1) What is the difference between the QA and software testing?
The role of QA (Quality Assurance) is to monitor the quality of the process to produce a quality of a product. While the software testing, is the process of ensuring the final product and check the functionality of final product and to see whether the final product meets the user’s requirement.
2) What is Testware?
Testware is the subset of software, which helps in performing the testing of application. It is a term given to the combination of software application and utilities which is required for testing a software package.
3) What is the difference between build and release?
Build: It is a number given to Installable software that is given to testing team by the development team.
Release: It is a number given to Installable software that is handed over to customer by the tester or developer.
4) What are the automation challenges that QA team faces while testing?
Exploitation of automation tool
Frequency of use of test case
Reusability of Automation script
Adaptability of test case for automation
5) What is bug leakage and bug release?
Bug release is when software or an application is handed over to the testing team knowing that the defect is present in a release. During this the priority and severity of bug is low, as bug can be removed before the final handover.
Bug leakage is something, when the bug is discovered by the end users or customer, and missed by the testing team to detect, while testing the software.
QA Interview Questions
6) What is data driven testing?
Data driven testing is an automation testing part, which tests the output or input values. These values are read directly from the data files. The data files may include csv files, excel files, data pools and many more. It is performed when the values are changing by the time.
7) Explain the steps for Bug Cycle?
Once the bug is identified by the tester, it is assigned to the development manager in open status
If the bug is a valid defect the development team will fix it and if it is not a valid defect, the defect will be ignored and marked as rejected
The next step will be to check whether it is in scope, if it is happen so that, the bug is not the part of the current release then the defects are postponed
If the defect or bug is raised earlier then the tester will assigned a DUPLICATE status
When bug is assigned to developer to fix, it will be given a IN-PROGRESS status
Once the defect is repaired, the status will changed to FIXED at the end the tester will give CLOSED status if it passes the final test.

7) How would you know for database testing, whether trigger is fired or not?
On querying the common audit log you would know, whether, a trigger is fired or not. It is in audit log where you can see the triggers fired.
In data base testing, what are the steps to test data loading?
Following steps need to follow to test data loading
Source data should be known
Target data should be known
Compatibility of source and target should be checked
In SQL Enterprise manager, run the DTS package after opening the corresponding DTS package
You have to compare the columns of target and data source
Number of rows of target and source should be checked
After updating data in the source, check whether the changes appears in the target or not.
Check NULLs and junk characters
9) Without using Database Checkpoints, how you test a SQL Query in QTP?
By writing scripting procedure in VBScript, we can connect to database and can test the queries and database.
10) Explain how to use SQL queries in QTP ?
In QTP using output database check point and database check, you have to select the SQL manual queries option. After selecting the manual queries option, enter the “select” queries 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 like
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 dialog box.
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

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 file
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, insert etc.
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 etc.
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 expensive.

Hi All,
According to me
Functional Testing:Functional testing is what a system is supposed to do?
e.g. interoperability
Non-Functional Testing means How a system is supposed to do?
e.g. Eficiency,accuracy.
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 place.
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.
