As technology is advancing, the need for quality and up to date software is increasing. But most of the time during a change in technology or any up gradation some unknown bug arises which needs to be tested and resolved as quickly as possible.

But how do testers do this, especially after every change? This is where regression test helps.

Let’s now take a deeper look into what exactly is regression test, what are the regression testing techniques, and what are different types of regression test tools used in the software industry in the year 2021.

What is regression testing?

Regression testing is a software testing type that involves re-running functional and non-functional tests.

The main aim of the regression test is to ensure that any code change in the software does not affect the existing functionalities of the software.

Regression test should be taken up in following situation:

Whenever any new functionality is added to the software
Whenever any change is made in the existing functionalities of the software
Whenever software is integrated with other products or code is optimized

What are the regression testing techniques?

Below mentioned are the different types of regression testing techniques:

Retest all – In this technique, the test engineers execute all the existing test cases. This technique consumes a lot of time and effort.

Regression test selection – In this technique, test engineers select a subset of test cases. The test cases are of two types: obsolete test cases and reusable test cases.

Test case prioritization – In this technique, test engineers prioritize the test cases based on business impact and used functionalities

How to achieve an effective regression test?

Regression test can be done in two ways, i.e. manual regression test and automated regression test. Since, the regression test process takes a lot of time and effort of tester due to repetition of tasks, it is advised to automate the regression test.

Automated regression test not only makes the test process fast, but it also eliminates the chances of human prone errors, and thus, makes the testing process effective and reliable.

Automated regression testing is done with the help of automated regression test tools.

There are a variety of tools available today, however, it is advised to select the right tools that match the business goal and objective.

What are the regression testing tools?

Let’s now look at some of the regression test tools that businesses can leverage in 2021

Selenium: Selenium is an open-source test automation suite for web applications. It supports various platforms and browsers. It includes Selenium IDE, WebDriver and, Selenium Grid.

It is considered an industry standard and one of the favorite tools for regression test by testers all over the world.

Ranorex Studio: Ranorex studio is a regression test tool that can be used for desktop, web, and mobile apps.

Ranorex Studio offers codeless test automation. It has object recognition capabilities, a shareable object repository, and supports data-driven tests.

It produces easy-to-read test reports that are fully customizable and include screenshots, detailed error logs, and video capture.

TestComplete: TestComplete is one of the easy to use regression test tools. It supports various scripting languages like Python, Javascript, C++Script, C# Script, etc.

This tool provides maximum test coverage with a hybrid object and visual recognition engine. It also has a record and replays feature which helps in creating automated UI tests.

With this tool, you can have access to over 1000 operating systems, browsers, and resolution configurations.

Test Sigma: TestSigma is an ideal automated regression test tool. It automatically suggests affected test cases after every enhancement or bug fix.

This tool lets testers run regression tests right after first check-ins, automatically within a sprint. It comes with some amazing features such as scriptless testing in the native English language. It allows the creation of regression test suites using automatic suggestions of test cases.

It allows easy test report generation. It has a centralized object repository to easily track and rectify locator issues. It can easily be integrated with CI/CD tools, Jenkins, JIRA, Slack, etc.

Watir: Watir i.e.; Web Application Testing in Ruby is an open-source Ruby library for automating tests. It interacts with a browser the same way people do by clicking links, filling out forms, and validating text.

It is an open-source regression test tool. It can be used to automating regression test suite. It supports multiple browsers, platforms, and OS.

Conclusion: Regression testing is an essential part of the software testing process. This testing type not helps in making the product bug-free but also helps to improve the reliability, robustness of the software after each update.

Various tools can leverage to automate the regression test however the choice of the tool completely depends on business and project needs. Leverage regression testing from a next-gen QA and software testing services provider to achieve quality products.
