Final answer:
Advantages and disadvantages of testers being unfamiliar with the product or application they are testing.
Step-by-step explanation:
There are both advantages and disadvantages to having testers who are unfamiliar with the product or application they are testing. One advantage is that inexperienced testers can approach testing with fresh eyes and make observations or ask questions that more experienced testers might overlook. This can help uncover potential issues or usability concerns that were not previously identified. However, the disadvantage is that unfamiliarity with the product or application can lead to assumptions and oversights in the testing process, which can result in missed bugs or incomplete testing.
