Regressziótesztelési

Regressziótesztelési, often translated as regression testing, is a type of software testing that verifies that recently implemented changes or bug fixes have not adversely affected existing functionality. The primary goal is to ensure that the software still works as expected after modifications.

This testing is typically performed after code changes, such as adding new features, fixing bugs, or refactoring existing code. When new code is introduced, there's a risk that it might unintentionally break previously working parts of the application. Regression testing aims to catch these unintended side effects.

The process usually involves re-executing a subset of previously executed test cases. These test cases are chosen to cover the critical functionalities of the software. The set of test cases can be manually executed or, more commonly, automated to save time and resources. Automation is particularly beneficial for regression testing due to its repetitive nature.

Key benefits of regression testing include improved software quality, reduced risk of introducing new defects, and increased confidence in software releases. By systematically re-testing existing functionality, teams can ensure stability and reliability. It's a crucial part of the software development lifecycle, contributing to a more robust and dependable product.
