When should we stop testing?
Ans. Testing (both manual and automated) can be stopped when one or more of the following conditions are met-
1. After test case execution – The testing phase can be stopped when one
complete cycle of test cases is executed after the last known bug fix with the agreed-upon value of pass-percentage.
2. Once the testing deadline is met – Testing can be stopped after deadlines get met with no high priority issues left in the system.
3. Based on Mean Time Between Failure (MTBF) – MTBF is the time interval between two inherent failures. Based on stakeholder’s decisions, if the MTBF is quite large, one can stop the testing phase.
4. Based on code coverage value – The testing phase can be stopped when the automated code coverage reaches a specific threshold value with sufficient pass-percentage and no critical bug.
