8 Tips for Selecting Test Cases for Regression Testing



Imagine a scenario where your customers view that a nasty bug in your application the day a significant release was rolled outside. You had been raving about the newest upgrade but the insect currently blocks the principal work flow.

The update didn't mount upto your business's goodwill as it will have. Regression Testing is put in position simply to prevent such conditions.

Regression testing could be understood to be analyzing done to verify whether the code varies at a software/app have any kind of affect the existing functionality of the product or service.

It means when any formerly designed functionality of an software/app is broken, it's recorded before the shift is moved to production.

Take a look at a thorough guide on regression testing.

If not properly planned, regression testing can easily be overwhelming. To keep regression testing test cases manageable and effective, it is crucial to be careful when selecting the corresponding test cases.

Here we present for you several tips for selecting regression testing evaluation cases.

A pro-tip for you before you get started picking out a regression test cases will be to ensure the regression test package is uptodate and most of obsolete test cases are removed.

1. Select test instances for Regression testing where you will find code modifications or practical modifications

Testers should first concentrate on all those test cases wherever you can find changes in code/functionality of the application form. You will find higher likelihood of encountering problems in these spots. In the test case documentation, maintain the historical past of functionality changes in order to detect test cases which may be utilised from the regression suite later.

2. Select test instances that map into the organization prerequisites

It needs to be ensured that the functionality of the application form is working fine in accordance with the software requirements specified by the client.

3. Tester has to select the test cases in the areas where you can find ordinary bugs or flaws.

There might be some areas from the applications which often fail even with a small programming shift. There are more likelihood to getting multiple issues in these spots.

4. Select test instances for Regression testing of those regions which are visible to the user There may be several modules in it.

Suppose in a few of those modules, the logo of this application form is erroneous. That's an issue.

The issue is lower in severity but has high priority by a user's point of view. The tester needs to choose the test cases at the places which are observable to the user.

5. Pick all integration test cases for Regression testing

Integration testing can be really a type of software testing by which individual applications modules are all combined and they are analyzed in several group. Suppose that there was just 1 application that has 2 modules which are incorporated in a way that module 2 uses data of module inch.

Currently, whenever there isn't any upgrade in the info of module 1, the information of module 2 doesn't get upgraded.

This could be caused by integration issues in the port that's perhaps not allowing data transfer from module 1 to module 2. Testers need to check for these kinds of integration issues. All such integration test cases have to be selected during the regression testing.

6. Select all Intricate test instances for Regression testing

Program testing is becoming complex day by day. Most of the time, on implementing complex test cases, the application has crashed or the performance gets affected. This can become a significant matter.

To check the complexity efficiently, testers should use unique procedures and methods to guarantee software quality. Testers need to be certain that all complex test cases are a part of the regression testing suite.

7. Select test cases based on priorities such as Regression testing

As time passes, the regression test package may come to be big and take a significant amount of time for execution. In such cases, to reduce the testing efforts and time, first select all of the test cases which are of high priority by an individual's /customer's point of view.

Be sure that these test cases are working fine followed by other test cases which are of moderate and low priorities whenever allows.

8. Select test cases for Regression testing based on criticality and effect of insect fixes

If the criticality and impact of bug fixes is not low, then the tester can select only the top priority test cases to its impacted functionalities.

In case the criticality and result of bug fixes is high, then a tester needs to choose all test cases out of high, medium and low priorities.

Regression testing vs. UAT: Know the difference?

Image
  Regression testing and User Acceptance Testing (UAT) play a key role in developing a quality product. Regression testing ensures that the functionality of the software product or application is working as per the expected requirements, despite changes being made in the code.  User Acceptance Testing is involved in ascertaining whether the product meets business and user-specific requirements. In this article, you will get to know what are the differences between regression testing and user acceptance testing. What is Regression testing Definition? It is a testing method that verifies the new changes made to the code do not alter or modify the existing functionalities. This testing method makes sure that the existing functionalities do not get altered or modified, despite changes being introduced in the code.  Whenever a code change happens during the software application development process, regression testing is performed. This testing method checks the overall fu...

Regression Test Automation: A Quickstart Guide

Image
  The strategic need to automate regression testing: In many business scenarios, cost and time constraints are faced by organizations due to high-end software development and testing activities. This is because the mobile/web applications need to be thoroughly tested before they are released. When software goes through many changes for a release, there is a possibility for regressions (bugs found in the previous working functionality) to occur. When the functionalities of a software product have regressions then it may scale up the development costs and affect the software release deadlines. For this purpose, regression testing is conducted. But, when regression testing is conducted manually by the team, it consumes a lot of time. Hence, there is a need to automate regression testing.  When regression test cases are automated, the tester's time is saved from checking for regressions that have occurred due to the updates and changes that have been made in the application. Those...

How To Write A Regression Test Plan: Best Practices & Checklist For Effective Regression Testing

Writing a regression test plan is crucial for ensuring the stability and reliability of software applications, especially when changes are introduced.  Here are some best practices and a checklist to guide you in creating an effective regression test plan: Best Practices: 1.     Understand the Application: Gain a deep understanding of the application, including its features, functionalities, and critical areas. This knowledge is essential for identifying key regression test scenarios. 2.     Prioritize Test Cases: Prioritize test cases based on criticality, business impact, and the likelihood of being affected by changes. This helps focus regression testing efforts on the most important areas. 3.     Automate Repetitive Tests: Identify repetitive and time-consuming test cases that can be automated. Automation helps in faster execution, allowing more time for exploratory testing and focusing on complex scenarios. 4. ...
