- - org.springframework.boot.test.json.JacksonTester<T>

类型参数:: T - the type under test

public class JacksonTester<T>
extends AbstractJsonMarshalTester<T>

AssertJ based JSON tester backed by Jackson. Usually instantiated via initFields(Object, ObjectMapper), for example:

 public class ExampleObjectJsonTests {

     private JacksonTester<ExampleObject> json;

     @Before
     public void setup() {
         ObjectMapper objectMapper = new ObjectMapper();
         JacksonTester.initFields(this, objectMapper);
     }

     @Test
     public void testWriteJson() throws IOException {
         ExampleObject object = //...
         assertThat(json.write(object)).isEqualToJson("expected.json");
     }

 }

See AbstractJsonMarshalTester for more details.
