Software Tester inwards a well-known company. I have got a doubtfulness regarding Regression Testing. Generally nosotros tell that Regression Testing way to examine whether whatever added functionality is affecting other functionalities or not. When functionality is added nosotros write assort examine cases for that as well as execute it. Here nosotros execute non solely the examine cases written for the novel functionality but also execute already passed examine cases to cheque whether other functionalities got affected or not.
I promise till hither I am correct. Now my inquiry is what testing approach should hold out applied if nosotros delete a functionality. Consider an example, a shopkeeper has a software. After calculating the cost of all the items purchased, when a push clit called "VAT" is pressed it adds 12.5% taxation to the cost as well as returns the full price. The software was made inwards that way because Indian Government enforces that dominion on shopkeeper.
Now if the authorities takes dorsum that VAT [Value Added Tax] rule, it is obvious that the shopkeeper volition no longer require that VAT functionality. So he asks to the software developer fellowship to withdraw that functionality. Now what approach the testing squad volition apply? Will Regression Testing come upward into the motion painting or Retesting volition hold out given importance?
This is a inquiry I received via electronic mail from 1 of my weblog readers today. Regression Testing is an often-misunderstood surface area of testing as well as testers acquire confused spell dealing amongst it. Some acquire confused betwixt retesting as well as regression testing, or as well as therefore nearly the approach to hold out followed spell regression testing, or as well as therefore nearly the examine cases (test areas) to comprehend spell regression testing as well as and therefore on. Even I did acquire confused inwards my before days of testing career. And likely I am yet to larn even as well as therefore to a greater extent than on the topic to beak similar an proficient on regression testing. Keeping that inwards mind, the side past times side paragraphs that are going to follow are my agreement of regression testing every bit at the fourth dimension of posting of this article.
What is Regression Testing?
Before nosotros tin give the axe hash out to a greater extent than on the plain of written report lets run into how others (some good respected manufacture experts/sources) depict as well as define regression testing:
1. Regression testing - Any repetition of tests (usually afterwards software or information change) intended to present that the software’s conduct is unchanged except insofar every bit required past times modify to the software or data. [B. Beizer, 1990]
2. Regression testing - Testing that is performed afterwards making a functional improvement or repair to the program. Its purpose is to decide if the modify has regressed other aspects of the program. [Myers, 1979]
3. Regression testing is whatever type of software testing which seeks to uncover regression bugs. Regression bugs tumble out whenever software functionality that previously worked every bit desired stops working or no longer industrial plant inwards the same way that was previously planned. Typically regression bugs tumble out every bit an unintended final result of computer program changes. Common methods of regression testing include re-running previously run tests as well as checking whether previously fixed faults have got re-emerged. [Automated testing tools tin give the axe hold out particularly useful for this type of testing. [Anonymous]
Sometimes I acquire a feeling [thanks to the tester friend who sparked this business of thought inwards a recent struggle on terminologies inwards software testing] that likely all the confusion involving the regression testing could have got been avoided to for certain extents if it were non called the way nosotros telephone phone it (as regression testing) today! The term "regression testing" seems similar a misnomer. It would hold out ameliorate if it were called something similar "anti-regression" or "progression" testing because the intention behind performing regression testing is to verify that the arrangement has non regressed to a worse state. “Regression” is defined inwards automated? Our opinions may vary. But at whatever rate, I would similar to take heed your ideas as well as opinions. Feel costless to phonation out your thoughts via commenting.
Wish y'all all Merry Christmas as well as a Happy as well as Prosperous New Year. Happy Testing…
