RETESTING

Retesting aims to improve the quality and reliability of the product. It involves repeating tests on software elements that previously exhibited unintended deviations from expected results.

THERE ARE SEVERAL KEY REASONS WHY RETESTING IS ESSENTIAL IN THE SOFTWARE DEVELOPMENT CYCLE:

Verification of bug fixes:

Retesting verifies whether errors identified in previous tests have actually been resolved. After coding corrections, there's always a risk that other parts of the code could have been inadvertently affected. Thus, it's necessary to retest to ensure fixes haven't negatively impacted other software components.

Assessing the impact of implemented fixes:

Retesting helps evaluate whether recent changes introduced any new issues. Occasionally, fixing one bug can lead to the emergence of secondary bugs. Therefore, it's essential to monitor these changes and evaluate their overall impact on the software's functionality.

Product improvement:

The retesting process aims at progressively refining the product. Each round of retesting helps eliminate bugs and enhance the overall quality of the software. It's a crucial step to ensure the product meets user expectations and aligns with design objectives.

Retesting forms an integral part of the software testing process, facilitating continuous product improvement. It maintains high quality and reliability, which is critically important in today’s digital world. It’s vital to recognize that testing is not merely about finding defects but also about ensuring quality and user satisfaction.
