What Is Regression Testing | How To Build Regression Testing Suite

App developers are constantly trying to improve their software to meet the growing demands of customers and to surpass the competition. Therefore they need to release software updates and changes almost every month across a number of features in the app. Thus, it is imperative that developers re-engineer or modify existing software, add more elements, technologies or functions where the updates are required. Also, they should be aware that even a minute fix made in the application code can have unintended consequences in the whole solution. It may disrupt existing features or perform inefficient performance on some devices.

To make sure that there are no such disruptions and that the changes made to the applications are updated properly, regression tests are performed on the software solutions. The regression test ensures that both large and small changes are updated and added efficiently without disrupting any of the existing functions of the app. The purpose of regression tests is to proactively identify errors that may have been accidentally inserted into a new structure and to make sure that previously deleted errors do not reappear. Such tests can be performed manually in small projects, but in most cases, restoring a test package each time an update is made is time consuming and difficult to consider, so an automatic testing tool is usually needed.

What is a software regression test?

Some QA teams throughout the software development process try to avoid regular regression tests and tend to test the essential functions only once. They choose to test modules once to ensure it works and if so they continue with the assumption that it will always work properly. To many of us, this may seem like the right approach because once the test is complete and repairs are made, the module should work efficiently in the future. But this is not always the case; Even small, seemingly insignificant changes in the source code of an application can have serious consequences for other modules in the application. And although this module has been tested and verified initially, it may still break or receive other responses from completely unrelated new changes. Therefore, when QA teams run regression tests, they check that even the smallest changes in the app will not affect other areas in the app and it will work efficiently just as required.

How to build an effective regression testing package

Here are four steps you can take to begin the process of preparation for mediation.

1. Prioritize your regression tests

Each application has a set of basic functions and other functions that are not so important or less necessary. When building a regression testing package, the initial process should be evaluation and identification of critical or high-priority tests for implementation. The basic functions or the main purpose of the application must be considered a high priority and the other functions should be a lower priority. The regression tests for these critical functions will evaluate everything from back engines, application programming interfaces (APIs), and database connections or performance.

2. Construction of smoke tests

When you apply your critical and high priority tests in a regression package, give it a “smoke test package” and test it on a daily basis or after each and every construction. Complete the smoke tests before starting any other test to avoid random shutdowns. Testers can also automate smoke testing, with Applause Codeless Automation (ACA) or script testing, to speed up the release rate by allowing anyone to create testing automation scripts. Therefore, if testers apply the tests in a simple way, i.e. with one or two verification points, it makes the analysis of failures less complicated and simple. Also, remember not to test any function in a smoke test; Simply include the basic components of the application, such as core functions. The smoke tests can then damage errors in these areas and correct them or notify the QA teams.

Make a manual effort

Next, build a test suite for these core functions or for the critical purpose of your application. This is because core functions are often not independent and often contain complex interactions with other modules of the application. Due to the complexity of such interactions, it will be difficult for an automated testing tool to test and ensure its effectiveness. By implementing manual regression tests, QA teams will be able to include exploratory tests that the automation tools will not cover. There are testing service providers that combine both manual testing and automation testing in product or software testing. At ThinkPalm, we also leverage this combination of manual testing and automation to cover end-to-end testing or system workflows that are long and complex.

4. Check the integrations

Build a regression testing package that effectively checks all of your backend messaging engines, application programming interface (API) connections and data feeds as well. Different applications will have a different integrated process that takes place in a background that is not visible to the end user. Sometimes, building a regression testing package for these types of functions can be tedious and will often require the assistance of a developer or IT, but it’s well worth the effort.

5. Check the performance of the app

With each new change in the app feature or the source code change, the user experience changes and so does the app performance. Sometimes, when new features are added, the application tends to be much slower than it was initially. All this can significantly affect the efficiency of the application. If the app is not particularly fast, responsive and efficient, users will lose confidence in it. Therefore, while you are building regression packages, you need to make sure that it is responsible for performance testing. Testers must always develop a performance regression package with a performance test tool, framework, or simple manual test that tests low-performance areas.
