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();
>        }
>      }

  Parameters:
    `timeZone` - the time zone

  Constructs the `LocalServerEnvironment` that will be installed. Subclass and override to provide your own implementation.

### tearDown

    public final void tearDown()

  Tear down the environment in which tests that use local services can execute.

### getApiProxyLocal

### 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)`.
