| <p> Test case for Bug <a href="https://bugs.webkit.org/show_bug.cgi?id=18655">18655</a>: [XHR] onProgress event |
| needs to be dispatched according to what the specification states </p> |
| <p> This test verify that we "dispatch a progress event called progress about |
| every 50ms or for every byte received, whichever is least frequent".</p> |
| <p> You should see a sequence of 5 PASSED. </p> |
