- Base Filter Properties - The basic properties of a particular test object class whose values cannot be changed without changing the essence of the original object.
- Optional Filter Properties - Other properties also assist in identifying the objects of a particular class whose properties are unlikely to change often but can be ignored if they are no longer applicable.

Sometimes, QTP is unable to find any object that matches the recognized object description or it may find more than one object that fits the description, then QTP ignores the recognized description and uses the Smart Identification mechanism to recognize the object.
QTP's Smart Identification uses two types of properties:
Step 1 : Navigate to "Tools" -> "Object Identification". Object Identification Dialog Opens.
Step 2 : Choose the Environment, Object Class and Turn ON "Enable Smart Identification" as shown below:
Step 3 : Click Configure and choosing the base and Optional Filter Properties.
Step 3 : Add Properties in Base Properties apart from the Default one and also add/remove Optional Filter Properties. Please Note that Same properties cannot be part of both Mandatory and Assistive Properties and click "OK".
Step 4 : Verifying if the Smart Identification is Enabled after Adding object of that type in the Object Repository. Smart Identification is Set to TRUE. We can also make it False in case we dont want to enable Smart Identification.
Step 5 : We can even disable a test Level by applying at test script level under "Settings" of "File" Menu as shown below:
Step 6 : If the Smart Identification is disabled as per Step# 6 then it wont apply smart identification for any object during script execution.
Step 7 : In case objects are added with Smart Identification as Off, QTP won't use Smart Identification for recognizing in future, even though we have enabled it afterwords.

What is Synchronization?
Synchronization point is the time interface between Tool and Application under test. Synchronization point is a feature to specify delay time between one step and another of the test script.
For Example, clicking on a link may load the page is 1 second, sometimes 5 seconds or even it might take 10 seconds to load it completely. It depends on various factors such as the application server response time, network bandwidth , client system capabilities etc.
If the time is varying then the script will fail unless the tester handles these time differences intelligently.
Ways to Insert Sync Point:
- WaitProperty
- Exist
- Wait
- Sync(only for web based apps)
- Inserting QTP Inbuilt Synchronization points.
Let us say we need to insert a sync point beween clicking on "numbers" link and clicking on "simple Interest" calculator of in "http://easycalculation.com/". We will now take a look at all the 5 ways to insert sync point for the above scenario.
METHOD 1: WAITPROPERTY
WaitProperty is a method that takes the property name, Value and Timeout value as input to perform the sync. It is a dynamic wait and hence this option is encouraged.
' Method 1 - WaitProperty with 25 seconds
Dim obj
Set obj = Browser("Math Calculator").Page("Math Calculator")
obj.Link("Numbers").Click
obj.Link("Simple Interest").WaitProperty "text", "Simple Interest",25000
obj.Link("Simple Interest").Click
METHOD 2: EXIST
Exist is a method that takes the Timeout value as input to perform the sync. Again it is a dynamic wait and hence this option is encouraged.
' Method 2 : Exist Timeout - 30 Seconds
Dim obj
Set obj = Browser("Math Calculator").Page("Math Calculator")
obj.Link("Numbers").Click
If obj.Link("Simple Interest").Exist(30) Then
obj.Link("Simple Interest").Click
Else
Print "Link NOT Available"
End IF
METHOD 3: WAIT
Wait is a hardcoded sync point which waits independent of the event happened or NOT. Hence usage of Wait is discouraged and can be used for shorter wait time such as 1 or 2 seconds.
' Method 3 : Wait Timeout - 30 Seconds
Dim obj
Set obj = Browser("Math Calculator").Page("Math Calculator")
obj.Link("Numbers").Click
wait(30)
Browser("Math Calculator").Page("Math Calculator").Link("Simple Interest").Click
METHOD 4: SYNC METHOD
Sync Method can be used only for web applications where there is always a lag between page loads.
' Method 4 :
Dim obj
Set obj = Browser("Math Calculator").Page("Math Calculator")
obj.Link("Numbers").Click
Browser("Math Calculator").Sync
Browser("Math Calculator").Page("Math Calculator").Link("Simple Interest").Click
METHOD 5 : INSERTING QTP INBUILT SYNCHRONIZATION POINTS:
Step 1 : Get into Recording Mode. This Option Would be Disabled if the user is NOT in Recording Mode.
