Calling overridden functions with Hardhat

Often when we write tests for our smart contract functions we will use syntax:

await name_of_contract.name_of_function(arg1, arg2, arg3)

Where name_of_contract is the return value of smart contract deployment. Where name_of_function is an example function from smart contract we are testing.

Now, if we want to call the safeTransferFrom function which is often marked as override & virtual in our smart contract (or any similar function) then we will need to use totally different syntax or error safeTransferFrom is not a function will be thrown.

That is why to avoid this problem entarily for any override & virtual we should use syntax:

await name_of_contract["safeTRansferFrom(address,address,uint256)"](
owner.address,
bob.address,
tokenId
);

Now safeTransferFrom will be seen by Hardhat and you will get expected return values.
