One model that could be performed by a computer is running a car safety test.
One benefit would be the price reduction of testing the safety mechanisms of the car with all the necessary impacts that need to be applied to them. One drawback is that if any line of code of the car safety characteristics is wrong. It won't be representative.
All right, computer modeling is a very useful tool for developers and testers because they can help the developmental process of anything. In our case we chose safety car mechanisms, however, they can apply to almost anything. One benefit would be that the testers would safe on research and development expenses by pursuing computer model tests, instead of a test in real life because they would damage cars. However, one drawback is that they could be wrong in a line of code and have an unrealistic test.
