At Zappletech, we do regression testing for each code changes or functionality changes. We’re creating and automating regression test suites based on the business requirements, priority modules, important features, etc and execute them during every test cycle and ensure that the system is working as expected. We prioritize the test cases for the regression test suite based on the functionalities that are more important, functionalities that fail frequently, complex test cases, test cases that cover the recent code changes, etc.

Why Automated Regression Testing Services?

Users demand rapid changes to applications as their needs are more dynamic than ever. Modifications in the database & operating system updates, functionality enhancements, integrations, patches, etc. require Continuous Integration (CI) and Continuous Deployment (CD). This requires Continuous Testing (CT) practices being in place.
Regression testing is a CT practice that mandates re-running of functional & non-functional tests. By making any changes, the software performs as it did before. For the regression test to function effectively, it is important for enterprises to implement robust test automation services in place.
Our approach to software backtesting mitigates the risk of recurrence and minimizes the chances of new problems. This reduces IT project support costs and improves the quality and speed of deployment. As a result, a client receives a complete set of progress reports and actual and practical QA results. By applying advanced tools and suites for problem-solving, we guarantee the efficiency and productivity of the entire development process and adherence to deadlines.

Our Automation Approach In Regression

Regression testing requires the execution of a set of test cases for every test cycle, which is a time-consuming and tedious process. So, Zappletech focuses on automating the regression testing efforts that would save time and costs.

We understand your priorities, basic functional cases list, and we can automate the regression suite using an open-source tools. We run a full regression suite to ensure complete functionality coverage after any server patches, code changes, and database upgrades of your code.

Comprehensive strategy:
A mixture of API testing, manual testing, automated testing, UI testing, & unit testing
Detailed traceability matrix:
Outlines of the requirements vs. test cases
Dependency analysis:
Performed between test cases and requirements
Change reports:
Issues between the current release and previous release
regression test pack
Risk-based analysis:
Pareto analysis, FMEA, Output from code coverage report, etc.
Continuous pruning:
Regression tests packs are continuously pruned by removing the test cases that are no longer needed & inserting additional ones.

What are the distinctions between regression, integration, and unit testing?

Let’s use an example to demonstrate the differences between the three. Assume you’re creating an ecommerce site. To test a significant portion of code or module responsible for inventory management, you’ll need to use unit testing. When you need to add a third-party payment system to your ecommerce website, integration testing comes into play. This testing ensures that combining two systems does not break anything and that the flow is functioning properly. Finally, you run regression tests to determine if your new features, such as an inventory management module and a payment system, have broken anything else on your site. Regression testing entails re-testing functionality after each change. Software developers perform unit testing. Both developers and testers perform integration testing.

Manual or automated regression testing?

Automating frequently repeated test cases is always a good idea, especially in large projects. Manual testing may be the most efficient option if you have a tiny application with fast changing features.

When should regression testing be carried out?

The following are some of the most common regression testing scenarios:
– Running test cases with a lot of defects
– Verifying basic product functionalities – Testing user-facing functionality
– Putting integration test cases to the test

What role does regression testing play in the development of high-quality software?

The likelihood of software issues grows with each new change, bug correction, system update, or new feature implementation. Bugs might go into production unnoticed unless regression testing is performed. Regression testing ensures that each release is of high quality. It is the “stepchild” of agile testing, and it is required for agile teams to consistently deliver high-quality software.

Regression testing in software engineering is a type of QA testing used to verify if new changes in the codebase didn’t affect the existing functionality of the application.

With every new alteration, bug fix, a system update, or a new feature implementation, the probability of software issues increases. Unless you do regression testing, you can miss the bugs on production. Regression automation testing helps you maintain the quality of every release. It is the “stepchild” of regression testing, critical to enable agile teams to deliver quality software over and over again

Below are a few most common scenarios for regression testing:
– Carrying out test cases with frequent defects
– Testing user-facing functionality
– Verifying core product features
– Testing integration test cases

Regression testing is perfect for test automation since it is so repetitive. Automation of regression testing is, in fact, a must for anything other than a modest project.

The functionality of new programming code is evaluated.
Ensures that new coding does not conflict with current coding.
After installing software updates, ensures that there are no faults or issues.
Allows existing software to be retested after changes to the application.

Let’s explain the difference between the three using an example. Imagine you’re building an ecommerce website. You need to do Unit testing to test a large chunk of code or module responsible for inventory management. Integration testing comes into play when you need to add a third-party payment system to your ecommerce website. This testing helps you make sure that integrating two systems doesn’t break anything and the flow is working as intended. At last, you are making regression testing to see if your newly added features such as an inventory management module and a payment system didn’t break anything else on your website. Regression testing is about re-testing the functionality every time you implement changes.
Unit testing is done by software developers. Integration testing is done by both developers and testers. And regression testing is performed by testers.

We always recommend automating frequently repeated test cases, especially at large projects. If you have a small application with rapidly-evolving features, manual testing may be your most efficient approach.

There are three aspects to consider when adopting a regression test automation approach: process, technology, and responsibilities.
