Testing frameworks not working on live networks

[lyh970817]

Version of Hardhat

2.13.0

What happened?

I can use the expect statement in the following manner when testing with hardhat local network:

expect(await goodbye.airnode(), "Airnode address").to.not.equal(ethers.constants.AddressZero);

This, however, does not work when the contract is deployed on a live network (npx hardhat test --network mumbai. It appears to forever hangs when the statement previous to the expect statement finishes running.

Minimal reproduction steps

Add config for a live network in hardhat.config.js, deploy a smart contract on the live network with any public variable and use an expect statement similar to the following in a file in the test folder:

expect(await CONTRACT.PUBLIC_VARIABLE(), "Public variable").to.not.equal(ethers.constants.AddressZero);

Hi @lyh970817, the only reason that statement could hang is if the goodbye.airnode() is hanging. That might be related to the node provider you are connecting to or something else, but it's unlikely to be related to Hardhat. Notice that you are using a plain .to.equal comparison, so this doesn't even involve our plugins.

Happy to re-open if you can provide specific steps that show that something is not working on our side.
