[FIXED] Custom test of http header with spring-test-mvc

Issue

I'm testing my MVC service with spring-test-mvc I used something like:

MockMvc mockMvc = standaloneSetup(controller).build();
mockMvc.perform(get("<my-url>")).andExpect(content().bytes(expectedBytes)).andExpect(content().type("image/png"))
       .andExpect(header().string("cache-control", "max-age=3600"));

Which worked fine.

Now I changed the cache image to be random in a specific range. For example, instead of 3600 it could be 3500-3700. I'm trying to figure out how I can get the header value and do some tests on it instead of using this pattern of andExpect.

Solution

Perhaps you mean something like this.

    MvcResult mvcResult = mvc.perform(get("/")).andReturn();
    String headerValue = mvcResult.getResponse().getHeader("headerName");
