how to treat controller exception with mockmvc

I am using MockMVC to test my controller.

I have the following controller:

public class A{

    ...

    @RequestMapping("/get")
    public List<ADTO> get(@RequestParam(defaultValue = "15", required = false) Integer limit) throws IOException {
        if(limit <= 0 || limit >= 50){
            throw new IllegalArgumentException();
        }
        ...
        return aDTOs;
    }

}

And my current test looks like this:

@Test
public void testGetAllLimit0() throws Exception {
    mockMvc.perform(get("/A/get")
            .param("limit","0")
            )
            .andDo(print())
            .andExpect(...);
}

I am instantiating MockMVC with this:

@Before
public void setup() {
    this.mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).build();
}

How can I take care of that exception thrown in my controller?
