Lesson 7 test_lottery_unit error

[brownandrew1390]

I have been getting this error when trying to run test_get_entrance_fee in test_lottery_unit

    def test_get_entrance_fee():
        if network.show_active() not in LOCAL_BLOCKCHAIN_ENVIRONMENTS:
            pytest.skip()
        # Arrange
        lottery = deploy_lottery()
        # Act
        # 4500 eth/usd
        # usdEntryFee is $50
        # 4500/1 == 50/x == 0.011
        expected_entrance_fee = Web3.toWei(0.011, "ether")
>       entrance_fee = lottery.getEntranceFee()
E       AttributeError: 'NoneType' object has no attribute 'getEntranceFee'

tests\test_lottery_unit.py:17: AttributeError

Here is my corresponding deploy_lottery.py script. Let me know if I am missing something here.

from brownie import Lottery, config, network
import time

def deploy_lottery():
    account = get_account()
    lottery = Lottery.deploy(
        get_contract("eth_usd_price_feed").address,
        get_contract("vrf_coordinator").address,
        get_contract("link_token").address,
        config["networks"][network.show_active()]["fee"],
        config["networks"][network.show_active()]["keyhash"],
        {"from": account},
        publish_source=config["networks"][network.show_active()].get("verify", False),
        
    )
    print("Deployed lottery!")

def start_lottery():
    account = get_account()
    lottery = Lottery[-1]
    starting_tx = lottery.startLottery({"from": account})
    starting_tx.wait(1)
    print("The lottery is started!")

def enter_lottery():
    account = get_account()
    lottery = Lottery[-1]
    value = lottery.getEntranceFee() + 100000000
    tx = lottery.enter({"from": account, "value": value})
    tx.wait(1)
    print("You entered the lottery!")

def end_lottery():
    account = get_account()
    lottery = Lottery[-1]
    # fund the contract with LINK
    tx = fund_with_link(lottery.address)
    tx.wait(1)
    # then end the lottery
    ending_tx = lottery.endLottery({"from": account})
    ending_tx.wait(1)
    time.sleep(60)
    print(f"{lottery.recentWinner()} is the new winner!")


def main():
    deploy_lottery()
    start_lottery()
    enter_lottery()
    end_lottery()

Hey @brownandrew1390 just add , return lottery in your deploy_lottery() method located in deploy_lottery.py.
Its showing AttributeError: 'NoneType' object has no attribute 'getEntranceFee' because 'lottery' in test_lottery_unit.py hasnt been initialized
