Basic Questions and Answers
1. What is meant by Priority and severity?
1. This is assigned by the Test Engineer
2. This is to say how badly the deviation that is occurring is affecting the other modules of
the build or release.
1. This is assigned by the Developer.
2. This is to say how soon the bug as to be fixed in the main code, so that it pass the basic
Egg. The code is to generate some values with some valid input conditions. The priority will
be assigned so based on the following conditions:
a> It is not accepting any value
b> It is accepting value but output is in non-defined format (say Unicode Characters).
A good example I used some Unicode characters to generate a left defined arrow, it displayed
correctly but after saving changes it gave some address value from the
Stack of this server. For more information mail me I will let you know.
2. Give me some example for Low severity and High priority defect?
If suppose the title of the particular concern is not spelled correctly, it would give a negative
impacted ICICC is spelled as a title for the project of the concern ICICI. Then it is a high
severity, low priority defect.
3. What is basis for test case review?
The main basis for the test case review is
1. Testing techniques oriented review
2. Requirements oriented review
3. Defects oriented review.
4. What are the contents of SRS documents?
Software requirements specifications and Functional requirements specifications.
5. What is difference between the Web application testing and Client Server testing?
Testing the application in intranet (without browser) is an example for client -server. (The
company firewalls for the server are not open to outside world. Outside people cannot access
the application.)So there will be limited number of people using that application.
Testing an application in internet (using browser) is called web testing. The application which
is accessible by numerous numbers around the world (World Wide Web.)
So testing web application, apart from the above said two testing there are many other
testing to be done depending on the type of web application we are testing.
If it is a secured application (like banking site- we go for security testing etc.)
If it is an e-commerce testing application we go for Usability etc…Testing.
6. Explain your web application architecture?
Web application is tested in 3 phases
1. Web tier testing –> browser compatibility
2. Middle tier testing –> functionality, security
3. Data base tier testing –> database integrity, contents
7.suppose the product/application has to deliver to client at 5.00PM,At that time you or your
team member caught a high severity defect at 3PM.(Remember defect is high severity)But the
client is cannot wait for long time. You should deliver the product at 5.00Pm exactly. Then
what is the procedure you follow?
The bug is high severity only so we send the application to the client and find out the severity
is priority or not. If its priority then we ask him to wait.
Here we found defects/bugs in the last minute of the delivery or release date
Then we have two options
1. Explain the situation to client and ask some more time to fix the bug.
2. If the client is not ready to give some time then analyze the impact of defect/bug and try to
find workarounds for the defect and mention these issues in the release notes as known
issues or known limitations or known bugs. Here the workaround means remedy process to
be followed to overcome the defect effect.
3. Normally this known issues or known limitations (defects) will be fixed in next version or
next release of the software
8. Give me examples for high priority and low severity defects?
Suppose in one banking application there is one module ATM Facility. In that ATM facility
whenever we are depositing/withdrawing money it is not showing any conformation message
but actually at the back end it is happening properly without any mistake means only missing
of message. In this case as it is happening properly so there is nothing wrong with the
application but as end user is not getting any conformation message so he/she will be
Confuse for this. So we can consider this issue as HIGH Priority but LOW Severity defects…
9. Explain about Bug life cycle?
2) Open defect->
3) Send to developer
4) ->if accepted moves to step5 else sends the bug to tester gain
5) Fixed by developer ->
6) Regression testing->
7) No problem inbuilt and sign off
->if problem in built reopen the issue send to step3

to fetch the data in the database and then compare the expected and actual.
11) What is the way of writing testcases for database testing?
Writing a testcases is like functional testing. First you have to know the functional
requirement of the application. Then you have to decide the parameters for writing testcases
Objective: Write the objective that you would like to test
Input method: Write the method of action or input you want to execute
Expected: how it should appear in the database
12) To manage and manipulate the test table what are the SQL statements that you have
used in Database testing?
The statements like SELECT, INSERT, UPDATE, DELETE are used to manipulate the table,
while ALTER TABLE, CREATE TABLE and DELETE TABLE are used to manage table.
13) How to test database procedures and triggers?
To test database procedures and triggers, input and output parameters must be known.
EXEC statement can be used to run the procedure and examine the behaviour of the tables.
Open the database project in solution explorer
Now in View menu, click the database schema
Open the project folder from schema View menu
Right click on the object that has to be tested, and then click on the dialog box that
says Create Unit Tests
After that create a new language test project
Select either a) Insert the unit test or b) Create a new test and then click OK
Project that has to be configured will be done by clicking on the Project Configuration
Once it configured click on OK
14) How you can write testcases from requirements and do the requirements represents
exact functionality of AUT (Application Under Test)?
To write a testcases from requirements, you need to analyse the requirements thoroughly in
terms of functionality. Thereafter you think about the appropriate testcases design
techniques like Equivalence partitioning, Black box design, Cause effect graphing etc. for
writing the testcases.
Yes, the requirements represent exact functionality of AUT.
15) What is DBMS?
DBMS stand for Database management system, there are different types of DBMS
16) What is DML?
DML stands for Data Manipulation Language, It is used to manage data with schema objects.
It is a subset of SQL.
17) What are DCL commands? What are the two types of commands used by DCL?
DCL stands for Data Control Language, it is used to control data.
