I've written a test that involves returning the token balance that the contract itself holds. In the contract source file I would access the balance using the function
getBalanceOf(this). However, when I include
instance.getBalanceOf(this) in my JS tests, I get a
new BigNumber() is not a number error.
I've narrowed it down to my tests not having access to the deployed contract's address. I know you can access it in Solidity tests using the DeployedAddresses.sol library, but is there any way to do it in JS tests?
