Regressing Testing Interview Questions and Answers for Fresher
Ans:- This is black box testing where the performance of an application is checked by giving certain inputs and generate the desired outputs. The objective of functional testing is validating the behavior of the application based on documents specifications and it also checks either application is ready to release in a specific environment or not.This is an important answer to these kinds of functional testing interview questions and answers.
Ans:- A few popular functional testing techniques are –
Unit Testing, Smoke Testing, Regressing Testing, usability testing, integration testing, system testing, user acceptance testing, etc.
Ans:- This is a simple process of repeating test cases that is performed every time you modify the application functionality. It may be your code, design, or any other things related to the framework. The regression testing makes sure that changes will not impact or break the application functionality. So, every time new version of an app is created, the bugs are fixed automatically.This is an important answer to these kinds of functional testing interview questions and answers.
Ans:- Well, the best part is that it can be done in both ways either manually or automatically. You just have to check which technique suits your project requirements the most.This is an important answer to these kinds of functional testing interview questions and answers.
Ans:- You are established with regression testing means repeating a set of test cases at any particular situation. When the app is small, regression testing can be performed manually. As the time moves on, the application starts getting more complicated and you need testing tools to speed up the process. In this case, regression testing is automated based on document specification.
Ans:- Every time changes are committed to an application or software program; the following steps need to perform to carry out the regression testing. These are –

Ans:- Every time when a programmer adds the new code to fix the previous bug, several new bugs are introduced simultaneously. The objective of Regression Testing is to check where the new code complies with the older ones. The application behavior should be as per expectation otherwise changes are discarded immediately. For this purpose, this is necessary that testing should be completed on time before the product is released onto the market. This is a continuous process and should be taken as the routine activity during application development. This is an important answer to these kinds of functional testing interview questions and answers.
Ans:- Well, it depends on application nature and scope of changes. If the scope is large then testing needs to perform thoroughly and it will take time. The complete information can be obtained from the developer about the scope, nature of applications, the total amount of change.
Ans:- As this a repetitive tests process, a set of test cases can be used again for a new build. Keep in mind that selection of test cases should be done carefully and a number of counts also needs to be minimum. They should be improved continuously to meet the expectations of the new app.
If the scope of changes is large the continuous improvement may be difficult and needs extra efforts by testers. For this purpose, selective test cases will be used to save the overall time and money. These test cases are selected on the basis where it affects the most.
Ans:- Mostly, the regression testing is carried out throughout the development process and this is a continuous process too. Still, the best time to perform regression testing is after smoke testing or at the end of function testing after a short release.This is an important answer to these kinds of functional testing interview questions and answers.
Well, as I told you, Sprints are very quick, so we need to balance the sprint development and regression testing. My choice is to go with Automation so that we can overcome this problem.
First, I’ll review the regression suite, will make necessary changes if required. Then will calculate the time for execution.
Well, I cannot say exactly, since it depends on project complexity, but I can guess, it follows 10:30:60 order.
Sure, I worked in the Payment Gateway module, so whenever a new gateway is added, I’ve two things to do, first, one is to re-run all test cases, or identifying impacted areas like Checkout Process, Email confirmations, OTPs and testing them. So once I have done with regression of prone areas, if required I’ll go with end to end regression for a complete module, otherwise NO.
So, build by build release, We less care about existing modules are working fine. But this is not the case always, sometimes, newly added features are going to disturb the existing functionality.
How to do Regression Testing
In order to do Regression Testing process, we need to first debug the code to identify the bugs. Once the bugs are identified, required changes are made to fix it, then the regression testing is done by selecting relevant test cases from the test suite that covers both modified and affected parts of the code.
Software maintenance is an activity which includes enhancements, error corrections, optimization and deletion of existing features. These modifications may cause the system to work incorrectly. Therefore, Regression Testing becomes necessary. Regression Testing can be carried out using the following techniques:
Regression Test Selection is a technique in which some selected test cases from test suite are executed to test whether the modified code affects the software application or not. Test cases are categorized into two parts, reusable test cases which can be used in further regression cycles and obsolete test cases which can not be used in succeeding cycles.
