What is back to testing are its benefits Cite 2 circumstances when it can be used?

Back-to-testing (BTT) is a software testing technique used to re-execute failed test cases from a previous test cycle. It helps ensure that previously identified bugs have been fixed and that the software functions as expected.

Benefits of Back-to-Testing:

1. Efficient Defect Tracking: BTT allows testers to focus on re-testing specific components or functionalities where defects were previously found, thus reducing the overall testing effort.

2. Cost-Effective: By identifying and fixing bugs early in the development process, BTT can help reduce the cost of defect remediation later in the testing cycle or in production.

3. Improved Quality: BTT helps ensure that defects are thoroughly fixed and that the software meets its requirements, resulting in higher software quality.

Circumstances When Back-to-Testing can be Used:

1. Release Planning: BTT is commonly used when a new software release is planned, to ensure that all previously reported defects have been addressed before the release.

2. Defect Triage: BTT is also useful when a defect triage process is in place, where testers prioritize and re-test defects based on their severity or impact on the software.
