Error on Terminating local RPC client... Lesson 5

[sanspeur33]

Finishing up lesson 5 and started getting this error on the client termination after the test is successful. No errors when just running deploy.py
Python 3.9.6
Brownie v1.17.2 - Python development framework for Ethereum
pipx 0.16.4
vscode

my code:

from brownie import SimpleStorage, accounts



def test_deploy():
    # arrange
    account = accounts[0]
    # act
    simple_storage = SimpleStorage.deploy({"from": account})
    starting_value = simple_storage.retrieve()
    expected = 0
    # assert
    assert starting_value == expected


def test_updating_Storage():
    # arrange
    account = accounts[0]
    simple_storage = SimpleStorage.deploy({"from": account})
    # act
    expected = 15
    starting_value = simple_storage.store(expected, {"from": account})

    # assert
    assert expected == simple_storage.retrieve()

results:

Hello @sanspeur33 does this helps you?

[sanspeur33]

Worked. Put this in from looking at the deploy.py. Thank you.

def test_updating_Storage():
    # arrange
    account = accounts[0]
    simple_storage = SimpleStorage.deploy({"from": account})
    # act
    expected = 15
    **transaction = simple_storage.store(expected, {"from": account})
    transaction.wait(1)**
    # assert
    assert 15 == simple_storage.retrieve()

I'm glad it worked for you, fell free to make any other questions.
