QA Interview Question And Answers:

Q.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

Q.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.

Q.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.

Q.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

Q.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.

Q.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.

Q.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.

Q.What is Agile testing and what is the importance of Agile testing?

Agile testing is software testing, which involves the testing of the software from the customer point of view. The importance of this testing is that, unlike normal testing process, this testing does not wait for development team to complete the coding first and then doing testing. The coding and testing both goes simultaneously. It requires continuous customer interaction. It works on SDLC ( Systems Development Life Cycle) methodologies, it means that the task is divided into different segments and compiled at the end of the task.

Q.How does a server or client environment affect software testing?

As the dependencies on the clients are more, the client or server applications are complex. The testing needs are extensive as servers, communications and hardware are interdependent. Integration and system testing is also for a limited period of time.

Q.What are the tools used by a tester while testing?

YSlow for FireBug
Web Developer toolbar for firebox

Q.Explain stress testing, load testing and volume testing?

Load Testing: Testing an application under heavy but expected load is known as Load Testing. Here, the load refers to the large volume of users, messages, requests, data, etc.
Stress Testing: When the load placed on the system is raised or accelerated beyond the normal range then it is known as Stress Testing.
Volume Testing: The process of checking the system, whether the system can handle the required amounts of data, user requests, etc. is known as Volume Testing.

Q.What are the five common solutions for software developments problems?

Setting up the requirements criteria, the requirements of a software should be complete, clear and agreed by all The next thing is the realistic schedule like time for planning , designing, testing, fixing bugs and re-testing Adequate testing, start the testing immediately after one or more modules development. Use rapid prototype during design phase so that it can be easy for customers to find what to expect Use of group communication tools

Q.What is a ‘USE’ case and what does it include?

The document that describes, the user action and system response, for a particular functionality
is known as USE case. It includes revision history, table of contents, flow of events, cover
page, special requirements, pre-conditions and post-conditions.

Q.What is CRUD testing and how to test CRUD?

CRUD testing is another name for Black Box testing. CRUD stands for Create, Read, Update

Q.What is validation and verification in software testing?

In verification, all the key aspects of software developments are taken in concern like code,
specifications, requirements and document plans. Verification is done on the basis of four
things list of issues, checklist, walkthroughs and inspection meetings. Following verification,
validation is done, it involves actual testing, and all the verification aspects are checked
thoroughly in validation.

Q.What is thread testing?

A thread testing is a top-down testing, where the progressive integration of components follows
the implementation of subsets of the requirements, as opposed to the integration of components
by successively lower levels.

Q.Explain what are test driver and test stub and why it is required?

The stub is called from the software component to be tested, it is used in top down approach The driver calls a component to be tested, it is used in bottom up approach It is required when we need to test the interface between modules X and Y and we have developed only module X. So we cannot just test module X but if there is any dummy module we can use that dummy module to test module X Now module B cannot receive or send data from module A directly, so in these case we have to transmit data from one module to another module by some external features. This external feature is referred as Driver
