testrpc-sc doesn't return contract's require and assert error string along with error message as it has been updated in ganache and truffle. So tests checking the returned error message works fine with truffle test but breaks when trying to get coverage.
Having same issue here as well when using truffle's latest beta version
same issue here as well, any solutions?
This is fixed in 0.6.0
