### Question:
ProxyServiceHelper { @AnyThread public void dump(@NonNull final IndentingPrintWriter ipw) { mProxyNetworkFactory.dump(ipw); mProxyNetworkAgent.dump(ipw); } ProxyServiceHelper(
            final Context context,
            final NetworkCapabilities capabilities,
            final ProxyLinkProperties proxyLinkProperties); @MainThread void startNetworkSession(@Nullable final String reason,
            ProxyNetworkAgent.Listener callback); @MainThread void stopNetworkSession(@Nullable final String reason); @MainThread void setMetered(final boolean isMetered); @MainThread void setNetworkScore(final int networkScore); @AnyThread int getNetworkScore(); @MainThread void setCompanionName(@Nullable final String companionName); @AnyThread void dump(@NonNull final IndentingPrintWriter ipw); static final int CAPABILITIES_UPSTREAM_BANDWIDTH_KBPS; static final int CAPABILITIES_DOWNSTREAM_BANDWIDTH_KBPS; }### Answer:
@Test public void testDump() { mProxyServiceHelper.dump(mockIndentingPrintWriter); verify(mockProxyNetworkFactory).dump(mockIndentingPrintWriter); }
