Wireless Testing Interview Questions And Answers

The most common and important difficulties that should be overcome by testers is testing on multiple types of handsets and automation testing.

How can you overcome them?

As a tester you need to make yourself more aware of the automation services/tools to run tests on mobiles handsets.
A smart mobile simulation program is hooked on to the actual (physical) handset at 'device anywhere' site. Companies pay per use or a monthly fee. The UI is like that of a mobile simulator, but the tests run on a phone.
The beauty lies in the variety of mobile phones they offer. I'm no way connected to device anywhere company but I'm a customer who is benefiting from their service. Awesome part is: automation testing on physical devices, how nice does it get?

Knowledge of popular handset used by public will also be of immense help to test mobile applications

The technology used will determine the type of test environment and tools that we need.

* WAP
* Bluetooth, etc.
* XML, WML
* Security protocols

Tools

* WAP Simulators by hardware vendor: Nokia, Ericsson, Motorola
* Capture/Playback - such as TestPartner by Compuware
* Performance Testing - such as QA Load Compuware

Wireless test executive is an easy-to-use graphic interface for controlling test selection, execution, and runtime options. Tests are displayed in a hierarchical list where each entry represents one test.Test Objects are a key component of the Test Executive Architecture.The Test Objects operate with the Test Executive through a standard interface that is provided by the Test Executive DLL.

Its giving enough load to the process. Suppose a user using the wireles interface for communication, which it is many-many communicator.

1. Check the interface behaves once another communicator is in request(make a call to a
interface, which is busy in communcating with another interface).

2. Check the Wireless interface performance on invoking the another application( Reminder, Alaram invoked on call, Message received, low battery ect..)

Levels of testing:
1.Usability Testing
2.Network Performance Testing
3.Server-Side Testing
4.Automating Unit Testing

1. Check that the Wireless Network Adapter is on and verified by LED glow.
2. Check that the Wireless Network Adapter is suited for the different OS.
3. Check the Wireless Network Adapter is able to pass Installation Testing.
4. Check that the Wireless Network Adapter is able to configure.
5. Check the data flows(in/out) functions for the Wireless Network Adapter.
6. Check the flow rate of data and should not breakup.
7. Check the Time delay taken for every process.
8. Data Transmission should not be freeze at any situation.

RACAL is Base station emulator, using this we can test all mobile use cases in the controlled environment.

procedure of battery testing

battery backup test for idle mode
1. fully charge the battery
2. make sure no calls should be made on DuT
3. start timer when fully charget
4. wait until the battery drain out fully
battery backup test for dedicated mode
1 again fully charge the battery
2 make a call to a test phone from DuT
3. start timer when call is connected
4. wait untill the battery is fully drain out
5. match all the readings from user manual and check the battery leakage

There are testlabs to test the voice over wireless testing. Otherwise you can use two of ur test mobiles and can put any operators simcard just like ur own mobile and can test it. Most of the companies provide some operators simcards to test.

I think we must consider the following aspect:
1. Unauthorised access/Guest access
2. Firewalls
3. Concurrent connections

Basically Call module should be covered for wireless testing, after that all the applications should be tested how those applications behave when a call is received being in that application.

2G and 3 G is a family of standards for mobile telecommunications defined by the International Telecommunication Union,which includes GSM EDGE, UMTS, and CDMA2000 as well as DECT and WiMAX. Services include wide-area wireless voice telephone, video calls, and wireless data, all in a mobile environment.

2G Stands for second generation mobile telephony standards, where 3G defined the third generation mobile telephony standards to facilitate growth, increase bandwidth, and support more diverse applications.For example, GSM (the current most popular cellular phone standard) could deliver not only voice, but also circuit-switched data at download rates up to 14.4 kbps. But to support mobile multimedia applications, 3G had to deliver packet-switched data with better spectral efficiency, at far greater bandwidths.

I just came across this url and could not help myself to comment on this. Your question looks little vague. I mean, are you talking about network level protocols or application level protocols. Or is it related to OBEX protocol implementation in Mobile Apps. Actually the same TCP/IP concepts go in mobile apps also, but when it comes down to browsing apps/downloading apps, it is generally done via WAP gateway (Not WAP Server which generally people confuse with). WAP is a standard defined to serve as a common platform as we cannot directly hook on from normal TCP/IP network to a mobile network. But it is definitely possible to call, SMS, sending mail from any browser to a mobile device, and vice versa. So how does this happen? Also are you talking about what happens at the server end, after the gateway or before that. Also, which carier network are you referring to GSM/CDMA. If I have sensed right it is "OBEX" you are referring to.

Mobile Tester Should know about the
1. Mobile Technology
2. Development Technology
3. Mobile Platform(OS)
4. Knowledge on Device Supporting Tools.
5. Mobile Protocols
