"""
Simple test for bsdbd. Minimal adaptations made (2016) from original version to
make the code compile and run under nosetests (unittest). This runs from the
root github directory with a command line like:
nosetests gramps test
where gramps is the directory containing most of the Gramps code, and this file
is in the directory 'test'
