Description-en: module to ensure that tests needing a display have one
When testing GUI applications, sometimes applications or modules absolutely
insist on a display, even just to load a module without actually showing any
objects.
.
Regardless, this makes GUI applications pretty much impossible to build and
test on headless or automated systems. And it fails to the point of not even
running the Makefile.PL script because a dependency needs a display so it can
be loaded to find a version.
.
In these situations, what is needed is a fake display.
.
The Test::NeedsDisplay module will search around and try to find a way to load
some sort of display that can be used for the testing.