The two types of DCL Commands are:
Grant: By using this command user can access privilege to database
Revoke: By using this command user cannot access the database
18) What is white box testing and black box testing?
Black box testing means testing the software for the outputs on giving particular inputs. This
testing is usually performed to see if the software meets the user’s requirements. There is no
specific functional output expected for running this test.
The white box testing is done to check the accuracy of code and logic of the program. This
testing is done by the programmer who knows the logical flow of the system.
19) How does QTP evaluate test results?
Once the testing is done, QTP will generate a report. This report will show the checkpoints,
system message and error that were detected while testing. The test results window will
show any mismatches encountered at the checkpoints.
20) Explain the QTP testing process?
QTP testing process is based on following steps:
Creating GUI (Graphical User Interface) Map files : Identifies the GUI object which has
to be tested
Creating test scripts: Test scripts are recorded
Debug tests: Test should be debugged
Run tests: Testcases should be run.
View results: The results reflects the success or failure of the tests
Report detects: If the test is failed, the reasons will be recorded in the report detect
21) What is load testing and give some examples of it?
To measure the system response, load testing is done. If the load exceeds the users pattern
it is known as stress testing. Examples of load testing are downloading the set of large files,
executing multiple applications on a single computer, subjecting a server to large number of
e-mails and allotting many tasks to a printer one after another.
22) How to test database manually?
Testing the database manually involves checking the data at the back end and to see whether
the addition of data in front end is affecting the back end or not, and same for delete, update,
23) What RDBMS stands for and what are the important RDMBS that SQL use?
RDBMS stands for Relational Database Management Systems that use SQL, and the
important RDBMS that SQL uses are Sybase, Oracle, Access ,Ingres, Microsoft SQL server
24) What is performance testing and what are the bottlenecks of performance testing?
Performance testing determines the speed of the computer system performance. It includes
the quantitative tests like response time measurement. The problem in performance testing is
that you always need a well-trained and experienced man power also the tools you use are
25) What is DDL and what are their commands?
To define database structure, DDL is used. DDL stands for Data Definition Language. The
various DDL commands include Create, Truncate, Drop, Alter, Comment and Rename.
What is the difference between Functional and Non-functional testing?
Functional Testing covers:
• Unit Testing
• Smoke testing / Sanity testing
• Integration Testing (Top Down, Bottom up Testing)
• Interface & Usability Testing
• System Testing
• Regression Testing
• Pre User Acceptance Testing(Alpha & Beta)
• User Acceptance Testing
• White Box & Black Box Testing
• Globalization & Localization Testing
Non-Functional Testing covers:
• Load and Performance Testing
• Ergonomics Testing
• Stress & Volume Testing
• Compatibility & Migration Testing
• Data Conversion Testing
• Security / Penetration Testing
• Operational Readiness Testing
• Installation Testing
• Security Testing (Application Security, Network Security, System Security)
According to me
Functional Testing:Functional testing is what a system is supposed to do?
Non-Functional Testing means How a system is supposed to do?
I will give an example regarding both functional and non-functional testing.Suppose you send
an email to an user .Here the functional testing is to check the email is going to the proper
email tht you have specified or not.But the non-functional testing is to how the system send
the email to the specified address,what are the protocols used to send an email..
I think you will get a fair idea about functional and non-functional testing.

Tips on Localization Testing
Do you know:
A little care at pre release stage of a localized Software product can save precious dollars !!
Software Localization Services is as important as software development. We at QA InfoTech
understand that Testing software in a particular language necessarily entails providing all
inputs in that language. By entering data in localized characters, a tester cleanses the
process to a great extent and ensures the end user doesn’t waste time over possible errors.
At QA InfoTech, we have ample experience of localized testing of software. We have a
partnership with universities and experienced linguists who help us understand the subtle
differences in the languages and cultures.
- Our Globalization experts analyze the product code to establish its existing
internationalization level and validated by our testing experts who run manual or script based
tests as well.
- Our aim is to validate products so that they offer proper functionality across different
languages. Proper functionality ensures that the internal design of the product is such that it
performs the same functions regardless of international environment settings or
cultures/locales and the correct representation of data.
- Expertise on Localization Testing of bi-directional languages.
Our functional and cosmetic checks ensure that the product is validated and verified in the
local language and issues if any are successfully regressed. For more info, please visit:
Localization is the process of adapting a globalized application to a particular culture/locale.
Localizing an application requires a basic understanding of the character sets typically used
in modern software development and an understanding of the issues associated with them.
Localization includes the translation of the application user interface and adapting graphics
for a specific culture/locale. The localization process can also include translating any help
content associated with the application.
Localization of business solutions requires that you implement the correct business
processes and practices for a culture/locale. Differences in how cultures/locales conduct
business are heavily shaped by governmental and regulatory requirements. Therefore,
localization of business logic can be a massive task.
Localization testing checks how well the build has been translated into a particular target
language. This test is based on the results of globalized testing where the functional support
for that particular locale has already been verified. If the product is not globalized enough to
support a given language, you probably will not try to localize it into that language in the first
Localization Testing in the software testing process for checking the localized version of a
product (e.g., Japanese product for Japanese user). Localization Testing checks the quality
of a localized version for a particular that culture/locale setting. Localization Testing is based
on the results of Globalization Testing which verifies the functional support for that particular
culture/locale setting. We should invite the local staff to help our localization testing by
checking the quality of translation as well
