Hi,
I am trying to unit testing. I copied the sample code on the site as
is, but I get the error below.
Here is the unit test code
import com.google.appengine.api.datastore.DatastoreService;
import com.google.appengine.api.datastore.DatastoreServiceFactory;
import com.google.appengine.api.datastore.Entity;
import com.google.appengine.api.datastore.Query;
import
com.google.appengine.tools.development.testing.LocalDatastoreServiceTestConfig;
import
com.google.appengine.tools.development.testing.LocalServiceTestHelper;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import static org.junit.Assert.*;
public class LocalDatastoreTest {
private final LocalServiceTestHelper helper =
new LocalServiceTestHelper(new
LocalDatastoreServiceTestConfig());
@Before
public void setUp() {
helper.setUp();
}
@After
public void tearDown() {
helper.tearDown();
}
// run this test twice to prove we're not leaking any state across
tests
private void doTest() {
DatastoreService ds =
DatastoreServiceFactory.getDatastoreService();
assertEquals(0, ds.prepare(new Query("yam")).countEntities());
ds.put(new Entity("yam"));
ds.put(new Entity("yam"));
assertEquals(2, ds.prepare(new Query("yam")).countEntities());
}
@Test
public void testInsert1() {
doTest();
}
@Test
public void testInsert2() {
doTest();
}
}
Here is the error
com.google.apphosting.api.ApiProxy$CallNotFoundException: The API
package 'datastore_v3' or call 'Count()' was not found.
