Software Testing Interview Questions Part 5 »

46. High severity, low priority bug?

A: — A page is rarely accessed, or some activity is performed rarely but that thing outputs some important Data incorrectly, or corrupts the data, this will be a bug of H severity L priority

47. If project wants to release in 3months what type of Risk analysis u do in Test plan?

A:– Use risk analysis to determine where testing should be focused. Since it’s rarely possible to test every possible aspect of an application, every possible combination of events, every dependency, or everything that could go wrong, risk analysis is appropriate to most software development projects. This requires judgment skills, common sense, and experience. (If warranted, formal methods are also available.) Considerations can include:

• Which functionality is most important to the project’s intended purpose?
• Which functionality is most visible to the user?
• Which functionality has the largest safety impact?
• Which functionality has the largest financial impact on users?
• Which aspects of the application are most important to the customer?
• Which aspects of the application can be tested early in the development cycle?
• Which parts of the code are most complex, and thus most subject to errors?
• Which parts of the application were developed in rush or panic mode?
• Which aspects of similar/related previous projects caused problems?
• Which aspects of similar/related previous projects had large maintenance expenses?
• Which parts of the requirements and design are unclear or poorly thought out?
• What do the developers think are the highest-risk aspects of the application?
• What kinds of problems would cause the worst publicity?
• What kinds of problems would cause the most customer service complaints?
• What kinds of tests could easily cover multiple functionalities?
• Which tests will have the best high-risk-coverage to time-required ratio

48. Test cases for IE 6.0 ?

A:– Test cases for IE 6.0 i.e Internet Explorer 6.0:—
1)First I go for the Installation side, means that –
+ is it working with all versions of Windows ,Netscape or other softwares in other words we can say that IE must check with all hardware and software parts.
2) Secondly go for the Text Part means that all the Text part appears in frequent and smooth manner.
3) Thirdly go for the Images Part means that all the Images appears in frequent and smooth manner.
4) URL must run in a better way.
5) Suppose Some other language used on it then URL take the Other Characters, Other than Normal Characters.
6)Is it working with Cookies frequently or not.
7) Is it Concerning with different script like JScript and VBScript.
8) HTML Code work on that or not.
9) Troubleshooting works or not.
10) All the Tool bars are work with it or not.
11) If Page has Some Links, than how much is the Max and Min Limit for that.
12) Test for Installing Internet Explorer 6 with Norton Protected Recycle Bin enabled .
13) Is it working with the Uninstallation Process.
14) Last but not the least test for the Security System for the IE 6.0

49. Where you involve in testing life cycle ,what type of test you perform ?

A:– Generally test engineers involved from entire test life cycle i.e, test plan, test case preparation, execution, reporting. Generally system testing, regression testing, adhoc testing
etc.

50. what is Testing environment in your company ,means hwo testing process start ?

A:– testing process is going as follows
quality assurance unit
quality assurance manager
testlead
test engineer

51. who prepares the use cases?

A:– In Any company except the small company Business analyst prepares the use cases
But in small company Business analyst prepares along with team lead

52. What methodologies have you used to develop test cases?

A:– generally test engineers uses 4 types of methodologies
1. Boundary value analysis
2.Equivalence partition
3.Error guessing
4.cause effect graphing

53. Why we call it as a regression test nor retest?

A:– If we test whether defect is closed or not i.e Retesting But here we are checking the impact also regression means repeated times

54. Is automated testing better than manual testing. If so, why?

A:– Automated testing and manual testing have advantages as well as disadvantages
Advantages: It increase the efficiency of testing process speed in process
reliable
Flexible
disadvantage’s
Tools should have compatibility with our development or deployment tools needs lot of time initially If the requirements are changing continuously Automation is not suitable
Manual: If the requirements are changing continuously Manual is suitable Once the build is stable with manual testing then only we go 4 automation
Disadvantages:
It needs lot of time
We can not do some type of testing manually
E.g Performances

55. what is the exact difference between a product and a project.give an example ?

