Description
test_configure_screen uses the DISPLAY environment variable, which is only relevant to X11; and the purpose of the test is to set the -screen option for a toplevel, which is only useful on Tk for X11, since Tk for the Win32 or Aqua windowing systems only support a single “screen” (called :0 by default).
I use XQuartz installed from MacPorts, and so the DISPLAY environment variable is usually set. test_configure_screen tries to use DISPLAY even if I am running the test on Tk Aqua:
