Dartest CL - Please review

client/testing/dartest/README.txt

+DARTest is a test infrastructure for Dart applications.
+
+To use the in-app test runner, follow these steps:
+1. Import dartest as a library.
+#import('dart/testing/unittest/unittest_dartest.dart');
+#import('dart/testing/dartest/dartest.dart');
+
+
+2. Write tests for the application in a function, call the test functions and
+then run dart:
+
+test('Test Description',(){
+  Expect.equals(3, myAddFunc(1,2));
+});
+new DARTest().run();
+
+
+3. Thats all! Now when you compile and run your application, you should 
+see the DARTest in-app overlay window.
+
+For an example, see tests in $DART/client/tests/client/samples/total/total_dartest.dart
