MockBean 单元测试

案例一   官方文档：https://docs.spring.io/spring-boot/docs/2.0.4.RELEASE/reference/htmlsingle/


import org.junit.*;

import org.junit.runner.*;

import org.springframework.beans.factory.annotation.*;
import org.springframework.boot.test.autoconfigure.web.servlet.*;
import org.springframework.boot.test.mock.mockito.*;

import static org.assertj.core.api.Assertions.*;
import static org.mockito.BDDMockito.*;
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.*;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.*;

@RunWith(SpringRunner.class)
/**使用webMvcTest工具测试，UserVehicleControkker.class代表对UserVehicleControkker 进行测试*/ 

@WebMvcTest(UserVehicleController.class)


public class MyControllerTests {

	@Autowired
	private MockMvc mvc;

	@MockBean
	private UserVehicleService userVehicleService;

	@Test
	public void testExample() throws Exception {
		given(this.userVehicleService.getVehicleDetails("sboot"))
				.willReturn(new VehicleDetails("Honda", "Civic"));
		this.mvc.perform(get("/sboot/vehicle").accept(MediaType.TEXT_PLAIN))
				.andExpect(status().isOk()).andExpect(content().string("Honda Civic"));
	}

}

案例二：jsons数据的传递，即传一个对象

官方文档的推荐：

import org.junit.*;
import org.junit.runner.*;
import org.springframework.beans.factory.annotation.*;
import org.springframework.boot.test.autoconfigure.json.*;
import org.springframework.boot.test.context.*;
import org.springframework.boot.test.json.*;
import org.springframework.test.context.junit4.*;

import static org.assertj.core.api.Assertions.*;

@RunWith(SpringRunner.class)
@JsonTest
public class MyJsonTests {

	@Autowired
	private JacksonTester<VehicleDetails> json;

/**方式一/
	@Test
	public void testSerialize() throws Exception {
		VehicleDetails details = new VehicleDetails("Honda", "Civic");
		// Assert against a `.json` file in the same package as the test
		assertThat(this.json.write(details)).isEqualToJson("expected.json");
		// Or use JSON path based assertions
		assertThat(this.json.write(details)).hasJsonPathStringValue("@.make");
		assertThat(this.json.write(details)).extractingJsonPathStringValue("@.make")
				.isEqualTo("Honda");
	}
/**方式二/
	@Test
	public void testDeserialize() throws Exception {
              /**自己制作一些json数据*/
		String content = "{\"make\":\"Ford\",\"model\":\"Focus\"}";  
              /**使用预言：第一个：assertThat进行数据的json格式的转换，以及传递数据*/ 
assertThat(this.json.parse(content)) .isEqualTo(new VehicleDetails("Ford", "Focus"));
/**使用预言：assertThat:传递数据，并得到自己制作的数据，并且期望返回的数据是否是 “Ford”*/
 assertThat(this.json.parseObject(content).getMake()).isEqualTo("Ford");
 } 
}

/*个人的json数据：包装成一个对象，传递过去*/
