nit: It could be better if the rest of this test is made to a separate test in
this file. But that's optional, feel free to ignore.

Done.

typo (assignemt)

[jdomingos, 2013/09/11 19:15:28]

Done.

[vabr (Chromium), 2013/09/11 17:31:24]

nit: Adding
<< " group name = " << it->first
might produce more useful error messages in case of failure.

[jdomingos, 2013/09/11 19:15:28]

Done.
