How to use MockContract when the contract is passed as an argument to a interface?

[PaulRBerg]

I love MockContract, but it can't be used when the mocked contract is used as an argument to a contract interface.

Foo myFoo = Foo(fooAddress);

When fooAddress is an instance of MockContract, my test fails with the following error:

Error: Transaction reverted: function call to a non-contract account

How can we use MockContract in this scenario?

Hi, I was able to bypass this issue by configuring my environment like this:

const { ethers, waffle } = require('hardhat');
const provider = waffle.provider;

Use it as the following for getting the wallets: const [owner, notOwner] = provider.getWallets();

On my project I have the same exact use case as you, ie: C3ProjectToken token = C3ProjectToken(tokenAddress);

and it works fine :)
