Rules

The response to getCode() should have some characters that aren’t either 0 or x.

To test it out, you can use the following with a local testrpc:

web3.eth.sendTransaction({data:'BYTECODE', from:web3.eth.accounts[0]}); web3.eth.getCode('THE_ADDRESS');

Or you can use the evm command that comes with Geth:

evm --debug --code BYTECODE run .
