|
Situation-based application |
There are specific situations where the deadline to produce text execution results are short and purchasing the required mobile devices may be not possible. Thereby it might be necessary to use the emulator/simulator in these circumstances for testing the relevant mobile applications which need to be tested.
|
The real device allows the testers to test almost all the real time scenarios which can be tested for the mobile applications. These devices are operated using fingers and simulate real-life usage. They also help in situation Real context: is it easy to use the app on the train, or while walking down the street? The situation about in bright sunlight or in the rain? |
|
Feeling of closeness towards the real handheld devices |
The wide gamut of mobile devices creates the problems, whereby the testers are not confident about which mobile devices to invest in for testing, considering the budget constraints. Emulator/simulator (s) is tailor made for this type of situation(s). |
The real device allows the testers to test even usability issues like the look and feel of the application, color resolution of the screen, whether the picture is bright or not under both day and night conditions and so on. |
|
Ease of availability |
Emulator/simulator(s) are in most cases open and free software which can be very easily downloaded from Internet and ready to be tested for. |
The real devices allow stringent performance testing issues like working with a real time transport application for 15 hours continuously which cannot be successfully simulated by the emulators. |
|
Ease of opening an Web application through URL |
It is easier to do web application testing when it comes to opening the web application. The user just needs to copy and paste the application URL. |
Testing on real devices provides more in terms of reliability. |
|
Capturing screenshots of the situations where defects appear |
Capturing issue of screenshots over simulator is very easy with the simulator since we just need to use Microsoft office facilities. |
Testing with real world devices is very helpful in terms of interoperability testing. |
|
Simulation of validation of battery scenarios |
The emulator/simulators are not able to simulate the battery issues. |
Real world devices can easily perform the same. |
|
Validation of incoming interrupts |
The emulator/simulators are not able to simulate the incoming interrupts for SMS as well as the incoming calls. |
Real world devices can easily simulates incoming interrupts. |
|
Validation of exact color displays |
The emulator/simulator is not able to properly emulate/simulate the exact color display of the devices when the real device is in sunlight or in black. |
Real world devices can easily simulates the exact color displays. |
|
Validation of the performance |
The performance of the emulator/simulator tends to be slower than the original devices at times. |
The original devices tend to perform faster than the emulator or the simulators. |
|
Simulating memory related issues |
The memory available at the emulator/simulator tends to be far more than the real devices so this may create misconception for the users who would be using the same validations. |
