pub async fn start(tasks: usize) -> JoinHandle<()>Expand description
Start the test once tasks tasks are ready for execution
This should be called after at least tasks tasks have been spawned on the executor,
wrapped by new_task.
This will start executing the tasks in a random but reproducible order, and then return
as soon as the tasks tasks have started executing.
This returns a JoinHandle, that you should join if you want to catch panics related to
lock handling.
