Regression automation testing

Regression testing is a type of testing which ensures that any change in the application code does not affect the old working code and its features. In software development, any change to the code regarding enhancements, bug fixes, or new functionality might accidentally lead to new errors or the recurrence of old defects. So, it is always important to ensure that the application is working fine even after the changes. Hence, regression testing is highly essential when there is a continuous change in the application. Any software after the changes should pass regression testing. If not, the application might fail in the live environment.

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?

1
Users demand rapid changes to applications as their needs are more dynamic than ever. Modifications in the database & operating system updates, deployment configurations, bug fixes, functionality enhancements, integrations, patches, interfaces, etc. require Continuous Integration (CI) and Continuous Deployment (CD). This requires Continuous Testing (CT) practices being in place.
2
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.
3
Zappletech’s systematic approach to Regression Testing ensures minimum disruption while keeping costs under control. Our Regression Testing suite guarantees that the new features or enhancements to the application do not cause any unintended impact to the existing quality of the applications. Our regression testing solutions ensure outcomes of these enhancements are as per the original plan. Our test teams fully understand and perform impact analysis of the changes that are made to the test environment and the applications.

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.

1
Comprehensive strategy:
A mixture of API testing, manual testing, automated testing, UI testing, & unit testing
2
Detailed traceability matrix:
Outlines of the requirements vs. test cases
3
Dependency analysis:
Performed between test cases and requirements
4
Change reports:
Issues between the current release and previous release

Frequently asked questions

We gave answers to common questions related to Agile QA outsourcing. If your question isn’t covered here, please send it to us via email. We’re always happy to help you.

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

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.
