Two types of Test cases are there:
1) Positive Test Cases
2) Negative Test Cases
A) Positive Test Cases are:
1. Installation Testing
2. UI Testing: or Design based Testing
3. Functional Testing
4. Non Functional Testing
5. Performance and load Testing
6. Compatibility and Security Testing
Let’s explain one by one:
1. Installation Testing:
1. Verify all the parts of the mobile are available or not like battery, keypads etc.
2. Verify that the battery is fitted properly.

19) Verify that where is speaker located on mobile.
20) Verify that noise cancelation is available or not.
5. Functional Testing:
1) Verify the touch is working or not if it is a touch mobile.
2) Verify that the key buttons are working or not if it is a keypad mobile.
3) Verify that power on and power off button is working properly or not.
4) Verify that volume increase or decrease button is working properly or not.
5) Verify that camera button is working properly or not if a special button is given on mobile for picture click.
6) Check that mobile front or back camera is working fine.
7) Verify that mobile flash light function is working properly or not.
8) Verify that charging function is working properly or not.
9) Verify that is microphone is working properly or not.
10) Verify that is speaker located on mobile is working properly or not.
11) Verify that noise cancelation function working properly or not
12) Verify that Bluetooth function working properly or not if Bluetooth is available on mobile
13) Verify that Wi-Fi function working properly or not if Wi-Fi function is available on mobile

j) Verify that user get notification when he/she get new message.
6. Non Functional Testing:
1. Test whether the object (a Mobile of in this case) looks like a Mobile (obviously there must be some expected result by which you can Verify and can say -yes this is a Mobile )

7. Performance and load Testing:
1. Put a high amount of pressure on the Mobile for the particular amount of time to do the bend test.
2. Pay particular attention to put stress on a points on the Mobile and Verify that the Mobile continues to perform its function.
3. Run multiple applications at the same time as check that how it performs.
4. Try to open multiple window on the same screen and check the performance
5. Check out the mobile Speed, it must not stuck.
