It is estimated that Apple has 2.2million apps and Google Play has 2.8 million apps available for download. This shows that brands or non-brands rely on mobile apps phone apps to extend their services to their customers. As per the records, 54% of people tend to uninstall the app if it takes more than 3 seconds of loading time. Slightest Compromise in the mobile app testing might prove fatal. Inclusion of Regression testing in your software development lifecycle will eliminate the slightest bug causing hurdles in the seamless performance of your app.

What is Regression Testing?

Before defining regression testing let me define the word regression, regression in software is an unintended change that occurs due to the implementation of a new feature. Regression Testing is nothing but the hunting of these changes that might occur disrupting the existing functionality of the software.

Types of Regression Testing

Depending on the factors such as changes introduced, the number of bugs fixed, etc. Regression testing can be performed in the following ways:

Unit Regression Testing

Unit testing is performed on only a code unit, for example, a class or a method while disabling all other code units.

Corrective Regression Testing

This type of testing is performed when there are no changes introduced in the specification of the product, also an existing set of test cases can be reused to conduct this testing.

Selective Regression Testing

This type of testing is done during the introduction of the new functionality of the software i.e. there is a change in the specification of the software. Also, new test case management tools are prepared to perform this testing. This type of testing is done to ensure that no features in the existing software have been compromised in the updated version.

Progressive Regression Testing

This type of testing is done during the introduction of the new functionality of the software i.e. there is a change in the specification of the software. Also, new test cases are prepared to perform this testing. This type of testing is done to ensure that no features in the existing software have been compromised in the updated version.

Complete Regression Testing

This type of testing is especially done when multiple changes have been introduced in the existing software. Also, this type of testing is performed when there is an impact on the root code of the software. This type of software is highly beneficial to eliminate unexpected bugs. After performing this type of testing, the product is made available to the user.

The need for Automating Regression Testing

After having a look at the types of regression testing, it is obvious that they are time-consuming and tedious. Hence regression testing may cause testers to lose interest and make the complete process boring resulting in inefficient outcomes. Hence automating regression testing will be a much better option in fetching efficient results. Also, the automation of regression testing can be cost-effective.

Tools for performing Automation Regression Testing

Let’s have a look at the most popular tools used for automated regression testing.

Katalon Studio

Katalon Studio is an all-in-one automation tool for performing regression testing on websites, web-browser, and mobile applications. It supports running scripts on multiple devices, browsers, and environments. This end to end automation solution will simplify the regression testing for testers.

Selenium

In selenium, you can run automated test scripts that cycle through data sets and data-driven tests. It is one of the best tools for performing browser-based and cross-platform regression testing.

Watir

Web Application testing on ruby is an open-source library using Ruby as the programming language. This platform is no less than a treasure for testers as it provides diverse user interaction capabilities for website testing such as clicking links, filling out forms and validate tests on a variety of browsers.

Apache JMeter

Apache JMeter is capable of performing load and performance tests on many different applications. It also provides a complete regression test suite for the end-user.

Above mentioned tools are no less than a boon for performing automated regression testing On mobile applications. So do make note of it to make your testing life effortless and getting efficient end results.