A:– Project Developed for particular client requirements are defined by client Product developed for market Requirements are defined by company itself by conducting market survey
Example
Project: the shirt which we are interested stitching with tailor as per our specifications is project
Product: Example is “Ready made Shirt” where the particular company will imagine particular measurements they made the product
Mainframes is a product
Product has many mo of versions
but project has fewer versions i.e depends upon change request and enhancements

56. Define Brain Stromming and Cause Effect Graphing? With Eg?

A:– BS:
A learning technique involving open group discussion intended to expand the range of available ideas
OR
A meeting to generate creative ideas. At PEPSI Advertising, daily, weekly and bi-monthly brainstorming sessions are held by various work groups within the firm. Our monthly I-
Power brainstorming meeting is attended by the entire agency staff.
OR
Brainstorming is a highly structured process to help generate ideas. It is based on the principle that you cannot generate and evaluate ideas at the same time. To use brainstorming, you must first gain agreement from the group to try brainstorming for a fixed interval (eg six minutes).

CEG :
A testing technique that aids in selecting, in a systematic way, a high-yield set of test cases that logically relates causes to effects to produce test cases. It has a beneficial side effect in pointing out incompleteness and ambiguities in specifications.

57. Actually by using severity u should know which one u need to solve so what is the need of priority?

A:– I guess severity reflects the seriousness of the bug where as priority refers to which bug should rectify first. of course if the severity is high the same case is with priority in normal.

severity decided by the tester where as priority decided by developers. which one need to solve first knows through priority not with severity. how serious of the bug knows through
severity.

severity is nothing impact of that bug on the application. Priority is nothing but importance to resolve the bug yeah of course by looking severity we can judge but sometimes high severity bug doesn’t have high priority At the same time High priority bug don’t have high severity
So we need both severity and priority

58. What do u do if the bug that u found is not accepted by the developer and he is saying its not reproducible. Note:The developer is in the on site location ?

A:– once again we will check that condition with all reasons. then we will attach screen shots with strong reasons. then we will explain to the project manager and also explain to the client when they contact us

Sometimes bug is not reproducible it is because of different environment suppose development team using other environment and you are using different environment at this situation there is chance of bug not reproducing. At this situation please check the environment in the base line documents that is functional documents if the environment which we r using is correct we will raise it as defect We will take screen shots and sends them with test procedure also

59. what is the difference between three tier and two tier application?

A:– Client server is a 2-tier application. In this, front end or client is connected to
‘Data base server’ through ‘Data Source Name’,front end is the monitoring level.

Web based architecture is a 3-tier application. In this, browser is connected to web server through TCP/IP and web server is connected to Data base server,browser is the monitoring level. In general, Black box testers are concentrating on monitoring level of any type of application.

All the client server applications are 2 tier architectures.
Here in these architecture, all the “Business Logic” is stored in clients and “Data” is stored in Servers. So if user request anything, business logic will b performed at client, and the data is retrieved from Server(DB Server). Here the problem is, if any business logic changes, then we
need to change the logic at each any every client. The best ex: is take a super market, i have branches in the city. At each branch i have clients, so business logic is stored in clients, but the actual data is store in servers.If assume i want to give some discount on some items, so i
need to change the business logic. For this i need to goto each branch and need to change the business logic at each client. This the disadvantage of Client/Server architecture.

So 3-tier architecture came into picture:

Here Business Logic is stored in one Server, and all the clients are dumb terminals. If user requests anything the request first sent to server, the server will bring the data from DB Sever and send it to clients. This is the flow for 3-tier architecture.

Assume for the above. Ex. if i want to give some discount, all my business logic is there in Server. So i need to change at one place, not at each client. This is the main advantage of 3-tier architecture.

Software Testing Interview Questions Part 4 »

By admin on Oct 18, 2007 in Software Testing Interview Questions Part 4 | 1 Comment

31. If we have no SRS, BRS but we have test cases does u execute the test cases blindly or do u follow any other process?
A: — Test case would have detail steps of what the application is supposed to do. SO
1) Functionality of application is known.

2) In addition you can refer to Backend, I mean look into the Database. To gain more knowledge of the application

32. How to execute test case?
A: — There are two ways:
1. Manual Runner Tool for manual execution and updating of test status.
2. Automated test case execution by specifying Host name and other automation pertaining details.

33. Difference between re testing and regression testing?

A: — Retesting: –

Re-execution of test cases on same application build with different input values is retesting.

Regression Testing:

Re-execution of test cases on modifies form of build is called regression testing…

34. What is the difference between bug log and defect tracking?
A; — Bug log is a document which maintains the information of the bug where as bug tracking is the process.

35. Who will change the Bug Status as Differed?
A: — Bug will be in open status while developer is working on it Fixed after developer completes his work if it is not fixed properly the tester puts it in reopen After fixing the bug properly it is in closed state.

