How to mock http header in MockRestServiceServer?

Question

I'm using MockRestServiceServer to mock an external webservice xml response. That already works fine, but how can I also mock the http header inside the response, not only the response body?

    @MockBean
    private RestTemplate restTemplate;

    private MockRestServiceServer mockServer;

    @Before
    public void createServer() throws Exception {
        mockServer = MockRestServiceServer.createServer(restTemplate);
    }

    @Test
    public void test() {
        String xml = loadFromFile("productsResponse.xml");
        mockServer.expect(MockRestRequestMatchers.anything()).andRespond(MockRestResponseCreators.withSuccess(xml, MediaType.APPLICATION_XML));
    }

Answer 1

Just follow your withSuccess method with headers method.

mockServer
       .expect(...)
       .andRespond(withSuccess().headers(...));
