Q. How can smoke testing be applied to mobile testing?
Smoke testing can be done on a Mobile once the latest build has been released to the testing team. Smoke test or build verification is nothing but just the basic functionality check for all the applications, test scope parameters that are involved in mobile application testing, testing very basic and important features of the mobile and also testing the showstopper issues at a higher priority level. 

Q. Is there any automation tool for mobile application testing ?
TestQuest is one of the best tools to automate mobile applications
Fitnesse tool can also be used to automate mobile applications.

What is your approach while Testing Mobile Applications?

The main aim of software testing is to find defect not to  prevent defect. So as per the testing concepts we try to  break the application.  But when u write test cases start with positive scenario,  cover the functionality as per the requirement  specification and then do negative scenario. Of course the  negative approach is as imporatnt as postive approach.

- What is test automation framework?

Planning or structre for smooth run running of apps

A test automation framework is a set of assumptions, concepts and tools that provide support for automated software testing. The main advantage of such a framework is the low cost for maintenance. If there is change to any test case then only the test case file needs to be updated and the Driver Script and Startup script will remain the same. Ideally, there is no need to update the scripts in case of changes to the application.

Choosing the right framework/scripting technique helps in maintaining lower costs. The costs associated with test scripting are due to development and maintenance efforts. The approach of scripting used during test automation has effect on costs.

What are different types of automation frameworks?

Data driven framework: http://www.onestopqa.com/data-driven-testing-framework.php

Keyword driven framework/table driven framework: http://www.onestopqa.com/the-keyword-driven.php

Hybrid test automation framework: http://www.onestopqa.com/hybrid-test-automation-framework.php

How android application testing will be done?

1.    Write test cases 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 interruption by call or sms or bluetooth
- When application is running check the CPU usage 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 

What is another name of PEER REVIEW MEETING?

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

 Explain what is actual mobile testing and in real-time how this testing happens?

Mobile Testing:

 Now-a-days, mobile market is growing with a gr8 speed. So many of the vendors is starting developing the applications which runs on a mobile device. The people 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 user 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, how the UI should be tested by the testers.

What are common critical, blocker, major, minor bugs found while testing a mobile?

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.
BLOCK:	Unable to boot your device/unable to go back to previous screen/unable to go to main menu when you are testing particular feature. Unable to invoke anything until and unless you reboot your device
MAJOR:	Unable to function or mis functionality of a particular feature
MINOR:	Usually GUI bugs come under minor bugs. These bugs won’t affect functionality. Example overlapping of letters
