The first step of running tests with testr is listing all of the tests
using 'discover'. That listing is failing probably due to an import
error but the actual error was in that copious output... If you grep
through it for import you should find it. Then you will need to figure
out why that module could not be imported.

It should be noted that the error message is much clearer using the
latest revision in the testrepository repo but testrepository has not
been released with the fix in it yet. I think lifeless is trying to
move to git before that happens.
