  90. 90. Conducting testing in uncontrolled real-world test conditions (field-based testing) is necessary, especially for a multi-tier mobile application.
  91. 91. Select the right automation test tool for the success of the testing program. Rules of thumb for an ideal tool are:
  92. 92. One tool should support all desired platforms.
  93. 93. The tool should support testing for various screen types, resolutions, and input mechanisms such as touchpad and keypad.
  94. 94. The tool should be connected to the external system to carry out end-to-end testing.
  95. 95. Use the Weighted Device Platform Matrix method to identify the most critical hardware/ platform combination to test. This method will be very useful especially when hardware/ platform combinations are high and time to test is low.
  96. 96. Check the end-to-end functional flow in all possible platforms at least once.
  97. 97. Conduct performance testing, GUI testing, and compatibility testing using actual devices. Even though these tests can be done using emulators, testing with actual devices is recommended.
  98. 98. Measure performance only in realistic conditions of wireless traffic and user load.</li></ul>Installation<br />Un-installation<br />Network Test Cases<br />Voice Call Handling<br />SMS Handling<br />Unmapped keys<br />Application Logo<br />Splash<br />Low Memory<br />User Key Actions<br />Continual Keypad Entry<br />Visual Feedback<br />Exit Application<br />Charger Effect<br />Low Battery<br />Removal of Battery<br />Battery Consumption<br />Application Start/ Restart<br />Application Side Effects<br />External incoming Communication<br />–Infrared / BTH<br />
