Leverage Regression Testing to bring the quality of your digital products to the next level!


What is Regression Testing?

Every little change in the software and code of your digital product can have unexpected consequences. Regression testing in software QA means testing the software after a development cycle to ensure that existing functionalities haven’t been adversely affected.

It definitely makes sense to test applications, do a website performance test, or do any other form of quality assurance testing after rebuilding the code of your digital product. The purpose is to make sure there are no bugs that have been accidentally introduced into the new version, and to guarantee that previously fixed bugs don’t cause new trouble.

Traditionally regression tests have been performed by the software quality assurance team after a development cycle. They normally perform regression testing as unit testing or functional testing.

Let’s take a look on those different types of software testing: While unit testing focuses on individual parts (units) of the software and secures that they are working as intended, functional testing puts emphasis on the functions or features of the digital product – not only on separate units.

How to Run a Regression Test

Commonly, QA testers re-run testing scenarios that were written when a bug appeared for the first time. By repeating this test after every release or iteration you can make sure that all old bugs remain fixed. 

This repetition can already be quite time-consuming after only a few releases and bug fixes. That’s why it can be useful to use automation testing tools for those kinds of repetitive tasks. 

However, manual regression tests are common as well. Unlike automation software in QA automation, real testers can add additional benefit. Also, setting up a test automation framework takes a lot of effort before it is finally running. This makes automated testing useful only if you have a lot of releases in a short amount of time.

Manual Regression Testing with the Crowd

If you don’t plan to invest in automation tools, but still need quick and reliable test results, Crowdtesting should work well for you. Software testers from all over the world test on real devices and real browsers. 

You can give testers structured test scripts and let them check precisely those functions you want a closer inspection of, or you can let them explore your digital product more freely – hoping to detect some bugs that might be new to you. 

Of course, you can also combine UI tests with structured system testing. Additionally, no matter which type of regression test you choose, you can opt to run tests regularly to always ensure that your latest release is still problem-free.


The Challenge: fixing errors shouldn’t lead to new bugs

Even small changes in the source code of your application, website or any other digital product can cause a domino effect of problems. Detecting those problems can be time-consuming and nerve-racking as they can seem completely unrelated to the changes made. Regression tests help you to not only make sure the fixed software part is working correctly now but also secures that all other functionalities still behave like intended.

Testing, finding bugs, fixing bugs and testing again – this is how your development lifecycle should ideally look like. This might sound plausible, of course, but most of the time this plan fails due to a lack of time and resources.

That’s why tools for test automation are often used for the sake of efficiency and thoroughness. In some cases though, manual testing is preferable, especially when considering the huge amount of effort required to create test cases for automated testing.

The Solution: Regression testing – manually with the Crowd

Let our Crowd check your digital product for bugs and malfunctions after a new release, a bug fix or other changes on the software code. Instead of investing hours in the development of automated software testing, you can start your Regression Test today. Our Crowd supports testing any digital product – regardless if it as a website, an app or an IoT-device.

Get ad-hoc access to the largest testing community of over 500,000 testers worldwide and also use their skill set for the creation of test cases. Our Crowd provides a huge amount of over 1,000,000 devices with a broad range of operating systems (OS) and versions. With their help, you can perform exploratory or structured regression tests under real-world conditions and repeat after each iteration or modifications in your software.

Depending on your requirements, this repetition can be performed by the same or an entirely new group of testers. Use our testing platform, the Nest, to monitor your entire test and export bugs to your own bug tracking software like JIRA or Redmine.


How does it look in practice?

30 testers, 20 different device and operating system combinations and 30 test cases – these were the basis for a structured regression test that was requested by a large scale mail-order company. The test subject was an online shop with responsive web design. In total, our testers revealed 160 bugs, of which 18 were rated as critical, such as problems with the checkout process or issues with payment.

Together with our experienced project manager, the client prioritised the ten most important test cases. After fixing the bugs found, the same 30 testers performed exactly those ten cases again. The procedure was repeated twice until there were no further critical bugs appearing.
