I had not idea this existed, that's pretty cool!

could we call `source test/test.sh` here instead? it runs "all_tests.dart" but
also validates the output of the compiler, runs the analyzer, and checks that
all files are formatted correctly.

Yes, but let me get this in first.

I was having trouble getting tesh.sh to pass on travis. Wanted to get something
in first.

if it helps, we can move the diff'ing of expected output into the Dart test
code.
but test.sh is still nice because it runs the analyzer :)
