I don't like testing "example" here as well. This test should focus on testing
that assets from dependencies get included; a separate test should test that
asset directories are included in every directory under build.

[Bob Nystrom, 2014/01/28 23:02:04]

In order to test that they are included, they have to be included *somewhere*,
so this test would be implicitly testing some top level directory. I figured it
was simplest to test more than one of them here instead of having several 90%
identical tests.

[nweiz, 2014/01/29 01:24:35]

I'd rather just test (any) one directory and consider the behavior of "does the
same thing to all top-level directories" to be orthogonal to this test.

[Bob Nystrom, 2014/01/29 19:03:38]

We don't tend to go minimal in our integration tests. For example, even if this
test only tests one top level directory, you'll note its still testing assets
both in the main directory and in subdirectories of asset.
