Schauen wir uns an, wie wir das machen können.

Let's look at how we can make that work.

## pytest.mark.anyio

If we want to call asynchronous functions in our tests, our test functions have to be asynchronous. AnyIO provides a neat plugin for this, that allows us to specify that some test functions are to be called asynchronously.

// MASQUERADE  all  --  0.0.0.0/0            0.0.0.0/0            /* kubernetes service traffic requiring SNAT */ mark match 0x4000/0x4000

// :KUBE-MARK-MASQ - [0:0]
// Chain KUBE-MARK-MASQ (0 references)
// target     prot opt source               destination

	// this so that it is easier to flush and change, for example if the mark
	// value should ever change.

	proxier.natRules.Write(
		"-A", string(kubePostroutingChain),
		"-m", "mark", "!", "--mark", fmt.Sprintf("%s/%s", proxier.masqueradeMark, proxier.masqueradeMark),
		"-j", "RETURN",
	)
	// Clear the mark to avoid re-masquerading if the packet re-traverses the network stack.
	proxier.natRules.Write(

	}
	return nil
}

func (l *lazyInit) doSlow(f func() error) error {
	l.m.Lock()
	defer l.m.Unlock()
	if atomic.LoadUint32(&l.done) == 0 {
		if err := f(); err != nil {
			return err
		}
		// Mark as done only when f() is successful
		atomic.StoreUint32(&l.done, 1)
	}
	return nil
