MockBean 單元測試

案例一   官方文檔：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工具測試，UserVehicleControkker.class代表對UserVehicleControkker 進行測試*/ 

@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數據的傳遞，即傳一個對象

官方文檔的推薦：

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數據*/ String content = "{\"make\":\"Ford\",\"model\":\"Focus\"}"; 
 /**使用預言：第一個：assertThat進行數據的json格式的轉換，以及傳遞數據*/ 
assertThat(this.json.parse(content)) .isEqualTo(new VehicleDetails("Ford", "Focus"));
/**使用預言：assertThat:傳遞數據，並得到自己制作的數據，並且期望返回的數據是否是 “Ford”*/
 assertThat(this.json.parseObject(content).getMake()).isEqualTo("Ford");
 } 
}

/*個人的json數據：包裝成一個對象，傳遞過去*/
