What is Regression Testing? Explained with Test Cases, Tools, and Methods What is regression testing? Definition, test cases, tools and methods

To provide companies with agile maintenance, at PFLB we run continuous system monitoring of nightly and weekly builds. Automation gives you a competitive advantage only if you utilize it properly. So first, you need to identify which test cases you can automate and those that don’t have a scope of automation. Then, automating suitable test cases will increase your productivity and save precious time.

Categorization of test cases enables new testers to quickly grasp the testing approach and offer robust support in accelerating the test execution process. Prioritizing test cases also allows teams to make the process simpler and easier to execute, thereby streamlining the testing process and outcomes. This approach is normally used when the development team struggles to define the number of changes made or the impact of these modifications.

Regression testing definition

Though we have discussed this working method in the “Test Case Selection” part, we must mention that this type of regression testing is highly efficient in terms of time and resource consumption. In this method, you just have to focus on the specific old test cases that you have selected for their direct relevance to your test objectives. Hence, the exemption of testing the complete system and focusing on the necessary part only saves you a lot of time, effort, and resources.

Essentially in this step the team formulates a step-by-step plan and prepares the right testing system to perform regression testing. It is necessary to also discard obsolete test cases or test suites for effective test management in the future. In other words, if your product undergoes frequent modification, regression testing will be the filter that ensures quality as the product is improved.

Progressive regression testing:

So, let us put light on the facts that can help you differentiate between these two widely used forms of testing. If you’re here, you definitely decided to create a dating app and look for opportunities to launch a unicorn at a fraction… Software development projects are a journey with many potential roadblocks that can arise along the way.

If you’re running a complete regression test, then automated testing can do it quickly without the need to prioritize test cases. A defined structure and set of guidelines for automated test cases so that testers understand what they have to do and don’t waste time running ad-hoc tests. For example, during regression testing, testers will use the test cases from functional testing. Similar to https://globalcloudteam.com/ selective regression testing, partial regression testing is used when a new piece of code is merged with existing code. Keep the test case file updated with new scenarios and perform regression testing based on that file. Before developing a test automation framework, QA professionals complete integration tasks to ensure that they can focus solely on running the script for regression testing.

Regression test selection

Instead, they might select the one that best suits the scenario, or they might use a mix — whatever it takes to verify that the software doesn’t have any bugs while ensuring an efficient process. When two pieces of software developed by different teams are integrated, new problems and incompatibilities could pop up. The regression testing process ensures the two software pieces work well together without any what is regression testing major issues. Some of the most common regressions that need testing include functionalities such as login, search, and checkout. To detect these regressions, you can use different methods such as checking the application’s output against expected results, performing functional tests, and using automated tools such as HeadSpin. This approach implies that all the tests of the system should be re-executed.

Sprint-level regression testing – This type of test emphasizes on executing the test cases that have emerged only after the last release. General functional regression – a range of broad tests across all areas of the app aimed at ensuring that recent changes have not resulted in code destabilization. The tests of the basic functionality of the product and pre-system acceptance are the first a QA specialist should concentrate on, as they provide the most value both for users and engineers. In the long run, you’ll be able to reuse such scripts for your next project – it improves the efficiency of software maintenance and creates a set of standards within the team.

Bug regression – a tester checks if a specific bug that has allegedly been fixed was in fact eliminated. It’s always helpful for a tester to determine which cases are the most relevant for the program and focus on executing them as a first priority. Here’s a simple framework you can follow while grading the value of test cases. Regression testing is best done by developing a plan early in the development process and sticking to it until the product is released. Since we have seen the Regression Testing Examples, here’s an overview of the Regression Testing Process. Furthermore, automation is an important aspect of regression test since it allows you to make the most of your test case capabilities.

You should compare and track their business impact on different platforms, and based on those evaluations; you should set high, medium, and low priority to various test scenarios. This would help you understand, differentiate, and identify multiple roadblocks and conduct effective testing based on the requirements. With the help of this tool, testers can write a test case that is easy to read and understand.

Regression Testing Types

In the corporate world, regression testing has traditionally been performed by a software quality assurance team after the development team has completed work. Changes that may require regression testing include bug fixes, software enhancements, configuration changes, and even substitution of electronic components. As regression test suites tend to grow with each found defect, test automation is frequently involved. The evident exception is the GUIs regression testing, which normally must be executed manually. Sometimes a change impact analysis is performed to determine an appropriate subset of tests (non-regression analysis).

• But you’ll want to give a complete check if the app hasn’t been tested in a while.
• While regression testing may be integral to the quality assurance process, it comes with its fair share of challenges.
• Katalon Studio is an end-to-end automation tool that enables functional and regression test, making these procedures quick and simple for testers to perform.
• This practice is to double-check on whether the current code functions fine, and whether we can reuse the existing test cases or not.
• The less automated these tests are, the less they are executed and the later they are tested, which, in addition to going against the principle of ‘test early’, leads to losses of money and motivation.
• After this process, they forward the requirement test bundle to the automation department.

Regional Regression testing

Make detailed test case scenarios for regressing the testing approach. Based on the level of development and product stability, a suitable approach for test plan creation can be deployed. Use a structured approach for managing regression risks, such as a risk registry or risk management plan; this will help ensure that all threats are captured and tracked. Measure or change the scale of the upgrade to determine how likely it would affect the application. Automated & manual testing made easy through data science insights. We use a large number of tools to run test cases – the list includes TestLink, JIRA, HP ALM, Microsoft TFS, and many more.
