Question

@RequestMapping(value=\"/someURL\", method=GET)
public String myMethod(RedirectAttributes redirectAttributes)
{
   redirectAttribut         


        

Answer 1

You can use MockMvcResultMatchers#flash() which returns a FlashAttributeResultMatchers object which has an attribute() method.

mockMvc.perform(MockMvcRequestBuilders.get("/someURL"))
            .andExpect(MockMvcResultMatchers.model().attribute("rd", "rdValue"))
            .andExpect(MockMvcResultMatchers.flash().attribute("fa", someValueThatEqualsFaValue));

Note that "rd" will be a Model attribute, not a flash attribute.
