--> For example, the verbosity levels of the EVM are:
        - 2 (-vv): Print logs for all tests.
        - 3 (-vvv): Print execution traces for failing tests.
        - 4 (-vvvv): Print execution traces for all tests, and setup traces for failing tests.
        - 5 (-vvvvv): Print execution and setup traces for all tests, including storage changes.

--> makePersistant- Each fork (createFork) has its own independent storage, which is also replaced when another fork is selected (selectFork). 
    By default, only the test contract account and the caller are persistent across forks, which means that changes to the state of the test 
    contract (variables) are preserved when different forks are selected. This way data can be shared by storing it in the contract’s variables
