How to Test a Mobile Application?

At the beginning you should check the following:

•  There are enough devices for testing (according to the target market)
• All the project procedures were agreed upon (understand that everything is ready, a development cycle, deadlines, a team was hired)
• The app follows the guidelines
• The app works in different environments
• The app works correctly with external and internal requests
• Power consumption (like an ordinary user)
• Tests for automation are chosen (when enough manual ones have already been written)

A list of iPhone test cases:

• Rechecking functionality where the most critical defects were previously found (regression testing)
• Functionality check on correct data (current date, short names, etc.)
• Checking for incorrect values (for example, empty fields, long names, setting a date on the phone in the past, etc.)
• Checking the application interface for compliance with Apple (Human interface guidelines for iPhone/iPad)
• App performance and interface response speed (iPhone 2g is used)
• Usability tests
• Test for compatibility with other iPhone applications/functionality (alarm, timer, reminders, incoming call, SMS)
• Testing application settings, if they are applied correctly
• Search for possible crash spots and reasons for their occurrence
• Correct operation of the application when using wi-fi (including disconnection, no connection)
• Checking for the correct work of the application with the iPhone memory (memory leaks)
• Checking if the sound does not disappear when connecting headphones
• Application behavior when iPhone goes to sleep mode
• Application operation with an accelerometer (screen rotation according to the position of the iPhone, using the accelerometer function to receive data by the application)
• Localization testing (supported by the app)

• Verification of the correct operation of the application with the iPhone camera (if such functionality is supported), as well as the correct operation of the application with the iPod.
• Quick “clicks” on interface elements (navigating through categories, navigating through records within a category)
• If there is a lengthy workflow – conduct it all (like long programs in Yoga) in real time
• If there is a ready-made list and a field for inputting parameters, then check the behavior when a hint from the dictionary appears in the field, and at the same time you click on an entry in the list <> hint. there may be conflicts between the hint of the iPhone and the real choice.
• Content verification: adequate image size (up to 1MB) and sufficient quality. Additionally, look at iPhone4 (higher resolution) + see MobileHIG.pdf chapter 11 for image resolution requirements.
• GUI: icons correspond to what they relate to (help – question mark, settings – gear, etc.), new windows smoothly open on the right, there is a loading icon if a long process occurs)
• The presence of the Game Over screen and the correct links on it – for game projects

Multiplayer Games

• the correctness of the connection of players (for example, writing off the balance only after connecting)
• time lags
• connection through different networks
• correct behavior when disconnecting players
• connecting bots (if used)

Conformance Testing

• Protocol testing
• Safety/Security testing
• SIM card testing
• Radio Frequency (RF) testing
• Audio Tests
• Specific Absorption Tests

And More

• Physical/virtual keyboard
• Testing updates and installation
• Paid content: prices match the content, purchases of 2 types (restorable and non-restorable (credits)) – testing the restoring purchases linked to the account (reinstallation/update/another device); there must be a choice from the current progress and saved in the account.
• Advertising: must not overlap elements, must have an available close button (And if the button has not yet appeared, then the countdown before that).
• Globalization: everything that is needed changes and it happens correctly. Protection from taking advantage of date and time manipulation.
• Copy and paste from and to the application.
