Class LocalServiceTestHelper

  • java.lang.Object
    • com.google.appengine.tools.development.testing.LocalServiceTestHelper

  • public class LocalServiceTestHelper
extends java.lang.Object
    Helper class for testing against local app engine services. Construct the helper with one LocalServiceTestConfig instance for each service that you wish to access as part of your test. Then call setUp() before each test executes and tearDown() after each test executes. No specific test-harness is assumed, but here's a JUnit 3 example that uses task queues and the datastore. 
     public void MyTest extends TestCase {

   private final LocalServiceTestHelper helper = new LocalServiceTestHelper(
     new LocalTaskQueueTestConfig(), new LocalDatastoreServiceTestConfig());

   @Override
   public void setUp() {
     super.setUp();
     helper.setUp();
   }

   @Override
   public void tearDown() {
     helper.tearDown();
     super.tearDown();
   }
 }

      • newEnvironment

        protected com.google.apphosting.api.ApiProxy.Environment newEnvironment()
        Constructs the ApiProxy.Environment that will be installed. Subclass and override to provide your own implementation.

      • newLocalServerEnvironment

        protected LocalServerEnvironment newLocalServerEnvironment()
        Constructs the LocalServerEnvironment that will be installed. Subclass and override to provide your own implementation.

      • newLocalServerEnvironment

        protected LocalServerEnvironment newLocalServerEnvironment(java.lang.Integer apiServerPort)

      • tearDown

        public final void tearDown()
        Tear down the environment in which tests that use local services can execute.

      • endRequest

        public static void endRequest()
        Indicate the request has ended so that local services can do any post request work. This method is optional and is automatically done in tearDown(). You only need to call this method if you want to call tearDown() from your own tearDown / @After method but need to end the request to verify any behavior.

      • getApiProxyLocal

        public static ApiProxyLocal getApiProxyLocal()
        Convenience function for getting ahold of the currently registered ApiProxyLocal.

      • getLocalService

        public static LocalRpcService getLocalService(java.lang.String serviceName)
        Convenience function for getting ahold of a specific local service. For example, to get ahold of the LocalDatastoreService you would call getLocalService(LocalDatastoreService.PACKAGE).
