// Tests for the UdpSocketManager interface.
// Note: This tests UdpSocketManager together with UdpSocketWrapper,
// due to the way the code is full of static-casts to the platform dependent
// subtypes.
// It also uses the static UdpSocketManager object.
// The most important property of these tests is that they do not leak memory.
