• In some cases it may be necessary to write part of the exploit in the setUp() function, due to the peculiarities of processing the SELFDESTRUCT command in Foundry
• Some tasks require fork testing (--fork-url)
• There are two roles in BaseTest.t.sol, sometimes it is required to send transactions from player, you cannot send transactions from owner
