| /** |
| * Tests if the [AndroidInputDispatcher.sendSwipe] gesture works when specifying the gesture as a |
| * function between two positions. Verifies if the generated MotionEvents for a gesture with a |
| * given duration and a set of keyTimes have the expected timestamps, if the event period would |
| * be different. This is not a situation that can occur in practice, but is necessary to test to |
| * ensure the calculations made by the [AndroidInputDispatcher] are correct. |
| * |
| * The timestamps of the generated events should include all keyTimes, and divide the duration |
| * between those keyTimes as equally as possible with as close to [eventPeriod] between each |
| * successive event as possible. |
| * |
| * This uses a different verification mechanism as the previous tests, because here we need to |
| * calculate the expected timestamps. |
