Ques: 3 How to insert a check point to a image to check enable property in QTP?

Ans:
AS we are saying that the all images are as push button than we can check the property enabled or disabled. If we are not able to find that property than go to object repository for that objecct and click on add remove to add the available properties to that object. Let me know if that works. And if we take it as image than we need to check visible or invisible property tht also might help you are there are no enable or disable properties for the image object.

Ques: 7 How to choose which defect to remove in 1000000 defects?

Ans:

How to choose which defect to remove in 1000000 defects? (because It will take too much resources in order to remove them all.)

Software QA/Testing Technical FAQs

(Continued from previous question...)

How to choose which defect to remove in 1000000 defects? (because It will take too much resources in order to remove them all.)

Answe1:
Are you the programmer who has to fix them, the project manager who has to supervise the programmers, the change control team that decides which areas are too high risk to impact, the stakeholder-user whose organization pays for the damage caused by the defects or the tester?
The tester does not choose which defects to fix.
The tester helps ensure that the people who do choose, make a well-informed choice.
Testers should provide data to indicate the *severity* of bugs, but the project manager or the development team do the prioritization.
When I say "indicate the severity", I don't just mean writing S3 on a piece of paper. Test groups often do follow-up tests to assess how serious a failure is and how broad the range of failure-triggering conditions.
Priority depends on a wide range of factors, including code-change risk, difficulty/time to complete the change, which stakeholders are affected by the bug, the other commitments being handled by the person most knowledgeable about fixing a certain bug, etc. Many of these factors are not within the knowledge of most test groups.
we surely can prioritize them once detected. In our org we assign severity level to the defects depending upon their influence on other parts of products. If a defect doesnt allow you to go ahead and test test the product, it is critical one so it has to be fixed ASAP. We have 5 levels as
-critical
-High
-Medium
-Low
-Cosmetic

Ques: 8 Is regression testing performed manually?

Ans:
If the initial testing approach was manual testing, then the regression testing is usually performed manually. Conversely, if the initial testing approach was automated testing, then the regression testing is usually performed by automated testing.

Ques: 9 How to find all the Bugs during first round of Testing?

Ans:
We understand the problems we are facing. I was involved with a web-based HR system that was encountering the same problems. What I ended up doing was going back over a few release cycles and analyzing the types of defects found and when (in the release cycle including the various testing cycles) they were found. I started to notice a distinct trend in certain areas.
For each defect type, I started looking into the possibility if it could have been caught in the prior phase (lots of things were being found in the Systems test phase that should have been caught earlier). If so, why wasn't it caught? Could it have been caught even earlier (say via a peer review)? If so, why not? This led me to start examining the various processes and found a definite problem with peer reviews (not very thorough IF they were even being done) and with the testing process (not rigorous enough). We worked with the customer and folks doing the testing to start educating them and improving the processes. The result was the number of defects found in the latter test stages (System test for example) were cut by over half! It was getting harder to find problems with the product as they were discovering them earlier in the process -- saving time & money!

Ques: 10 How to remove a description from the collection ?

Ans:
obj_ChkDesc.remove html tag would delete the html tag property from the collection.

Ques: 11 How do I check if property exists or not in the collection?

Ans:
The answer is that it's not possible. Because whenever we try to access a property which is not defined its automatically added to the collection. The only way to determine is to check its value that is use a if statement if obj_ChkDesc(html tag).value = empty then.

Ques: 12 What is the difference between version and release?

Ans:
Both version and release indicate particular points in the software development life cycle, or in the life cycle of a document. Both terms, version and release, are similar, i.e. pretty much the same thing, but there are minor differences between them.
1: Version means a variation of an earlier or original type. For example, you might say, "I've downloaded the latest version of XYZ software from the Internet. The version number of this software is _____"
2: Release is the act or instance of issuing something for publication, use, or distribution. Release means something thus released. For example, "Microsoft has just released their brand new gaming software known as _______"

Ques: 13 Why Testing CANNOT Ensure Quality

Ans:
Testing in itself cannot ensure the quality of software. All testing can do is give you a certain level of assurance (confidence) in the software. On its own, the only thing that testing proves is that under specific controlled conditions, the software functioned as expected by the test cases executed.

Ques: 14 How to write Test cases for Login screen?

Ans:
The format for all test cases could be something like this
> test cases for GUI
> +ve test cases for login.
> -ve test cases for login.
in the -ve scenario : we should include boundary analysis to create test cases ,Value Analysis. Equivalence Classes,Positive and Negative test cases) plus cross-site scripting and SQL injection. SQL injection is especially high-risk for login pages.

Ques: 15 What is the checklist for credit card testing?

Ans:
In credit card testing the following validations are considered
> Testing the 4-DBC (Digit batch code) for its uniqueness (present on right corner of credit card)
> The message formats in which the data is sent
> LUHN testing
> Network response
> Terminal validations

Ques: 16 How to browse through all the properties of a properties collection?

Ans:
Two ways are there : 
	1st :
		For each desc in obj_ChkDesc
			Name=desc.Name
			Value=desc.Value
			RE = desc.regularexpression
		Next
	2nd :
		For i=0 to obj_ChkDesc.count - 1
			Name= obj_ChkDesc(i).Name
			Value= obj_ChkDesc(i).Value
			RE = obj_ChkDesc(i).regularexpression
		Next

Ques: 17 What is software testing methodology?

Ans:
One software testing methodology is the use a three step process of : 
> Creating a test strategy;
> Creating a test plan/design; and
> Executing tests. 
          This methodology can be used and molded to our organization's needs. Rob Davis believes that using this methodology is important in the development and ongoing maintenance of his clients' applications.

Ques: 19 What black box testing types can you tell me about?

Ans:
Black box testing is functional testing, not based on any knowledge of internal software design or code. Black box testing is based on requirements and functionality. 
> Functional testing is also a black-box type of testing geared to functional requirements of an application.
> System testing is also a black box type of testing. 
> Acceptance testing is also a black box type of testing. 
> Functional testing is also a black box type of testing.
> Closed box testing is also a black box type of testing. 
> Integration testing is also a black box type of testing.

Ques: 20 Why do we perform data integrity testing?

Ans:
Because we want to verify the completeness, soundness, and wholeness of the stored data. Testing should be performed on a regular basis, because important data could, can, and will change over time.
