MockContentResolver in a ServiceTestCase null pointers
I'm trying to create a Service in a TDD-ish manner and to that end I have created the following test. The service basically polls a Web Service and puts new information into a Content Provider. Since it is a service, I am using the Content Provider that it will be storing information into as the oracle of the test.
I think what I want to do is create a MockContentResolver in order to achieve this but there is a lack of examples of it outside of a ProviderTestCase2 class. When I run this script however it it null pointers on the addProvider line.
Does anyone have an example of creating/accessing a mocked out content resolver? In a ServiceTestCase?
public class OnDemandPollingServiceTests extends ServiceTestCase<OnDemandJobFetchingService> {
private MockContentResolver mContentResolver;
public OnDemandPollingServiceTests() {
super(OnDemandJobFetchingService.class);
}
protected void setUp() throws Exception {
super.setUp();
mContext = getContext();
ContentProvider cp = new OnDemandJobInfoProvider();
mContentResolver.addProvider(OnDemandJobInfoProvider.AUTHORITY, cp);
}
protected void tearDown() throws Exception {
super.tearDown();
}
public void testJobInsertion() {
Uri url = Jobs.Job开发者_运维知识库sColumns.CONTENT_URI;
Cursor cursor;
cursor = mContentResolver.query(url, null, null, null, null);
int before = cursor.getCount();
cursor.close();
Intent startIntent = new Intent();
startIntent.setClass(mContext, OnDemandJobFetchingService.class);
startService(startIntent);
cursor = mContentResolver.query(url, null, null, null, null);
int after = cursor.getCount();
cursor.close();
assertTrue(before != after);
}
}
To me it seems like you have never instantiated your mContentResolver
(you don't have a line like mContentResolver = new MockContentResolver();
.
