Automated Vs. Manual Regression Testing

Automated Vs. Manual Regression Testing: How Does The Automation Testing Change The Process

In the world of software testing, manual testing was the king, but that was until the emergence of automated testing. Although manual testing has benefits and remains useful, automation testing provides more advantages to developers and quality assurance testers. Additionally, it increases the number of tests developers can perform, which is crucial with the multiplication of different operating systems, devices, and websites. 

This is not to say that manual testing has no merits. Manual testing still plays a crucial part that automation testing cannot provide. With manual testing, testers have to sit and go through lines of code one by one. Naturally, this is time-consuming and stressful. 

Sometimes a tired tester may not notice a defect. Still, with automation testing, the level of accuracy is increased. Because it runs automatically, it saves time for the tester. Time is necessary for software testing, and with the time-saving abilities of automated testing, developers can now meet software release deadlines. Nevertheless, selecting between manual and automation testing depends on what you are looking for; each test has its niche. 

Understanding Manual Regression Testing

Manual regression testing is the traditional way of testing. Here testers look out for the bugs in software by following a test plan with sets of various test cases. The prospect varies when using automated regression testing tools, which allows for faster and more efficient testing, as the tests can be executed repeatedly with minimal human intervention.

When done manually, the testers act like the end-user and check the behavior of the mobile app or website from the end-users point of view. After they have analyzed the app from the end user’s point of view, checking if its functionality is as intended and analyzing to see if there are any bugs, they report any inconsistency or discrepancy as an error to the developers. 

The developer’s job is to identify these errors and then fix them. This is not as straightforward as there is often pressure from several teams to point out different errors and bugs that require the developer’s attention. Manual testing is often used when behavioral or cognitive abilities are required to check the software’s functionality. In other words, it can test user acceptance, website and app behavior, functionalities, features, user interface (UI), and user experience (UX).

What Is Automated Regression Testing

Automated regression testing is a software testing method that verifies if an app is functioning as intended after adding new features, code, or improvement. Testers use appropriate automation tools in automated regression testing to develop the test scripts and validate the software. Automated regression testing is a software regression testing technique often used to automate the application of scripts, plans, workflows, and other activities. It covers many workflows and checks the processes to ensure that the software functions properly after the update. It also tests the workflow and identifies functional areas.

Unlike manual testing, automation testing uses frameworks to run tests. Every one of these frameworks is scripted with the rules of automation pertaining to the software to be tested. Various components infused in this framework include test data sources, object details, function libraries, and reusable modules. 

Although automated regression testing is now widely used, there are still areas in which it is best to stick to manual regression testing. However, when using automation regression testing, it is best to test the cases multiple times to detect any issue with the software. Repeating the testing, the developer confirms that the test case is completely validated and functioning as intended.

Importance Of Automation Testing

There are several reasons why developers favor automated regression testing. For one, automated testing tools can run a number of tests while the developer searches for the error. 

The key importance of automated testing is its presence in a faster approach to testing than manual testing. It does not allow random testing. Also, automated regression testing is more reliable as it is done with scripts and tools. Unlike manual testing, there is no fatigue or errors. Over time automated testing has ended The liability by being more accurate in testing. 

Admittedly, automated irrigation testing can be cost-intensive, but the return on investment is worth it. Automated regression testing comes in handy when the scale of testing is large. It is also cost-efficient. Because the testing is mostly run by scripts already written down, developers do not need to sit in front of a system. This means that testing can be done any time, twenty-four hours a day, seven times 7 days a week.


Software is designed in a very unique way, that any small unprecedented change in it can lead to errors in the overall product. 

This is why it is crucial for businesses and companies to perform manual or automated regression testing depending on the developer’s needs. 

For more accurate results, a developer must understand the specifics of every functionality; this will help save a lot of time.
