I am attempting to test the update() method of my custom content provider. I receive a null pointer exception due to the getContext() method call within the update() method being null. To alleviate this issue I have attempted implementing Why does AndroidTestCase.getContext().getApplicationContext() return null? to no avail. My test class looks like the following:
public class AddressContentProviderTest extends ProviderTestCase2<AddressContentProvider> {
public AddressContentProviderTest() {
super(AddressContentProvider.class, AddressContentProvider.class.getName());
}
protected void setUp() throws Exception {
super.setUp();
}
public void testInsert() {
Uri CONTENT_URI = Uri.parse("content://" + AddressContentProvider.AUTHORITY + "/address");
AddressContentProvider addressContentProvider = new AddressContentProvider();
ContentValues initialValues = new ContentValues();
boolean isException = false;
Uri returnURI = null;
initialValues.put("country", "test");
initialValues.put("region", "test");
initialValues.put("city", "test");
initialValues.put("state", "FL");
initialValues.put("zip", "90210");
initialValues.put("province", "test");
initialValues.put("geo_location_id", "");
returnURI = addressContentProvider.insert(CONTENT_URI, initialValues);
assertTrue(returnURI != null);
}
The insert method looks like the following:
@Override
public int update(Uri uri, ContentValues values, String where, String[] whereArgs) {
SQLiteDatabase db =dbHelper.getWritableDatabase();
int count;
switch (sUriMatcher.match(uri)) {
case ADDRESS:
count = db.update(ADDRESS_TABLE_NAME, values, where, whereArgs);
break;
default:
throw new IllegalArgumentException("Unknown URI " + uri);
}
getContext().getContentResolver().notifyChange(uri, null);
return count;
}
I'm running my tests using Android 2.3.3 on Platform 10.
So the answer to the problem was to call the getProvider(); method. This gives me access to the AddressContentProvider within the thread of execution;
public void testInsert() {
Uri CONTENT_URI = Uri.parse("content://" + AddressContentProvider.AUTHORITY + "/address");
AddressContentProvider addressContentProvider = getProvider();
ContentValues initialValues = new ContentValues();
//Uri returnURI = null;
initialValues.put("country", "USA");
initialValues.put("region", "test");
initialValues.put("city", "Jacksonville");
initialValues.put("state", "FL");
initialValues.put("zip", "32258");
initialValues.put("province", "test");
initialValues.put("geo_location_id", "");
Uri returnURI = addressContentProvider.insert(CONTENT_URI, initialValues);
assertTrue(returnURI != null);
}
