unittest reports wrong result if group setup fails

[jmesserly]

unittest will happily report "PASS" even if the group setup failed. I know this happens in the html configuration (see example below), not sure if it happens in other configurations.

I expect a failure, but this is the result. Note that only 1/1 tests ran:

---

PASS
1 PASS Expectation: Color first.
All 1 tests passed

---

Here's the code:

---

library('bug_example');

import('../dart/dart/lib/unittest/html_config.dart');

import('../dart/dart/lib/unittest/unittest.dart');

main() {
  useHtmlConfiguration();
  group('Color', () {
    test('first', () {
      Expect.isTrue(true);
    });

    throw new Exception('foobar');

    test('second', () {
      Expect.isTrue(true);
    });
  });
}
