### Question:
ProxyRepository extends AbstractRepository implements RepositoryResolverClient { @Override public RepositoryConnection getConnection() throws RepositoryException { return getProxiedRepository().getConnection(); } ProxyRepository();  ProxyRepository(String proxiedIdentity);  ProxyRepository(RepositoryResolver resolver, String proxiedIdentity); final void setProxiedIdentity(String value); String getProxiedIdentity(); @Override final void setRepositoryResolver(RepositoryResolver resolver); @Override void setDataDir(File dataDir); @Override File getDataDir(); @Override boolean isWritable(); @Override RepositoryConnection getConnection(); @Override ValueFactory getValueFactory();  }### Answer:
@Test public final void addDataToProxiedAndCompareToProxy() throws RepositoryException, RDFParseException, IOException { proxied.initialize(); RepositoryConnection connection = proxied.getConnection(); long count; try { connection.add(Thread.currentThread().getContextClassLoader().getResourceAsStream("proxy.ttl"), "http: count = connection.size(); assertThat(count).isNotEqualTo(0L); } finally { connection.close(); } connection = repository.getConnection(); try { assertThat(connection.size()).isEqualTo(count); } finally { connection.close(); } }
