Move comma to right after onTest.

+    doTest = onTest;
+    doDone = onDone;
+    processDirectory();
+  }
+
+  void processDirectory() {
+    Directory dir = new Directory(directoryPath);
+    if (!dir.existsSync()) {
+      dir = new Directory(".." + pathSeparator + directoryPath);
+      if (!dir.existsSync()) return;

Instead of just returning here, shouldn't we throw an exception? If we do
nothing it will look like the tests are all passing when in fact we did not find
them.

+      // TODO(ager): Use dir.errorHandler instead when it is implemented.
+    }
+    dir.fileHandler = processFile;
+    dir.doneHandler = doDone;
+    dir.list(false);
+  }
+
+  void processFile(String filename) {
+    if (filename.endsWith(".dart")) {

Sorry, my mistake. I think currently there might be other files than test files
in the directories. The right thing is probably to keep the test for 'Test.dart'
for now.

+      int start = filename.lastIndexOf(pathSeparator);
+      String displayName = filename.substring(start + 1, filename.length - 5);
+      // TODO(whesse): Gather test case info from status file and test file.
+      doTest(new TestCase(displayName,
+                          shellPath,
+                          ["--enable_type_checks",
+                              "--ignore-unrecognized-flags",

Indentation. I would do:

["--...",
 "--...",
 filename],

+                              filename ],
+                          completeHandler,
+                          new Set.from([PASS, FAIL, CRASH, TIMEOUT])));
+    }
+  }
+  
+  void completeHandler(TestCase testCase) {
+    TestOutput output = testCase.output;
+    print("Exit code: ${output.exitCode} Time: ${output.time}");
+  }
+}
