Perhaps remove these, since they are in the other test.

[Ivan Posva, 2012/12/05 13:01:29]

Done.

+
+  Expect.equals(3, Cat.ifNull(null, 3), 'Cat.ifNull(null, 3)');
+  Expect.equals(4, Cat.ifNull(4, null), 'Cat.ifNull(4, null)');
+  Expect.equals(5, Cat.ifNull(5, 9), 'Cat.ifNull(5, 9)');
+  Expect.isNull(Cat.ifNull(null, null), 'Cat.ifNull(null, null)');

Write comment: This tests throwing an exception from native code that is called
from an event in the event loop.

[Ivan Posva, 2012/12/05 13:01:29]

Done.

+  try {
+    Cat.throwMeTheBall("ball");
+  } on String catch (e) {
+    Expect.equals("ball", e);
+  }
+  new Timer(0, (_) => Cat.throwMeTheBall("ball"));
+}
