should code_transformers export this as a public library? or is there a public
import we can use here?

Heh yes there is, I was copying the pattern from polymer but it looks  like I
can drop this whole file :)

+testPhases(String testName, List<List<Transformer>> phases,
+    Map<String, String> inputFiles, Map<String, String> expectedFiles,
+    [List<String> expectedMessages]) {
+  test(testName, () {
+    var helper = new TestHelper(phases, inputFiles, expectedMessages)..run();
+    return helper.checkAll(expectedFiles).whenComplete(() => helper.tearDown());

`() => helper.tearDown()` replace with `helper.tearDown`?
