While experience-based testing can be very effective, it does have some drawbacks.

Experience-based testing is a technique that relies on the tester’s intuition, skills, and past experiences to create test scenarios. However, this approach makes it challenging to measure and assess the test coverage, as there is no clear criteria or method to determine which areas of the software have been tested and which have not. This can lead to gaps in the testing process and potential risks of missing defects1