Step 2 : Goto "Design" -> "Synchronization Point" .
Step 3 : We need to Select the object which we want to be the Sync Point. After Selecting the object, object window opens as shown below:
Step 4 : Click Ok, the "Add Synchronization Window" Opens up. Select the Property, Value and Time out value and click ok as shown below:
Step 5 : The Script would be generated as shown below which is the same as that of the WaitProperty(Method 1) that we had already discussed:
Browser("Math Calculator").Page("Math Calculator").Link("Numbers").Click Browser("Math Calculator").Page("Math Calculator").Link("Simple Interest").WaitProperty "text", "Simple Interest", 10000
Default Synchronization:
When user hasn't used any of the above sync methods, still QTP has inbuild Object synchronization timeout which can be adjusted by the user.
Navigate to "File" >> "Settings" >> Run Tab >> Object Synchronization Time out as shown below.

What are CheckPoints?
Checkpoints, as the name says it all, it refers to a validation point that compares the current value for specified properties or current state of an object with the expected value which can be inserted at any point of time in the script.
Types:
Type | Description |
---|---|
Standard Checkpoint | Verifies the property values of an object in application under test and supported by all add-in environments. |
Bitmap Checkpoint | Verifies an area of your application as a bitmap |
File Content Checkpoint | Verifies the text in a dynamically generated or accessed file such as .txt,.pdf |
Table Checkpoint | Verifies the information within a table. Not all environments are supported. |
Text Checkpoint | Verify if the text that is displayed within a defined area in a Windows-based application, according to specified criteria. |
Text Area Checkpoint | Verifies if the text string is displayed within a defined area in a Windows-based application, according to specified criteria. |
Accessibility Checkpoint | Verifies the page and reports the areas of the Web site that may not conform to the World Wide Web Consortium (W3C) Web Content Accessibility Guidelines |
Page Checkpoint | Verifies the characteristics of a Web page. It can also check for broken links. |
Database Checkpoint | Verifies the contents of a database accessed by the application under test. |
XML Checkpoint | Verifies the content of the .xml documents or .xml documents in Web pages and frames. |
Inserting CheckPoint
When the user wants to insert a checkpoint, one has to ensure that most of the checkpoints are supported during the recording sessions only. Once the user stops recording, checkpoints are NOT enabled.
Below is the checkpoint menu, when the user is NOT in the recording mode.
Below is the checkpoint menu, when the user is in the recording mode.
Example:
The checkpoints are added for the application under test - "http://easycalculation.com/"
' 1. Inserted Standard Checkpoint Status = Browser("Math Calculator").Page("Math Calculator").Link("Numbers").Check CheckPoint("Numbers") If Status Then print "Checkpoint Passed" Else Print "Checkpoint Failed" End if ' 2. Inserted BitMap Checkpoint imgchkpoint = Browser("Math Calculator").Page("Math Calculator").Image("French").Check CheckPoint("French") If imgchkpoint Then print "Checkpoint Passed" Else Print "Checkpoint Failed" End if
Viewing Checkpoint Properties
After Inserting, incase a tester want to change the values, we can do so by performing right click on the keyword 'checkpoint' of the script and navigating to "Checkpoint Properties" as shown below:
You can locate the same checkpoints in object repository as well as shown below. It exactly shows what type of checkpoint and what are the expected values, time out values.

Datatables:
A DataTable, similar to Microsoft Excel helps testers to create data driven test cases that can be used to run an Action multiple times. There are two types of Datatables.
- Local Data Table - Each action has its own private data table also known as local data table which is can also be accessed across actions.
- Global Data Table - Each test has one global data sheet that is accessible across actions.
The Data sheet can be accessed from the "Data" Tab of QTP as shown below:
To execute a test case for some specified number of iterations,one can set the iterations of global data table in the Test Settings dialog, that can be accessed using File -> Settings -> Run(Tab) as shown below:
Example:
For Instance, if user wants to parameterize "compound Interest" of "http://zubaerkhan.com/" that can be accessed using "http://zubaerkhan.com/compound-interest.php". The Parameters can be created as shown below. Most of the functionalities of Excel can be used in Data table as well.
