Which statement is NOT true about testing a class interface $($i$.$e$.,$ unit testing$)$ using black box methods?

Group of answer choices

Given a method of a class under test, the current state of both the global variables of the class and the method$$s parameters will be part of the input for testing the method.

When testing a class interface, usually, we can unit test each method of the class separately.

We can use stub classes$/$methods$,$ which act exactly in the same way as how the corresponding real classes$/$methods work, to make the class independent of other classes$/$methods during unit testing on the class.

Given a method of a class under test, both the new state of the global variables of the class and the exceptions of the method will be part of the input for testing the method.
