@davidanthoff can you take a look at my (numerous) attempts to get the dependencies tests passing ... I have it working for some tests with #master but that might not be what we want and I'm still failing a few tests i.e. MacOS Julia 1.1 ...

@davidanthoff nice ... Travis looks happy!

[davidanthoff]