Data Table Operations:
There are three types of objects to access Data Table. Data Table Operations can be well understood by traversing through the below link:
Object Type | Description |
---|---|
Data Table Methods | Gives Detailed information about the data table methods. |
DTParameter Object Methods | Gives Detailed information about the DTParameter methods. |
DTSheet Object Methods | Gives Detailed information about the DTSheet methods. |

Actions:
Actions helps testers to divide scripts into groups of QTP statements called actions. Actions are similar to functions in VBScript, however there are few differences. By Default QTP creates a test with 1 action.
Actions Functions
Actions are inbuild feature of QTP. VBScript Functions are supported by both VBScript and QTP.
Actions parameters are passed byvalue only. Function parameters are passed either by byvalue or byref.
Actions have extension .mts Functions are saved as .vbs or .qfl
Actions may or maynot be reusable. Functions are always reusable.
The properties of the action can be accessed by Right Clicking on the Script Editor Window and Selecting "Properties".
Action properties contains following information
Action Name
Location
Reusable Flag
Input Parameters
Output Parameters
Types of Actions:
There are three types of actions:
Non-reusable action - An action that can be called only in that specific test in which it has been designed and can be called only once
Reusable action - An action that can be called multiple times any test in which it resides and can also be used by any other tests
External Reusable action - It is a reusable action stored in another test. External actions are read-only in the calling test, but it can be used locally with the editable copy of the Data Table information for the external action

Significance of Record and Playback:
It is used as the preliminary investigation method to verify if UFT can support the technology/application.
Used to create a test a basic functionality of an application or feature that does not require long-term maintenance.
It can be used for recording both mouse movements and keyboard inputs.
Modes of Recording:
Normal Recording: This is the default Recording mode that records the objects and the operations performed on the application under test.
Analog Recording: This records not only the keyboard actions but also the mouse movements relative to the screen or the application window.
Low-Level Recording: This records the exact co-ordinates of the objects independent of the fact whether UFT recognizes the object or NOT. It just records the co-ordinates, hence does NOT record mouse movements.
Insight Recording: UFT records operation based on its appearance and NOT based on its native properties.
How to Choose Recording Modes:
Upon clicking on Recording button, user can choose the recording mode from the recording pane that appears on the screen once recording starts. The selection can be made from any the ones that has been discussed above.
The Below Scenario is recorded in all the modes and see how the same action has been recorded under various circumstances.
Launch IE - http://zubaerkhan.com/
Click "Numbers" under "Algebra"
Click "Square Root" link
Enter a value to calculate the square root. Let us say 10
Hit Calculate

Q1. What is Requirement Traceability Matrix?
The Requirements Traceability Matrix (RTM) is a tool to make sure that project requirement remain same throughout the whole development process. RTM is used in the development process because of following reasons:
• To determine whether the developed project is meet the requirements of the user.
• To determine all the requirements given by the user
• To make sure the application requirement can be fulfilled in the verification process.
• To determine all the requirements given by the user
• To make sure the application requirement can be fulfilled in the verification process.
Q2. What is difference between Pilot and Beta testing?
The differences between these two are listed below:
• A beta test when the product is about to release to the end user whereas pilot testing take place in the earlier phase of the development cycle.
• In beta testing application is given to a few user to make sure that application meet the user requirement and does not contain any showstopper whereas in case of pilot testing team member give their feedback to improve the quality of the application.
• In beta testing application is given to a few user to make sure that application meet the user requirement and does not contain any showstopper whereas in case of pilot testing team member give their feedback to improve the quality of the application.
Q3. Describe how to perform Risk analysis during software testing?
Risk analysis is the process of identifying risk in the application and prioritizing them to test. Following are some of the risks:
1. New Hardware.
2. New Technology.
3. New Automation Tool.
4. Sequence of code delivery.
5. Availability of application test resources.
2. New Technology.
3. New Automation Tool.
4. Sequence of code delivery.
5. Availability of application test resources.
We prioritize them into three categories these are:
• High magnitude: Impact of the bug on the other functionality of the application.
