This works, but isn't very nice. Better to use
context.setFeature(f)
(behind the scenes it's doing the same, but is more descriptive and
has some extra checks,
Dear Nyall,

actually there are linux only instructions only if you want to run test
locally. Once you make a pull request, travis runs also for code snippets
