Progression testing helps identify defects early in the development process, allowing for quicker and more efficient fixes. If you want to employ modern software development and testing techniques, you have to move on from simple unit testing by developers and implement regression testing in your quality assurance (QA) organization. To obtain results with high content fidelity, a comprehensive objective function is proposed to simultaneously encourage the boundary rectangular, mesh shape-preserving, and content perceptually natural. In corrective regression testing, testers focus on the sections of code that have undergone changes, ensuring that the corrections do not spawn new bugs. Regression testing is performed to check the stability of all areas impacted by any functionality change or code change. The focus of exploratory testing is more on testing as a “thinking” activity.
