使用Spring MockMVC对controller做单元测试

1、对单一controller做测试。

import org.junit.Before;
import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.MediaType;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.MvcResult;
import org.springframework.test.web.servlet.ResultActions;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.web.WebAppConfiguration;

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration("classpath:")
@ContextConfiguration("/data/spring-test.xml")
public class CommonCtrlTest {

    private MockMvc mockMvc;

    @Autowired
    CommonCtrl commonCtrl;

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

    @Test
    public void testHello() throws Exception {
        ResultActions resultActions = this.mockMvc.perform(
                MockMvcRequestBuilders.get("/test").accept(MediaType.APPLICATION_JSON));
        MvcResult mvcResult = resultActions.andReturn();
        String result = mvcResult.getResponse().getContentAsString();
        System.out.println("response:" + result);
    }
}

2、对整个环境做测试，包括Interceptor。

import org.junit.Before;
import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.web.context.WebApplicationContext;
import outfox.course.weixinkaoshen.dao.AbstractTest;

import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultHandlers.print;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;

public class TestKaoshenCtrl extends AbstractTest{
    @Autowired
    private WebApplicationContext wac;

    private MockMvc mockMvc;

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

    @Test
    public void testAddUser() throws Exception {
        mockMvc.perform((get("/test/get").param("id", "1")))
                .andExpect(status().isOk()).andDo(print());
    }
}