• Medium: it can be tolerable in the application but not desirable.
• Low: it can be tolerable. This type of risk has no impact on the company business.
• Medium: it can be tolerable in the application but not desirable.
• Low: it can be tolerable. This type of risk has no impact on the company business.
Q4. What is Silk Test?
Silk Test is a tool developed for performing the regression and functionality testing of the application. Silk Test a tool is used when we are testing the applications which are based on Window, Java, web or traditional client/server. Silk Test help in preparing the test plan and management of those test plans, to provide the direct accessing of the database and validation of the field.
Q5. What is difference between Master Test Plan and Test Plan.
The differences between Master Plan and Test Plan are given below:
• Master Test Plan contains all the testing and risk involved area of the application where as Test case document contains test cases.
• Master Test plan contain all the details of each and every individual tests to be run during the overall development of application whereas test plan describe the scope, approach, resources and schedule of performing test.
• Master Test plan contain the description of every tests that is going to be performed on the application where as test plan only contain the description of few test cases. during the testing cycle like Unit test, System test, beta test etc
• Master Test Plan is created for all large projects but when it is created for the small project then we called it as test plan.
• Master Test plan contain all the details of each and every individual tests to be run during the overall development of application whereas test plan describe the scope, approach, resources and schedule of performing test.
• Master Test plan contain the description of every tests that is going to be performed on the application where as test plan only contain the description of few test cases. during the testing cycle like Unit test, System test, beta test etc
• Master Test Plan is created for all large projects but when it is created for the small project then we called it as test plan.
Q6. How to deal with not reproducible bug?
Ans. A bug cannot be reproduced for following reasons:
1. Low memory.
2. Addressing to non available memory location.
3. Things happening in a particular sequence.
2. Addressing to non available memory location.
3. Things happening in a particular sequence.
Tester can do following things to deal with not reproducible bug:
• Includes steps that are close to the error statement.
• Evaluate the test environment.
• Examine and evaluate test execution results.
• Resources & Time Constraints must be kept in point.
• Evaluate the test environment.
• Examine and evaluate test execution results.
• Resources & Time Constraints must be kept in point.
Q7.What is the difference between coupling and cohesion?
The difference between coupling and cohesion is discussed below:
• Cohesion is the degree which is measure dependency of the software component that combines related functionality into a single unit whereas coupling means that binding the related functionality into different unit.
• Cohesion deals with the functionality that related different process within the single module where as coupling deals with how much one module is dependent on the other modules within the application.
• It is good to increase the cohesion between the software whereas increasing coupling is avoided.
• Cohesion deals with the functionality that related different process within the single module where as coupling deals with how much one module is dependent on the other modules within the application.
• It is good to increase the cohesion between the software whereas increasing coupling is avoided.
Q8. What is the role of QA in a project development?
The role of Quality Assurance is discussed below:
• QA team is responsible for monitoring the process to be carried out for development.
• Responsibilities of QA team are planning testing execution process.
• QA Lead creates the time tables and agrees on a Quality Assurance plan for the product.
• QA team communicated QA process to the team members.
• QA team ensures traceability of test cases to requirements.

Q11. What is difference between QA, QC and Software Testing?
Quality Assurance (QA): QA refers to the planned and systematic way of monitoring the quality of process which is followed to produce a quality product. QA tracks the outcomes and adjusts the process to meet the expectation.
Quality Control (QC): Concern with the quality of the product. QC finds the defects and suggests improvements. The process set by QA is implemented by QC. The QC is the responsibility of the tester.
Software Testing: is the process of ensuring that product which is developed by the developer meets the user requirement. The motive to perform testing is to find the bugs and make sure that they get fixed.
Q12. What is concurrent user hits in load testing?
When the multiple users, without any time difference, hits on a same event of the application under the load test is called a concurrent user hit. The concurrency point is added so that multiple Virtual User can work on a single event of the application. By adding concurrency point, the virtual users will wait for the other Virtual users which are running the scripts, if they reach early. When all the users reached to the concurrency point, only then they start hitting the requests.
