require.LessOrEqual(t, maxOngoing, graphsyncThrottle)
// The eventing systems across go-data-transfer and go-graphsync
// are racy, and that's why we can't enforce graphsyncThrottle exactly,
// without making this test racy.
//
// Essentially what could happen is that the graphsync layer starts the
// next transfer before the go-data-transfer FSM has the opportunity to
// move the previously completed transfer to the next stage, thus giving
// the appearance that more than graphsyncThrottle transfers are
// in progress.
//
// Concurrency (20) is x10 higher than graphsyncThrottle (2), so if all
// 20 transfers are not happening at once, we know the throttle is
// in effect. Thus we are a little bit lenient here to account for the
// above races and allow up to graphsyncThrottle*2.
