What is Retesting?

Retesting in software testing involves verifying a specific part of a software application after a defect has been fixed to ensure the issue is resolved and the software functions as expected. Unlike regression testing, which assesses the whole system for any indirect impacts from changes, retesting focuses narrowly on the fixed bug, using the same test steps as before. Retesting can be done manually, which allows for human insight and flexibility, or through automation, which saves time and reduces error for repetitive tasks. Tools like testRigor facilitate automated retesting by allowing test cases to be written in simple language, even as system elements change, and integrate easily into CI/CD pipelines for continuous testing. Effective retesting involves understanding the fix, prioritizing high-impact issues, ensuring the fix is verified in the appropriate environment, and automating tests where possible to enhance efficiency and accuracy.