Q13. What is difference between Front End Testing and Back End testing?
The differences between front and back end testing are:
• Front End Testing is performed on the Graphical User Interface (GUI).whereas Back End Testing involves databases testing.
• Front end consist of web site look where user can interact whereas in case of back end it is the database which is required to store the data.
• When ender user enters data in GUI of the front end application, then this entered data is stored in the database. To save this data into the database we write SQL queries.
• Front end consist of web site look where user can interact whereas in case of back end it is the database which is required to store the data.
• When ender user enters data in GUI of the front end application, then this entered data is stored in the database. To save this data into the database we write SQL queries.
Q14. What is Automated Testing?
The process of performing testing automatically which reduces the human intervention this is automation testing. The automation testing is carried out with the help of the some automation tool like QTP, Selenium, WinRunner etc. In automation testing we use a tool that runs the test script to test the application; this test script can be generated manually or automatically. When testing is completed then tools automatically generate the test report and report.
Q15. What is Testware?
The testware is:
• The subset of software which helps in performing the testing of application.
• Testware are required to plan, design, and execute tests. It contains documents, scripts, inputs, expected results, set-up and additional software or utilities used in testing.
• Testware is term given to combination of all utilities and application software that required for testing a software package.
• Testware are required to plan, design, and execute tests. It contains documents, scripts, inputs, expected results, set-up and additional software or utilities used in testing.
• Testware is term given to combination of all utilities and application software that required for testing a software package.
Testware is special because it has:
1. Different purpose
2. Different metrics for quality and
3. Different users
2. Different metrics for quality and
3. Different users
Q16.What is Exhaustive Testing?
Exhaustive Testing, as the name suggests is very exhaustive. Exhaustive testing means to test every component in the application with every possible number of inputs. According to Principles of testing Exhaustive Testing is Impossible because exhaustive testing requires more time and effort to test the application for all possible number of inputs. This may lead to high cost and delay in the release of the application.
Q17. What is Gray Box Testing?
Grey box testing is the hybrid of black box and white box testing. In gray box testing, test engineer has the knowledge of coding section of the component and designs test cases or test data based on system knowledge. In this tester has knowledge of code, but this is less than the knowledge of white box testing. Based on this knowledge the test cases are designed and the software application under test treats as a black box & tester test the application from outside.
Q18. What is Integration Testing?
Integration testing is black box testing. Integration testing focuses on the interfaces between units, to ensure that units work together to complete a specify task. The purpose of integration testing is to confirm that different components of the application interact with each other. Test cases are developed with the purpose of exercising the interfaces between the components. Integration testing is considered complete, when actual results and expected results are same. Integration testing is done after unit testing. There are mainly three approaches to do integration testing:
• Top-down Approach tests the components by integrating from top to bottom.
• Bottom-up approach It takes place from the bottom of the control flow to the higher level components
• Big bang approach In this are different module are joined together to form a complete system and then testing is performed on it.
• Bottom-up approach It takes place from the bottom of the control flow to the higher level components
• Big bang approach In this are different module are joined together to form a complete system and then testing is performed on it.
Q19. What is Scalability Testing?
Scalability testing is testing performed in order to enhanced and improve the functional and performance capabilities of the application. So that, application can meets requirements of the end users. The scalability measurements is done by doing the evaluating the application performance in load and stress conditions. Now depending upon this evaluation we improve and enhanced the capabilities of the application.
Q20. What is Software Requirements Specification?
• A software requirements specification is a document which acts as a contract between the customer and the supplier.
• This SRS contain all the requirement of the end user regarding that application. SRS can be used as a communication medium between the customer and the supplier.
• The developer and tester prepare and examine the application based on the requirements written in the SRS document.
• The SRS documented is prepared by the Business Analyst by taking all the requirements for the customer.

Q21. What is Storage Testing?
In Storage Testing we test those functionalities of the application which is responsible for storing the data into database. The data entered by the end user in GUI or front end, is the same data which is stored in the database. The storage testing determines that the data taken from the front end of the application is stored in correct place and in correct manner in the database.
Q22. What is Stress Testing?
