 ===== Streaming Responses
 
-The best way to test streaming responses such as Server-Sent Events is through the

-to perform tests on Spring MVC controllers without a running server. For example:

-			.exchange()
-			.expectStatus().isOk()
-			.expectHeader().contentType("text/event-stream")
-			.returnResult(Person.class);

-	// Use StepVerifier from Project Reactor to test the streaming response
-
-	StepVerifier.create(exchangeResult.getResponseBody())

-			.expectNextCount(4)
-			.consumeNextWith(person -> assertThat(person.getName()).endsWith("7"))

+You can use `WebTestClient` to test <<testing/testing-webtestclient.adoc#webtestclient-stream,streaming responses>>
+such as Server-Sent Events. However, `MockMvcWebTestClient` doesn't support infinite
+streams because there is no way to cancel the server stream from the client side.
+To test infinite streams, you'll need to
