MockMvc integration

If you want to use the AssertJ support but have invested in the original MockMvc API, MockMvcTester offers several ways to integrate with it.

If you have your own RequestBuilder implementation, you can trigger the processing of the request using perform. The example below showcases how the query can be crafted with the original API:

// Static import on MockMvcRequestBuilders.get
assertThat(mockMvc.perform(get("/hotels/{id}", 42)))
		.hasStatusOk();

Similarly, if you have crafted custom matchers that you use with the .andExpect feature of MockMvc you can use them via .matches. In the example below, we rewrite the preceding example to assert the status with the ResultMatcher implementation that MockMvc provides:

// Static import on MockMvcResultMatchers.status
assertThat(mockMvc.get().uri("/hotels/{id}", 42))
		.matches(status().isOk());

MockMvc also defines a ResultHandler contract that lets you execute arbitrary actions on MvcResult. If you have implemented this contract you can invoke it using .apply.
