Since we declared RESTful endpoints as Java methods with annotations, normal unit testing techniques can be employed. The de facto unit testing library for Java is JUnit. (http://www.junit.org). JUnit is a simple framework used for writing repeatable tests. The following code snippet illustrates how one can test a RESTful endpoint:
public class AvailabilityResourceTest { @Test public void testGetAvailability() throws Exception { AvailabilityService service = ... AvailabilityResource resource = new AvailabilityResource(service); WebRequest request = ... // invalid from date ApiResponse response = resource.getAvailability(null, "2017-01-02", "1", request); assertEquals(Status.ERROR, response.getStatus()); assertEquals(17, response.getError().getErrorCode()); // from is after until response = resource.getAvailability("2017-01-03", "2017-01-02", "1", request); assertEquals(Status.ERROR, response.getStatus()); assertEquals...
