Lesson 6: ValueError: insufficient funds for gas * price + value when testing bad_actor try to use withdraw function #109
Description
In the video 5:53:30, try to use withdraw function with a bad_actor and get an browning.exceptions.VirtualMachineError: revert. But when I use brownie test -k test_only_owner_can_withdraw to test, the console gives this error message:

Terminating local RPC client...
Here is my test_only_owner_can_withdraw() function:
def test_only_owner_can_withdraw():
if network.show_active() not in LOCAL_BLOCKCHAIN_ENVIRONMENTS:
pytest.skip("only for local testing")
fund_me = deploy_fund_me()
bad_actor = accounts.add()
print(bad_actor.balance())
fund_me.withdraw({"from": bad_actor})
It seems that the account bad_actor does not have enough balance to send a tx, the print its balance is 0. And then raise this error. Why in the video there is not this error?
