Function advanceUntil

lib/screentracker/pty_conversation_test.go:73–84

advanceUntil advances the mock clock one event at a time until done returns true. Because the snapshot TickerFunc is always pending and WaitFor reuses a single timer via Reset, there is always at least one event to advance.

(ctx context.Context, t *testing.T, mClock *quartz.Mock, done func() bool)

// true. Because the snapshot TickerFunc is always pending and WaitFor reuses a
// single timer via Reset, there is always at least one event to advance.
func advanceUntil(ctx context.Context, t *testing.T, mClock *quartz.Mock, done func() bool) {
	t.Helper()
	for !done() {
		select {
		case <-ctx.Done():
			t.Fatal("context cancelled waiting for condition")
		default:
		}
		_, w := mClock.AdvanceNext()
		w.MustWait(ctx)
	}
}

// sendAndAdvance calls Send() in a goroutine and advances the mock clock until
// Send completes.
