The tests require some test data.

To install the test data on Debian-based systems, first install core
tools as show at http://wiki.apertium.org/wiki/Debian and then do

    sudo apt-get install apertium-sme-nob apertium-es-en
    mkdir ~/apy-testdata
    cd ~/apy-testdata
    svn co https://svn.code.sf.net/p/apertium/svn/languages/apertium-nno
    cd apertium-nno
    ./autogen.sh
    make -j4

Now go back to the apy directory, and do

    NONPAIRS=~/apy-testdata t/run-tests

to run the tests.
