Mobile Testing Interview Questions And Answers

1. Initially check the visibility of the device to others
while trying to search your device (Master)
2. Try to pair with device.
3. Change the visibility time (Ex: On, 1min, 3 min etc)
4. Rename the device (Slave)and try to pair with same
(Master)device and check for the name update in Master
5. Transfer of files from Master to slave and slave to master
6. Connect the call via BT headset
7. Try to pair with maximum devices allowed to pair
8. Try to share the files with all the maximum paired
devices at a time
9. Check that BT can be invoked from Multimedia applications
while trying to send the media/files
10. Try to send the contact via BT

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).

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

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.

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.

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.

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.

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 America
2100 (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.

There are three classes:
Class A
Class B
Class c


Class A
Can be connected to GPRS service and GSM service (voice,
SMS), using both at the same time. Such devices are known
to be available today.
Class B
Can be connected to GPRS service and GSM service (voice,
SMS), but using only one or the other at a given time.
During GSM service (voice call or SMS), GPRS service is
suspended, and then resumed automatically after the GSM
service (voice call or SMS) has concluded. Most GPRS mobile
devices are Class B.
Class C
Are connected to either GPRS service or GSM service (voice,
SMS). Must be switched manually between one or the other
service.

confermance testcases of a mobile can be refer spec 34.123,
for example For RLC/MAC 7.1. to 1.1.2.3 etc

CRITICAL BUG: This is nothing but a crash...suppose when u
r trying to play a song from media player of MIDI format,or
when a incoming call comes to your mobile when u r testing
a particular feature in your device it may crash.They r
many examples like this.

BLOCK: Unable to boot your device or unable to go back to
previous screen or unable to go to ur main menu when u r
testing particular feature.unable to invoke anything untill
and unless you reboot your device

Major: Unable to funtion or misfunctionality of a
particular feature

Minor: Usually GUI bugs comes under minor bugs. These bugs
wont affect functionality. Example overlapping of letters
in message compose screen.

The Peer review meeting is also called as " Technical
Review " meeting.

GPRS work because of your mobile Sim, it receives the single
from the nearby cellular tower and provide you the internet
services

APN's are used in establishing packet data connections, most
commonly to the Internet over 2G and 3G mobile networks.
APN's can be stored in contexts, which are identified by
number, and specify information on how to establish a data
session (packet orientation, c.f. circuit switched).

1. Write testcases as per the application functionality, as the same way you write for any of the software application.

2. Execute them and log a defect

3. Real time examples for mobile application that needs to verify are as below :
- When application is running on the device , you give interuption by call or sms or bluetooth
- When application is running check the CPU useage from the system settings menu
- If application is opening any URL from inside the application itself then check whether it is passing any confidential data
- Check application stability with wi-fi On/Off state
- Check application launch time after the interruption received

Language Testing is very important for any application. for
testing an application for different languages with out any
tools we can do testing in following way:
In IE ...
STEP 1 : Open an new IE browser
STEP 2 : Open Tools tab -> select Internet Options
STEP 3 : In General Tab -> select language (Available in
Appearance header)
STEP 4 : Click on Add and select a language and place it at
top navigating with move up button.

APPLY CHANGES.

IE will convert to language selected and we can test
according to requirements and specification.

the testing done with our knowledge is called intelligence
testing

Their are so many mobile core applications Few TCs for
feature interaction could be like
1.To able to receive calls while browsing in contacts.
2.To be able to attach photos in messages from gallery
3.To be able to receive calls while taking launching camera
4.To be able to receive Alarm notification in setting
applications
