Testing Basics Interview Questions

Number of confirmed defects detect in software.

Defect density is a project metrics to find out the number of defects per linos of code that programmer has written. This is an improvment process to efficiently improve the developer

High Severity & Low priority defect: An error which occurs on the functionality of the application (for which there is no workaround) and will not allow the user to use the system but on click of link which is rarely used by the end user.

High severity:required functionality is missing but testing can continue workarounds are done but product can not deliver without fixing
Low priority:bugs impacts minor component of the employees work and work around has been implimented.

V - Model follows Verification and Validation as static testing and dynamic testing respectively.

Hi,
In the V model each model is Testable and Each have review. so , we can easily find a bug and also we can add new requirement at ant phase. the shape of Design is Vshape,so it is called V model.

Alpha Testing: 1. Alpha Testing is testing which is carried out in development environment. 2. Testing is performed in presence of Developer therefore more controlled environment. Beta Testing: 1. Be...

1)Alpha- Conducted by a Specific customer 1) Beta-conducted by customer live people

2)Alpha-Conducted in Virtual environment 2) Beta-Conducted in Real time environment

3)Alpha- Conducted on Application i.e before release 3) Beta-conducted for products i.e after release

TESTING: A must know terms 1. What is Regression testing? 2. What is re-testing? 3. What is STATIC and Dynamic testing? 4. What is Functional and non-functional testing? 5. What is Structural testing...

Testing types * Functional testing here we are checking the behavior of the software. * Non-functional testing here we are checking the performance, usability, volume, security. Testing methodologie...

Equivalence Partioning:- i) Equivalence Partition determines the number of test cases to be generated for a given scenario. ii) It has to be supplemented by Boundary Value Analysis. iii) Equivalence P...

BVA:To check size or range of i/p field.
EQA:To check type of i/p or o/p field.

NFR: Non Functional Requirement is perquisite doc for PT. It define SLA, entry and exit criteria of PT.

Business requirements doc and functional requirements doc. Business requirements details the high-level requirements from business standpoint. So some of these would eventually become transactions du...

Should be a good communicator
should have enough knowledge on which he/she is working
should have guts to say no

should have the ability to think beyond the normal

Must be aggressive on finding defect
Must have strong desire for quality
Must use tact and diplomacy to maintain a cooperative relationship with developers.
Must be able to communicate with technical and non technical people.

Types of Review:

there are five which are as follows.

1.Self study review
2. Context review
3. Historical review
4. Theoretical review
5. Integrate review

Types of review
Formal and Informal.
They may be Technical or Managerial
Technical review may be Inspection and Walk-through

System Testing: It should be done by the testers. During this testing process tester will verify the correctness of the system. System testing is implemented by various testing techniques. 1.GUI testi...

To put in a nutshell, Functional Testing is software design based testing; UAT is requirements based testing. System Test is done as by IT testing team and they need to certify that the application c...

Regression testing is done to check the bug fixes or the changes on modified application build is not disturbing the existing functionality of an application.

Re-Testing is done to check on the same build with multiple data sample to check the robustness (stable enough) of the application

Retesting/Confirmation Testing is done to check whether the Failed tc/Failed Functionality is working fine after the fix. Regression Testing is done to check whether any of the other functionality is...

Test case is a set of conditions we write for which we know the expected output.It may be negative or positive. For ex: (To enter username) case: ...

Test Cases are collection of instructions which are recorded only for verifying some certain functionality.

These are derived from test condition.

And Test scripts tells about which test case will be executed first means the sequence.

Test scripts are otherwise called as test procedure.

Bugs are classified as

1. Feature bugs
2. Data bugs
3. Coding bugs
4. Interface,integration and system bugs
5. Test and design bugs
6. Structural bugs
* Control and sequence bugs
* Logic bugs
* Processing bugs
* Initialization bugs
* Data flow and anomalies

Bug is nothing but, while executing a test case if we found any unexpected result which is not matching to expected result. This is as per Tester view If a developer is performing the unit testing, ...

Functional testing (also known as black-box testing), is a software testing approach in which: 1. the tester will have a user perspective in mind, 2. not knowing and doesn't mind how the program work...

Structural testing is a white box testing. where a tester looks into the code and performs the testing.Functional testing is a black  box testing. where a tester  performs testing without lo...

Wow! Never heard of such question!

One question to you: where and how did you come up with this question.

No one cares about the # pages in a document. All you and everyone should be care about is the "test strategy" to best test the application.

The answer to this question varies between companies and even divisions within companies.  In my company, the test strategy is typically between 5 and 10 pages.  It is a high level...

@Kalayan_M : It would be great if you can explain terms by using examples. We all understand concepts well when examples are used. Clearly, you do not understand domain or how to test it. You just se...

Domain refers to a body of knowledge in a particular field or industry.Domain testing are testing activities that require knowledge of an industry's domain.  For example, testing a banking ap...

As "kurtz182" rightly mentioned; test passes are test iterations. QA runs a group of test cases or just one big single test cases to test a feature. This "run" is called test iteration or test run. ...

'Test pass' is nothing but a 'test cycle' or 'test iteration' in the Execution phase.

All these kind of questions stem from not having real-time experience. Trust me when you join a company all these will vanish from your mind! Manual or automation, you as QA have to log the bug. It ...

Generally Bugs are reported with the help of Bug Tracking tools ( Like bugzilla, TeamTrack, Test Director ,Quality Centre or any other such tools)

You can also have your organization built in tools.

or you can use excel sheets also.
