[Ethereum] How to mock the time for solidity tests

I never used it but there is this library by @pipermerriam called ethereum-datetime, so you could call his contract to get what you want

I'm relatively new to this but from all the tutorials I've seen with respect truffle and unit testing, they all tend to use the Mocha and Chai testing framework. I would recommend looking into those two libraries. There's lots of tutorials on them online.

Take a look at this tutorial from DAPP University. He does a pretty good explanation of how to use the libraries for testing. (Unit testing starts around the 47 minute mark)

There are several out there so feel free to use a different one. In all the tutorials I've watched I can't recall ever seeing someone put a unit test directly into a solidity smart contract. Normally they're either a javascript file or python file that interacts with the smart contract.

By moving your test code out of solidity and into a .js or .py file you should greatly reduce your gas fees. (I imagine this would help with your memory issues too, but like I said I'm pretty new to this and have never seen someone try to perform a unit test within solidity.)
