Testing Interview Questions

1. Differentiate between QA and QC?

QA: It is process oriented
It evolves in entire process of software development.
Preventing oriented.
QC:
It is product oriented.
Work to examine the quality of product.
Deduction oriented.

2. What is a bug?
A computer bug is an error, flaw, mistake, failure, or fault in a computer program that prevents it from working correctly or produces an incorrect result.

3. What is a test case?
Test case is set of input values, execution preconditions, expected results and execution
Post conditions, developed for a particular objective or test conditions, such as to exercise a particular program path or to verify compliance with a specific requirement.

4. What is the purpose of test plan in your project?
Test plan document is prepared by the test lead, it contains the contents like introduction, objectives, test strategy, scope, test items, program modules user procedures, features to be tested features not to tested approach, pass or fail criteria, testing process, test deliverables, testing, tasks, responsibilities,resources,schedule, environmental requirements, risks & contingencies, change management procedures, plan approvals, etc all these things help a test manager understand the testing he should do & what he should follow for testing that particular project.

5. When the relationships occur between tester and developer?
Developer is the one who sends the application to the tester by doing all the necessary code in the application and sends the marshal id to the tester. The tester is the one who gives all the input/output and checks whether he is getting required output or not. A developer is the one who works on inside interfacing where as the tester is the one who works on outside interfacing

6. When testing will starts in a project?
The testing is not getting started after the coding. After release the build the testers perform the smoke test. Smoke test is the first test which is done by the testing team. This is according to the testing team. But, before the releasing of a build the developers will perform the unit testing.

7. If a bug has high severity then usually that is treated as high priority, then why do priority given by test engineers/project managers and severity given by testers?
High severity bugs affects the end users ….testers tests an application with the users point of view, hence it is given as high severity. High priority is given to the bugs which affects the production. Project managers assign a high priority based on production point of view.

8. What is the difference between functional testing and regression testing?
Functional testing is a testing process where we test the functionality/behaviour of each functional component of the application…i.e. minimize button, transfer button, links etc.i.e we check what is each component doing in that application…
Regression testing is the testing the behaviour of the application of the unchanged areas when there is a change in the build.i.e we check whether the changed requirement has altered the behaviour of the unchanged areas. The impacted area may be the whole of the application or
Some part of the application…

9. Do u know about integration testing, how does u integrate different modules?
Integration testing means testing an application to verify the data flows between the modules. For example, when you are testing a bank application, in account balance it shows the
100$as the available balence.but in database it shows the 120$. Main thing is “integration done by the developers and integration testing done by the testers”

10. do u know about configuration management tool, what is the purpose of maintaining all the documents in configuration management tool?
It is focused primarily on maintaining the file changes in the history.
Documents are subjected to change for ex: consider the Test case document.
Initially you draft the Test cases document and place it in Version control tool (Visual Source Safe for ex).Then you send it for Peer Review .They will provide some comments and that document will be saved in VSS again.Similary the document undergoes changes and all the changes history will be maintained in Version control.
It helps in referring to the previous version of a document.
Also one person can work on a document (by checking out) at a time.
Also it keeps track that has done the changes, time and date.
Generally all the Test Plan, Test cases, Automation design docs are placed in VSS.
Proper access rights needs to be given so that the documents don’t get deleted or modified.

11. How you test database and explain the procedure?
Database Testing is purely done based on the requirements. You may generalize a few features but they won’t be complete. In general we look at
1. Data Correctness (Defaults)
2. Data Storage/Retrieval
3. Database Connectivity (across multiple platforms)
4. Database Indexing
5. Data Integrity
6. Data Security

12. Suppose if you press a link in yahoo shopping site in leads to some other company website? How to test if any problem in linking from one site to another site?
1) First I will check whether the mouse cursor is turning into hand icon or not?
2) I will check the link is highlighting when I place the cursor on the link or not?
3) The site is opening or not?
4) If the site is opening then I will check is it opening in another window or the same window that the link itself exist (to check user-friendly ness of the link)
5) How fast that website is opening?
6) Is the correct site is opening according to the link?
7) All the items in the site are opening or not?
All other sub links are opening or not?

13. What are the contents of FRS?
F ? Function Behaviours
R ? Requirements (Outputs) of the System that is defined.
S ? Specification (How, What, When, Where, and Way it behavior’s.
FRS ? Function Requirement Specification.
This is a Document which contains the Functional behavior
of the system or a feature. This document is also known as EBS External Behaviour Specification - Document. Or EFS External Function Specification.

14. What is meant by Priority and severity?
Priority means “Importance of the defect w.r.t customer requirement”
Severity means “Seriousness of the defect w.r.t functionality”
