+	 * 				.exchange()
+	 * 				.expectStatus().isFound()
+	 * 				.expectHeader().location("/persons/Joe")
+	 * 				.expectBody().isEmpty();
+	 *
+	 * MockMvcTestClient.resultActionsFor(result)
+	 * 		.andExpect(model().size(1))
+	 * 		.andExpect(model().attributeExists("name"))
+	 * 		.andExpect(flash().attributeCount(1))
+	 * 		.andExpect(flash().attribute("message", "success!"));
+	 * </pre>
+	 *
+	 * <p>Note: this method works only if the {@link WebTestClient} used to
+	 * perform the request was initialized through one of bind method in this
+	 * class, and therefore requests are handled by {@link MockMvc}.
