tests.jl does not test the run function at all

[astrieanna]

Just executing the run function would save us from a lot of deprecation/unexport/rename bugs.
Is there a way we can test running that function, even though it never returns?

[rened]

perhaps something along the lines of

context("test run") do
@async run()
sleep(0.5) # to allow for startup if any
# actual tests here, requesting from the server
end
