Class BasicJsonTester

java.lang.Object

org.springframework.boot.test.json.BasicJsonTester

public class BasicJsonTester
extends Object

AssertJ based JSON tester that works with basic JSON strings. Allows testing of JSON payloads created from any source, for example:

 public class ExampleObjectJsonTests {

     private BasicJsonTester json = new BasicJsonTester(getClass());

     @Test
     public void testWriteJson() throws IOException {
         assertThat(json.from("example.json")).extractingJsonPathStringValue("@.name")
                                .isEqualTo("Spring");
     }

 }
