// 1. Load 1.6s of data and ensure that canplay event is fired.
|
|
// 2. Load data to have a complete buffered range from 0 to duration and ensure that canplaythrough is fired.
|
|
// 3. Seek to an area with no buffered data, and ensure that readyState goes back to HAVE_METADATA
|
|
// 4. Load 1.6s of data at the seek position and ensure that canplay is fired and that readyState is now HAVE_FUTURE_DATA
|
|
// 5. Start playing video and check that once it reaches a position with no data, readyState goes back to HAVE_CURRENT_DATA and waiting event is fired.
|
|
// 6. Add 1.6s of data once video element fired waiting, that canplay is fired once readyState is HAVE_FUTURE_DATA.
|
|
// 7. Finally load data to the end and ensure that canplaythrough is fired and that readyState is now HAVE_ENOUGH_DATA
