Test errors

I use linecache2-1.0.0, unittest2 1.0.1.
Output of test suite for traceback2 trunk:

Apparently problem is due to older version of testtools.
I suggest to specify minimal required version of testtools in test-requirements.txt.

[Arfrever]

Tests pass with testtools 1.0.0 and fail with testtools 0.9.39.

Thanks for report, but since 0.9.39 is an old release I don't think it's worth to update test-requirements.txt.
