What is regression testing?

Regression testing is a critical quality assurance process designed to ensure that new code changes, updates, or patches do not adversely affect existing features. In complex enterprise web applications, traditional testing often struggles with fragile selectors and the overhead of maintaining scripts for multi-role workflows. By systematically re-running a suite of tests after every modification, teams can verify that software remains stable and that new functionality does not introduce regressions into previously working areas of the application. Argus QA evolves this process by introducing autonomous AI computer-use agents that interact with applications like a human would. Instead of relying on static coordinates, these agents observe screenshots, reason through their next steps, and execute actions based on versioned YAML objectives. This approach allows for the validation of long, frequently changing, and multi-role business processes—such as those involving creators, approvers, and suppliers—while maintaining a strict human-in-the-loop requirement for defect reporting to ensure total accuracy.
