Sorry, I'm not immediately seeing how to do this in the context of the test. 
Could you be more explicit?

In the meantime, I tried

    make -C test x-dnd-tests TEST_INTERACTIVE=yes

and the *ert* buffer reported

F x-dnd-tests-do-direct-save
     (error "Invalid selection type: XdndSelection")

Does that help?

By the way, I should have said in my original report that I do an out-of-tree 
build.  I'll try an in-tree build after sending this message to see if I still 
get the test failure.
