what does 'Skipped' mean?


looking on here
i see some of the tests have ‘skipped’ written, what does this mean?
does it mean skipped because of course it will run, or skipped because it will not run, or skipped because the tester couldn’t be bothered, or what?

im trying to find a phone that will run ue4 for as little cost as possible.
i dont mind if it doesnt support full hdr and all that, just as long as it will run a 3D app, not 2d, there are better engines for that.
if you have a low cost/older phone that runs ue4, what is it?
right now the cheapest seems to be a galaxy s2, how does it handle ue4?
