understand regression testing: 3 things to know about

Regression testing is an integral part of the app testing suite. It uses black-box testing techniques. Regression tests help verify that any software code change does not impact its existing functionality and continues to deliver flawless performance. Hence, it lets the QA determine that the new functionality, bug fixes, or changes in the existing feature do not cause the app to falter. It ensures that the app's working processes or modules are left unharmed.

Regression testing makes use of test cases that you have used already and can re-execute them to ensure that the product continues to work the same way as before. These tests can focus on a single unit of code, interacting code units, or the entire codebase. The QA must know how to perform regression testing and include it suitably in the test module to generate valuable results. The testers must test on real devices online to ensure that the products deliver seamless performance in real-world scenarios for enhanced user experience.

Here are a few essential things you should know about regression testing.

When To Run Regression Tests?

-When you introduce new functionality in your software, you need to run regression tests. The introduction of new codes required the QA to test its compatibility with the existing code and find any possible issues in the product.

-If you revise the app's existing functionality and exclude or edit any of its features to meet your needs, you need to incorporate regression tests. It helps to test if the new changes are affecting the app's functionality.

-If new integrations take place with other products, running regression tests is vital to validate such integrations.

Importance Of Regression Tests

-Software updates take place constantly to meet the ever-evolving needs of consumers. It makes the app easier to navigate and improves its features. Regression tests help to ensure that the changes and updates bode well for the app and enable it to perform as expected.

-Before you release the app in the market, running regression tests can help you to do away with errors and ensure that it does not suffer setbacks after its release.

-Regression tests determine that after you place the necessary changes, the product continues to work as it used to and with more efficiency due to the upgrades.

-Regression software testing practice helps in preventing software quality degradation with the growth of functionality. It allows you to minimize the probability of persisting operational errors.

Best Practices in Regression Testing

-Establish a schedule for regression testing to maintain it seamlessly across the software development life cycle.

-Use a test management tool to track the tests. It can help you make efficient decisions about test cases for proper execution. It enables you to identify changes and improvements in test cases and analyze the regression testing outcomes.

-Evaluate test prioritization to analyze the feasibility of the tests. Regression testing is complex if the app's scope is enormous and if the system requires continuous increments or patches.

To Conclude:

These are a few crucial aspects of regression testing. Select the regressions tests very carefully to cover maximum functionality within minimum test case sets. It will help you ensure that the changes do not affect the software's functional aspects.
