47. 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.


48. 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.


49. 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.


50. 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.


51. 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.


52. What are the different classes of GPRS?
What is the use of this GPRS classes?
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.


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


54. What are the common critical, blocker, major, minor bug founds 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.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.


55. What is Another name of PEER REVIEW MEETING?

56. Tell me How GPRS works?
GPRS work because of your mobile Sim, it receives the single from the nearby cellular tower and provide you the internet services


57. Where is the APN stored?
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).


58. How android application testing will be done?
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


59. How to test an application which is developed for multiple languages for e.g. a web application which is for English, Chinese, Japanese, french?
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.

The likelihood of an adverse event and the impact of the event determine the level of risk.


7. When is used Decision table testing?
Decision table testing is used for testing systems for which the specification takes the form of rules or cause-effect combinations. In a decision table the inputs are listed in a column, with the outputs in the same column but below the inputs. The remainder of the table explores combinations of inputs to define the outputs produced. Learn More About Decision Table Testing Technique in the Video Tutorial here

None, existing test cases can be used.


15. Rapid Application Development?
Rapid Application Development (RAD) is formally a parallel development of functions and subsequent integration. Components/functions are developed in parallel as if they were mini projects, the developments are time-boxed, delivered, and then assembled into a working prototype. This can very quickly give the customer something to see and use and to provide feedback regarding the delivery and their requirements. Rapid change and development of the product is possible using this methodology. However the product specification will need to be developed for the product at some point, and the project will need to be placed under more formal controls prior to going into production.


16. What is the difference between Testing Techniques and Testing Tools?
Testing technique: – Is a process for ensuring that some aspects of the application system or unit functions properly there may be few techniques but many tools. Testing Tools: – Is a vehicle for performing a test process. The tool is a resource to the tester, but itself is insufficient to conduct testing Learn More About Testing Tools here

19. What is component testing?
Component testing, also known as unit, module and program testing, searches for defects in, and verifies the functioning of software (e.g. modules, programs, objects, classes, etc.) that are separately testable. Component testing may be done in isolation from the rest of the system depending on the context of the development life cycle and the system. Most often stubs and drivers are used to replace the missing software and simulate the interface between the software components in a simple manner. A stub is called from the software component to be tested; a driver calls a component to be tested. Here is an awesome video on Unit Testing


20. What is functional system testing?
Testing the end to end functionality of the system as a whole is defined as a functional system testing.

When it is used?
Random testing often known as monkey testing. In such type of testing data is generated randomly often using a tool or automated mechanism. With this randomly generated input the system is tested and results are analysed accordingly. These testing are less reliable; hence it is normally used by the beginners and to see whether the system will hold up under adverse effects.

In contrast to informal reviews, formal reviews follow a formal process. A typical formal review process consists of six main steps: Planning Kick-off Preparation Review meeting Rework Follow-up.


31. What is the role of moderator in review process?
The moderator (or review leader) leads the review process. He or she determines, in co-operation with the author, the type of review, approach and the composition of the review team. The moderator performs the entry check and the follow-up on the rework, in order to control the quality of the input and output of the review process. The moderator also schedules the meeting, disseminates documents before the meeting, coaches other team members, paces the meeting, leads possible discussions and stores the data that is collected.

Structure-based testing techniques (which are also dynamic rather than static) use the internal structure of the software to derive test cases. They are commonly called 'white-box' or 'glass-box' techniques (implying you can see into the system) since they require knowledge of how the software is implemented, that is, how it works. For example, a structural technique may be concerned with exercising loops in the software. Different test cases may be derived to exercise the loop once, twice, and many times. This may be done regardless of the functionality of the software.


38. When "Regression Testing" should be performed?
After the software has changed or when the environment has changed Regression testing should be performed.


39. What is negative and positive testing?
A negative test is when you put in an invalid input and receives errors. While a positive testing, is when you put in a valid input and expect some action to be completed in accordance with the specification.

56. Which review is normally used to evaluate a product to determine its suitability for intended use and to identify discrepancies?
Technical Review.


57. Why we use decision tables?
The techniques of equivalence partitioning and boundary value analysis are often applied to specific situations or inputs. However, if different combinations of inputs result in different actions being taken, this can be more difficult to show using equivalence partitioning and boundary value analysis, which tend to be more focused on the user interface. The other two specification-based techniques, decision tables and state transition testing are more focused on business logic or business rules. A decision table is a good way to deal with combinations of things (e.g. inputs). This technique is sometimes also referred to as a 'cause-effect' table. The reason for this is that there is an associated logic diagramming technique called 'cause-effect graphing' which was sometimes used to help derive the decision table 58.

93. What is Coverage measurement?
It is a partial measure of test thoroughness.


94. What is Boundary value testing?
Test boundary conditions on, below and above the edges of input and output equivalence classes. For instance, let say a bank application where you can withdraw maximum Rs.20,000 and a minimum of Rs.100, so in boundary value testing we test only the exact boundaries, rather than hitting in the middle. That means we test above the maximum limit and below the minimum limit. 95. What is Fault Masking?
Error condition hiding another error condition.

