LESSON 12: What is user1 & why do we need to use it?

[DorianDaSilva]

Hi,

A simple question regarding the unit.test.js:

How come the test requires we declare user1 for it to run?

I initialliy declared user but test was returning a Invalid address or ENS name error but after changing it back ot user1 test runs properly.

I haven't seen user1 being used in any of the scripts or contracts.

Thank you!

user1 is declared in the hardhat config file in the namedAccounts json. Basically, the purpose of the unit tests is to ensure that all the possible actions/operations we want our contract to do, are being done properly. Some of those actions involve a user interacting with our contract and if we want to test those actions locally, we would simulate a user on our network specifically for this testing. So, user1 is just a simulated user declared purely for our testing purpose.

@DorianDaSilva : In your hardhat.config.js file, There will be user1 declared in your namedAccounts, Thats why it is working,
while user isn't.
You can add other users in there aswell means :
default : 0 is deployer, means account "0" in hardhat node is deployer,
default : 1 is user1 means account "1" in hardhat node is user1.

So, the point is you can add as many users as you like, But you have to add them in your namedAccounts in your hardhat.config.js file.

We make different users just for the helping purposes in our testing.

Hopefully it will clear your doubt!