Developer

36. wht is smoke testing and user interface testing ?

A: — ST:
Smoke testing is non-exhaustive software testing, as pertaining that the most crucial functions of a program work, but not bothering with finer details. The term comes to software testing from a similarly basic type of hardware testing.

UIT:
I did a bit or R n D on this…. some says it’s nothing but Usability testing. Testing to determine the ease with which a user can learn to operate, input, and interpret outputs of a system or component.

Smoke testing is nothing but to check whether basic functionality of the build is stable or not?
I.e. if it possesses 70% of the functionality we say build is stable.
User interface testing: We check all the fields whether they are existing or not as per the format we check spelling graphic font sizes everything in the window present or not|

37. what is bug, deffect, issue, error?

A: — Bug: — Bug is identified by the tester.
Defect:– Whenever the project is received for the analysis phase ,may be some requirement miss to get or understand most of the time Defect itself come with the project (when it comes).
Issue: — Client site error most of the time.
Error: — When anything is happened wrong in the project from the development side i.e. called as the error, most of the time this knows by the developer.

Bug: a fault or defect in a system or machine

Defect: an imperfection in a device or machine;

Issue: An issue is a major problem that will impede the progress of the project and cannot be resolved by the project manager and project team without outside help

Error:
Error is the deviation of a measurement, observation, or calculation from the truth

38. What is the diff b/w functional testing and integration testing?
A: — functional testing is testing the whole functionality of the system or the application whether it is meeting the functional specifications

Integration testing means testing the functionality of integrated module when two individual modules are integrated for this we use top-down approach and bottom up approach

39. what type of testing u perform in organization while u do System Testing, give clearly?

A: — Functional testing
User interface testing
Usability testing
Compatibility testing
Model based testing
Error exit testing
User help testing
Security testing
Capacity testing
Performance testing
Sanity testing
Regression testing
Reliability testing
Recovery testing
Installation testing
Maintenance testing
Accessibility testing, including compliance with:
Americans with Disabilities Act of 1990
Section 508 Amendment to the Rehabilitation Act of 1973
Web Accessibility Initiative (WAI) of the World Wide Web
Consortium (W3C)

40. What is the main use of preparing Traceability matrix and explain the real time usage?

A: — A traceability matrix is created by associating requirements with the work products that satisfy them. Tests are associated with the requirements on which they are based and the product tested to meet the requirement.

A traceability matrix is a report from the requirements database or repository.

41. How can u do the following 1) Usability testing 2) scalability Testing

A:–
UT:
Testing the ease with which users can learn and use a product.

ST:
It’s a Web Testing defn.allows web site capability improvement.

PT:
Testing to determine whether the system/software meets the specified portability requirements.

42. What does u mean by Positive and Negative testing & what is the diff’s between them. Can anyone explain with an example?

A: — Positive Testing: Testing the application functionality with valid inputs and verifying that output is correct
Negative testing: Testing the application functionality with invalid inputs and verifying the output.

Difference is nothing but how the application behaves when we enter some invalid inputs suppose if it accepts invalid input the application
Functionality is wrong

Positive test: testing aimed to show that s/w work i.e. with valid inputs. This is also called as “test to pass’
Negative testing: testing aimed at showing s/w doesn’t work. Which is also know as ‘test to fail” BVA is the best example of -ve testing.

43. what is change request, how u use it?

A: — Change Request is a attribute or part of Defect Life Cycle.

Now when u as a tester finds a defect n report to ur DL…he in turn informs the Development Team.
The DT says it’s not a defect it’s an extra implementation or says not part of req’ment. Its newscast has to pay.

Here the status in ur defect report would be Change Request

I think change request controlled by change request control board (CCB). If any changes required by client after we start the project, it has to come thru that CCB and they have to approve it. CCB got full rights to accept or reject based on the project schedule and cost.

44. What is risk analysis, what type of risk analysis u did in u r project?

A: — Risk Analysis:
A systematic use of available information to determine how often specified events and unspecified events may occur and the magnitude of their likely consequences

OR

procedure to identify threats & vulnerabilities, analyze them to ascertain the exposures, and highlight how the impact can be eliminated or reduced

Types :

1.QUANTITATIVE RISK ANALYSIS
2.QUALITATIVE RISK ANALYSIS
