I have this code:
Token.sol
pragma solidity ^0.4.8;
contract Token {
/* The amount of tokens a person will get for 1 ETH */
uint256 public exchangeRate;
/* The name of the token */
string public name;
/* The address which controls the token */
address public owner;
/* The symbol of the token */
string public symbol;
/* The balances of all registered addresses */
mapping (address => uint256) balances;
/* Token constructor */
function Token(uint256 _exchangeRate, string _name, string _symbol) {
exchangeRate = _exchangeRate;
name = _name;
owner = msg.sender;
symbol = _symbol;
}
function getBalance(address account) returns (uint256 balance) {
return balances[account];
}
}
TestToken.sol
pragma solidity ^0.4.8;
// Framework libraries
import "truffle/Assert.sol";
import "truffle/DeployedAddresses.sol";
// Custom libraries and contracts
import "../contracts/Token.sol";
contract TestToken {
function testExchangeRate() {
Token token = new Token(500, "Dollar", "$");
uint256 expected = 500;
Assert.equal(token.exchangeRate(), expected, "The exchange rate should be 500 tokens for 1 ETH");
}
function testSymbol() {
Token token = new Token(500, "Dollar", "$");
Assert.equal(token.symbol(), "$", "The symbol of the token should be $");
}
}
And I get this error when I try to execute it:
Error: Member "equal" is not available in type(library Assert) outside of storage.
Assert.equal(token.symbol(), "$", "The symbol of the token should be $");

Compiliation failed. See above.
