Lesson 6: ValueError: insufficient funds for gas * price + value when testing bad_actor try to use withdraw function

[JeremieWU23]

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:

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?

When I change my test_only_owner_can_withdraw() function by letting bad_actor = accounts[1] instead of accounts.add(), it can give the same Error brownie.exceptions.VirtualMachineError: revert in the video:

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()
    bad_actor = accounts[1]
    print(bad_actor.balance())
    fund_me.withdraw({"from": bad_actor})

Did the accounts.add() method change after the video was uploaded, now the balance of the account will be set to 0?

I'd be very appreciative if somebody can give me an answer!!!

Oh that is odd... Could you make an issue on the brownie repo and ask on stack exchange eth?

Then maybe post in the python discord: https://discord.gg/YGzGZEfSBc
