Automated Regression Testing Services

Regression testing is a type of testing that 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.

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 more important functionalities, functionalities that fail frequently, complex test cases, test cases that cover the recent code changes, etc.

Why Automated Regression Testing Services?

1
Users are demanding rapid changes to applications as their needs are more dynamic than ever before. Within today’s fast-paced digital landscape, database changes, operating system updates, feature enhancements, integrations, patches and other critical elements require CI and CD methodologies. This requires robust Continuous Testing (CT) practices to ensure seamless software delivery.

Regression testing is a critical CT practice that involves re-running functional and non-functional tests to ensure software changes do not impact performance. Companies need robust test automation services for automating repetitive tasks and streamlining regression testing processes. This allows for comprehensive coverage, faster feedback loops and an improvement in the quality of the software.

Our software backtesting approach reduces reoccurrence risk and minimises the likelihood of new problems. This reduces IT project support costs and improves quality and speed. As a result, clients receive complete progress reports and real, practical QA results. By using advanced problem solving tools and suites, we ensure the efficiency and productivity of the entire development process and meet 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 to save time and costs.

We understand your priorities, basic functional cases list, and we can automate the regression suite using 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.

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 e-commerce 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 e-commerce website, integration testing comes into play.
This testing ensures that combining two systems does not break anything and that the flow functions 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 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.
