52 // The frame test helpers coordinate frame loads in a carefully choreographed
53 // dance. Since the parser is threaded, simply spinning the run loop once is not
54 // enough to ensure completion of a load. Instead, the following pattern is
55 // used to ensure that tests see the final state:
56 // 1. Post a task to trigger a load (LoadTask/LoadHTMLStringTask/ReloadTask).
57 // 2. Enter the run loop.
58 // 3. Posted task triggers the load, and starts pumping pending resource
59 // requests using ServeAsyncRequestsTask.
60 // 4. TestWebFrameClient watches for didStartLoading/didStopLoading calls,
61 // keeping track of how many loads it thinks are in flight.
62 // 5. While ServeAsyncRequestsTask observes TestWebFrameClient to still have
63 // loads in progress, it posts itself back to the run loop.
64 // 6. When ServeAsyncRequestsTask notices there are no more loads in progress,
65 // it exits the run loop.
66 // 7. At this point, all parsing, resource loads, and layout should be finished.