Commercial off The Shelf.


97.The purpose of which is allow specific tests to be carried out on a system or network that resembles as closely as possible the environment where the item under test will be used upon release?
Test Environment


98. What can be thought of as being based on the project plan, but with greater amounts of detail?
Phase Test Plan 99. What is exploratory testing?
Exploratory testing is a hands-on approach in which testers are involved in minimum planning and maximum test execution. The planning involves the creation of a test charter, a short declaration of the scope of a short (1 to 2 hour) time-boxed test effort, the objectives and possible approaches to be used. The test design and test execution activities are performed in parallel typically without formally documenting the test conditions, test cases or test scripts. This does not mean that other, more formal testing techniques will not be used. For example, the tester may decide to use boundary value analysis but will think through and test the most important boundary values without necessarily writing them down. Some notes will be written during the exploratory-testing session, so that a report can be produced afterwards.

142. Explain what is N+1 testing?
The variation of regression testing is represented as N+1. In this technique the testing is performed in multiple cycles in which errors found in test cycle 'N' are resolved and re-tested in test cycle N+1. The cycle is repeated unless there are no errors found.


143. What is Fuzz testing and when it is used?
Fuzz testing is used to detect security loopholes and coding errors in software. In this technique random data is added to the system in attempt to crash the system. If vulnerability persists, a tool called fuzz tester is used to determine potential causes. This technique is more useful for bigger projects but only detects major fault.


144. Mention what are the main advantages of statement coverage metric of software testing?
The benefit of statement coverage metric is that a) It does not require processing source code and can be applied directly to object code b) Bugs are distributed evenly through code, due to which percentage of executable statements covered reflects the percentage of faults discovered

147. Mention what are the categories of defects?
Mainly there are three defect categories Wrong: When requirement is implemented incorrectly Missing: It is a variance from the specification, an indication that a specification was not implemented or a requirement of the customer is not met Extra: A requirement incorporated into the product that was not given by the end customer. It is considered as a defect because it is a variance from the existing requirements


148. Explain how does a test coverage tool works?
The code coverage testing tool runs parallel while performing testing on the actual product. The code coverage tool monitors the executed statements of the source code. When the final testing is done we get a complete report of the pending statements and also get the coverage percentage.

5) Mention what is the Android testing strategy?
The standard Android testing strategy must include the following test Unit Test Integration Test Operation Test System Test


6) Explain Android testing framework?
Android testing framework includes three segments Application Package: It is the target application that requires to be tested Instrumentation TestRunner: It is a test case runner that runs test cases on target application. It includes an SDK tools for building test and a tool that provides APIs for writing program that control an android device, for example, MonkeyRunner Test Package: It includes two classes, Test case classes, and Mock objects. Test case classes include test methods to perform on target application, while mock object includes mock data that will be used as sample input for test cases.


7) List out the best practices for Android Testing?
Developer should prepare the test cases at the same time when they are writing the code Together with source code all test cases should be stored Use continuous integration and execute tests every time the code is changed Avoid using rooted devices and emulators


8) Mention what are the common bugs found while mobile testing?
Critical: Your phone system crash when testing particular feature in your device Block: Unable to do anything though phone is on unless you reboot your device Major: Unable to perform a function of a particular feature Minor: Under minor bugs usually GUI bugs fall.


9) Explain what is Robo-electric testing framework?
Testing done on Android Testing Framework for emulators or device is difficult. Running and building test case sometimes takes lots of development effort. Robo-electric framework allows you to run Android test directly on JVM without the need of a device or an emulator.


10) Explain how A/B testing is done for ios app?
A/B testing for ios includes three steps Configure a test: It prepares two versions of your iOS app (A&B) and test metric Test: Tests two iOS versions above on devices simultaneously Analyze: It select and measure better version to release


11) While performing end to end mobile testing what are the major criteria, you have to take in consideration?
Installation Application launching without having network Uninstallation of app Orientation of app if it supports Testing application performance on a different kind of devices and network scenarios Testing the application response how it is responding


12) List out the features does monkey tool provides?
Monkey tools provide features like Basic configuration options Operational constraints Event types and frequencies Debugging options


13) Mention what should be the selecting criteria for Test Automation Tool for mobile Testing?
For mobile testing, the test automation tool should have following criteria Multi-platform support: Ensure that the tool does support your current and future target platform Script Usability: Object-based tools provides a high degree of the script usability Jailbreak Requirement: If the tool uses rooted devices, it may not support latest OS version and may be incompatible with MDM policies Source Code Changes: Sharing source code may not be possible always Lead time for New OS version: How soon tool can support new iOS/android/other OS version


14) When to choose automation testing and when manual testing?
Manual Testing If the application has new functionality If the application requires testing once or twice Automate Testing If the regression tests are repeated Testing app for complex scenarios
