Java Utilities

  • RestAssuredSpecFactory - Create rest-assured request spec with all wapi required headers
public class Example {
        public static void main(String[] args) throws Exception {
            RestAssuredSpecFactory.givenARequestSpecificationWithAllRequiredHeaders()
                   .when()
                   .post("http://exmaple.com")
                   .then().statusCode(200);
       
    }
}
  • AtamApplication - Acceptance Test as Monitors bootstrap
public class ExampleAtamApplication extends Atam4jMainApplication {
        public static void main(String[] args) throws Exception {
        if (args == null || args.length == 0) {
            args = new String[]{"server", getAtam4JConfigFile()};
        }
        new ExampleAtamApplication().run(args);
    }
}
  • ApiTest - Bootstrap api tests by starting and shutting down the test application
class ExampleApiTest extends ApiTest {

    @Override
    void startApplication() {
        Spark.start();
    }

    @Override
    void stopApplication() {
        Spark.stop();
    }

    @Override
    void loadTestApplicationProperties() {
        try {
            properties.load(getClass().getClassLoader().getResourceAsStream("test.properties"));
        } catch (IOException | URISyntaxException e) {
            e.printStackTrace();
        }
    }
}
  • WiremockBasedApiTest - Bootstrap api tests by starting and shutting down the test application and wiremock
class ExampleWiremockBasedApiTest extends WireMockBasedApiTest {

    @Override
    void startApplication() {
        Spark.start();
    }

    @Override
    void stopApplication() {
        Spark.stop();
    }

    @Override
    void loadTestApplicationProperties() {
        try {
            properties.load(getClass().getClassLoader().getResourceAsStream("test.properties"));
        } catch (IOException | URISyntaxException e) {
            e.printStackTrace();
        }
    }
}
  • JsonParser - quickly serialize/deserialize json backed by jackson
    public class DummyExample {
           
        static class Dummy {
    
    
            public String getName() {
                return name;
            }
    
            private String name;
    
            public void setName(String name) {
                this.name = name;
            }
    
        }

        public static void main(String[] args) {
        
            Dummy d = JsonParser.deserialize("{\"name\":\"Dummy\"}", Dummy.class);
            String payload = JsonParser.serialize(ImmutableMap.of("abc", "123"));
        }
    }
  • StubBuilder - wiremock backed stubbing
public class Example {
         public static void main(String[] args) throws Exception {
             StubBuilder stubServer = new StubBuilder().startWireMock();
             
             //stubbing
             stubServer.givenWiremockWillReturnCode(200);
             
             //set wiremock as proxy and record conversation with a third party service for future use
             StubRecorder recorder = stubBuilder.recorder("https://example.com", 443).record(
                             () -> requestSpecification
                                     .when()
                                     .get("/blueRed")
                                     .then()
                                     .statusCode(404)
                     );
             
                     
             List<StubMapping> mappings = recorder.saveRecording().then().getRecording();
             
     }
 }
