What does the term "retest" refer to in testing and evaluation?

The term "retest" specifically refers to the process of conducting a test again after corrections have been made to identify and verify improvements or to confirm the reliability of results. This often occurs after issues or deficiencies were identified during the initial testing phase, and modifications have been implemented to address these issues. The goal of a retest is to ensure that the changes made have resulted in the desired outcomes and that the system or product now meets the required specifications or standards.

In contrast, preparing new tests from scratch involves creating entirely different assessments, which does not align with the concept of retesting. Similarly, assessing only partial test outcomes would imply a focus on a subset rather than a full retest, which would not provide comprehensive verification of the fixed issues. Lastly, implementing changes without testing runs counter to the principle of retesting, as it bypasses the necessary validation process to assess whether the changes have been effectively realized.
