9.springboot单元测试

1.引入依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
    <scope>test</scope>
</dependency>

2.简单测试实例如下：

@RunWith(SpringRunner.class) //底层用junit  SpringJUnit4ClassRunner
@SpringBootTest(classes = {Demo1Application.class})//启动整个springboot工程
public class Demo1Test {
    @Test
    public void test1() {
        System.out.println("hahah");
        TestCase.assertEquals(1, 1);
    }
    @Test
    public void Test2() {
        System.out.println("success");
        TestCase.assertEquals(1, 1);
    }
}

注：
1.@SpringBootTest(classes = {Demo1Application.class})指定main方法入口
2.两个test一块测运行整个class，如果只测试其中一个选中测试的方法运行

3.使用MockMvc模拟http请求测试

@RunWith(SpringRunner.class)//底层用junit  SpringJUnit4ClassRunner
@SpringBootTest(classes= {Demo1Application.class})//启动整个springboot工程
@AutoConfigureMockMvc
public class MockMvcTest {
    
    @Autowired
    private MockMvc mockMvc; 
    
    @Test
    public void testApi() throws Exception {
        MvcResult mvcResult = mockMvc.perform(MockMvcRequestBuilders.get("/testjson")).andExpect(MockMvcResultMatchers.status().isOk()).andReturn();
        int status = mvcResult.getResponse().getStatus();
        System.out.println(status);
    }
}
