Interview Questions on Mobile App Testing

2. What is MT SMS Message? 

In general terms, if you send any SMS message and if you get SMS response for that message, then the sending message is called Message Originate(MO) and the response SMS message you receive is Message Terminate(MT).
 

3. What is MO SMS Message? 

Mo SMS Message means mobile originated SMS, i.e. the sms is composed and sent from the Handset Under Test
 

4. Explain what is actual mobile testing and in realtime how this testing happens? 

Mobile Testing:
Now a days,mobile market i s growing with a gr8 speed.So many of the vendors is starting developing the applications which runs on a mobile device.The ppl in countries like U.S,U.K,Europe are using smart phones which have similar functionality like the PC.If we want to login into Yahoo messenger we should have a PC,but now Yahoo messenger is developed for the mobiles also.So it is very comfortable to the users who wants to use this kind of applications from their place on the mobile device,instead using a PC.
Now how yahoo is working on different mobile phones,n how the UI should be tested by the testers.
 

5. What is the difference between User Agent and Simulator? 

User Agent identifies the mobile internals i.e. Make,Model,Resolution ect.User Agent is mandatory while downloading appropriate contents onto mobile, whereas a simulator is used to test the downloading process using various user agents to check whether a device is recognized and specific content/build is sent through OTA.
 

6. What is the difference between WAP testing and Web testing? 

WAP Testing: Is testing the WAP (Wireless Application Protocol) used in network applications.
Web Testing: Is mainly related to testing the web applications such as portals and websites.
 

7. What is the difference between Simulator and Emulator? 

Simulator is the electronic network simulation equipment or a base station equipment for CDMA network/CDMA mobile phones and it is CISCO programmed.It helps in latching home network without roaming services and can make VOICE,SMS,DATA calls especially where there is no roaming facility to test the handset. The CDMA Frequency like 800/900,1800/1900 which do not support in Asia and Europe,can make them live! with the help of this Simulator, the highest capacity of the simulator depends of the manufacturer of the box, may be up to 2400-MHz. It has to be configured both in the box as well as in mobile phones. As per the box capacity it can connect only limited count of mobile phones at one network within a range of 10 meters. This was just brief...
Emulator is a software to test mobile application without a live handset.
 

8. How to know , which are the bands (850,900,1800,1900) a mobile device supports? 

The genrals bands supported by phone are UMTS / HSDPA / HSUPA devices operate in the UMTS frequency bands 800/850/1900/2100 or 850/1700/1900/2100 MHz:
2100 (downlink) / 1900 (uplink) for Europe, Africa, Australia, New Zealand, Asia (including South Korea and Japan) and Brazil (usually referred simply as UMTS2100)
1900 for North and South America2100 (downlink) / 1700 (uplink) for T-Mobile USA and others, called AWS Band (usually referred simply as UMTS1700)
900 for Australia (Optus and Vodafone Australia in rural areas) and in the future in countries that currently use GSM900
850 for North and South America, Australia (NextG), New Zealand (Telecom)
800 for Japan (NTT DoCoMo in rural areas)
Note that being UMTS / HSDPA / HSUPA quad band doesn't mean that phone is a GSM / GPRS / EDGE quad band. However nearly all HSUPA quad band devices are EDGE quad band too.
 
Five and Six band phones (800/850/900/1700/1900/2100) are possible but none have been announced.
 
1st way to find: go to UI settings of BAND SETTING and check the bands avaliable to select which gives the details about the bands supported byy the phone.
 
2nd way to find: if there is no options to view the band settings then we can connect the phone to the simultor and check if the phone if phone latches to the network at that band.
 
as there are hardly 10 bands which a phone can support using that we can ckeck the bands supported by the phone with the help of simulator.
 
3rd way to find: go to QXDM -> static message (there is a hot key for that, but i dont recollect), go to View->and check for static message. There you should be able to check the bands which mobile device supports.
and there are many other ways by which we can check the band settings.
