Why is System Screening Important?

System screening assists us ensure that for any function and provided set of systems, we can establish if the system is returning the correct worths. It likewise ensures us that if void input is offered, the code can determine and deal with the failures.

Let’s see the outcome of the tests.

As we can see from the image, we now have an assertion.
