Erros in npm test on ethereum-testing-reference project

[gladsjr]

I've cloned the project and run npm install. Trying npm test, I get what follows.
I've changed the solc version in package.json to 0.4.10. Nothing got different.

npm ERR! Test failed. See above for more details.

There are several changes to be made to the code then it runs again (partly):

1. replace all "abstract" by something like "abstractcontract"
2. all modifiers (_) must end with a semicolon, e.g. if (msg.sender==owner) _;
3. Nice to have: since solidity 0.4.0 its recommended to specify the version with a pragma line first in the solidity file: e.g. "pragma solidity ^0.4.10

But then still, there is another error when running it locally (haven't tested it in the ethereum studio):

I'm not exactly sure where that comes from...