Stress testing tests the software with a motive to check that the application do not crashes if we increase the stress on the application by increasing the large number of user working on the application. We can also apply the stress on the application firing the lots of process which cannot be handled by the application. We perform the stress testing on the application evaluate the application capabilities at or beyond the limits of its specified requirements to determine. Generally, this is a type of performance testing performed in a very high level of load and stress condition.
Q23. What is Test Harness?
A test harness is a collection of software and test data required to test the application by running it in different testing condition like stress, load, data- driven, and monitoring its behavior and outputs. Test Harness contains two main parts:
• Test execution engine
• Test script repository
• Test script repository
Automation testing is the use of a tool to control the execution of tests and compare the actual results with the expected results. It also involves the setting up of test pre-conditions.
Q24. Can you define test driver and test stub?
• The Stub is called from the software component to be tested. It is used in top down approach.
• The driver calls a component to be tested. It is used in bottom up approach.
• Both test stub and test driver are dummy software components.
• The driver calls a component to be tested. It is used in bottom up approach.
• Both test stub and test driver are dummy software components.
We need test stub and test driver because of following reason:
• Suppose we want to test the interface between modules A and B and we have developed only module A. So we cannot test module A but if a dummy module is prepare, using that we can test module A.
• Now module B cannot send or receive data from module A directly so, in these cases we have to transfer data from one module to another module by some external features. This external feature used is called Driver.
• Now module B cannot send or receive data from module A directly so, in these cases we have to transfer data from one module to another module by some external features. This external feature used is called Driver.
Q25.What is good design?
Design refers to functional design or internal design. Good internal design is indicated by software code whose overall structure is clear, understandable, easily modifiable, and maintainable; is robust with sufficient error-handling and status logging capability, and works correctly when implemented. Good functional design is indicated by an application whose functionality can be traced back to customer and end-user requirements.
Q26. What makes a good QA or Test manager?
A good QA or Test manager should have following characteristics:
• Knowledge about Software development process
• Improve the teamwork to increase productivity
• Improve cooperation between software, test, and QA engineers
• To improvements the QA processes.
• Communication skills.
• able to conduct meetings and keep them focused
• Improve the teamwork to increase productivity
• Improve cooperation between software, test, and QA engineers
• To improvements the QA processes.
• Communication skills.
• able to conduct meetings and keep them focused
Q27. What is Manual scripted Testing and Manual Support testing?
Manual Scripted Testing: Testing method in which the test cases are designed and reviewed by the team before executing it. It is done by manual testing teams.
Manual-Support Testing: Testing technique that involves testing of all the functions performed by the people while preparing the data and using these data from automated system. it is conducted by testing teams
Manual-Support Testing: Testing technique that involves testing of all the functions performed by the people while preparing the data and using these data from automated system. it is conducted by testing teams
Q28. What is Fuzz testing, backward compatibility testing and assertion testing?
Fuzz Testing: testing application by entering invalid, unexpected, or random data to the application this testing is performed to ensure that application is not crashing when entering incorrect and unformatted data.
Backward Compatibility Testing: Testing method which examines performance of latest software with older versions of the test environment.
Assertion Testing: Type of testing consisting in verifying if the conditions confirm the product requirements.
Assertion Testing: Type of testing consisting in verifying if the conditions confirm the product requirements.
Q29. How does a client or server environment affect testing?
There are lots of environmental factors that affect the testing like speed of data transfer data transfer, hardware, and server etc while working with client or server technologies, testing will be extensive. When we have time limit, we do the integration testing. In most of the cases we prefer the load, stress and performance testing for examine the capabilities of the application for the client or server environment.
Q30. What are the categories of defects?
There are three main categories of defects:
• Wrong: The requirements are implemented incorrectly in the application.
• Missing: When requirement given by the customer and application is unable to meet those application.
• Extra: A requirement incorporated into the product that was not given by the end customer. This is always a variance from the specification, but may be an attribute desired by the user of the product.
• Missing: When requirement given by the customer and application is unable to meet those application.
• Extra: A requirement incorporated into the product that was not given by the end customer. This is always a variance from the specification, but may be an attribute desired by the user of the product.
