones automatically handle most of the suspend resume functionality automatically but testers should also test it especially in case of audio & video play.
- If AUT is accessing any third party / inbuilt app like contacts, messaging, email, facebook etc. then it should transfer required data properly and on coming back to AUT should be smooth and should come back to the same screen from where user left.
- If AUT needs to download very large data then it is recommended to be downloaded asynchronously i.e. initial chunks of data should be downloaded first and user should be able to read text or scroll list while rest of the data is being downloaded.
- If AUT has some authentication screen like login screen then keep an eye on network log to make sure that AUT does not pass username & password in plain text. Also after logout such authentication tokens / session id should be deleted.
- If AUT is saving some personal information like authentication token, password, credit card then it should be saved in encrypted form.
- Instrumentation should be used to check memory leaks and memory consumed by AUT during run.
- App should support all the orientation of the device. If not, then both variations of the orientation (in case of portrait mode – upside-down).
- On uninstalling, all the files related to the AUT should get deleted and other apps should remain unaffected.
- If AUT displays badge on the app icon then it should display correct count and on every update it should be updated accordingly.
- If AUT has popover then popover should not have any explicit close button. Instead it should disappear when user taps on any item on it and corresponding action should take place or user tab anywhere else on screen.
- All navigation should be self-explanatory like Back button should take user to logically previous page, Cancel button should cancel current operation etc.
- If AUT has scroll-able form like screen then currently focused text field should be visible to user i.e. keyboard should not hide it. And on hiding keyboard screen should be adjusted accordingly.
- Navigation from one screen to another or screen rotation should not be abrupt. AUT should animate components smoothly.
- Switching between Wi-Fi and mobile network should not affect functionality of AUT. Also if device’s Wi-Fi and network are disabled by user (i.e. Airplane mode) and AUT tries to make any network call then AUT should be display appropriate error message to user, asking him to enable Wi-Fi. In such scenario AUT should not display loading bar before should error message.
- Battery consumption should be under control when AUT is running.
- One of the most important aspects is performance of the AUT. AUT should not be very slow otherwise user will move to other similar apps. AUT should keep user engaged and should display results as quickly as possible.
- Testing AUT using different network connectivity like Wi-Fi, 3G, 2G etc.
- AUT should handle network failure scenario gracefully e.g. device loses network while AUT is downloading some content. In such scenario a proper error message should be displayed after timeout i.e. AUT should not keep displaying loading screen indefinitely.
- Special testing should be done to verify how AUT handles foreign characters and special characters.
- If new version of AUT is available then user should be notified about the update and AUT should be updated smoothly without deleting existing user’s data and preferences.
