seen when running the tests in the installed location:

the test expects:

Traceback (most recent call last):
  File "<console>", line 1, in <module>
ValueError

but it gets:

Traceback (most recent call last):
  File "/usr/lib/python3.5/code.py", line 91, in runcode
    exec(code, self.locals)
  File "<console>", line 1, in <module>
ValueError

same for the other failing test case.
