You probably don't need to create a contract for every new product, as this would be expensive in terms of gas consumption.

struct Product {
string name;
uint256 price;
}
Product[] public products;

I updated your code with examples of creating array of contracts, passing data and reading that:
pragma solidity ^0.6.0;
contract Item {
uint public blabla1;
uint public blabla2;

blabla1 = _blabla1;
blabla2 = _blabla2;
}

I still dont know what is causing the problem, but I found a work around. I made a bash script that tests each file individually, so that the truffle environment hard resets each time. Here it is.

truffle test "$filename" --compile-none
done
