Streaming Responses
You can use WebTestClient
to test 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
bind to a running server,
or when using Spring Boot,
test with a running server.
MockMvcWebTestClient
does support asynchronous responses, and even streaming responses.
The limitation is that it can’t influence the server to stop, and therefore the server
must finish writing the response on its own.
