public abstract class ProviderTestCase2<T extends ContentProvider> extends AndroidTestCase
ContentProvider and for testing your app code with an
isolated content provider. Instead of using the system map of
providers that is based on the manifests of other applications, the test
case creates its own internal map. It then uses this map to resolve providers
given an authority. This allows you to inject test providers and to null out
providers that you do not want to use.
This test case also sets up the following mock objects:
IsolatedContext that stubs out Context methods that might
affect the rest of the running system, while allowing tests to do real file and
database work.
MockContentResolver that provides the functionality of a
regular content resolver, but uses IsolatedContext. It stubs out
ContentResolver.notifyChange(Uri, ContentObserver, boolean) to
prevent the test from affecting the running system.
IsolatedContext.
This framework is set up automatically by the base class' setUp() method. If you
override this method, you must call the super method as the first statement in
your override.
In order for their tests to be run, concrete subclasses must provide their own
constructor with no arguments. This constructor must call
ProviderTestCase2(Class, String) as its first operation.

the underlying data source.

Creates a new

the provider under test within the isolated environment.

Creates a new content provider of the same type as that passed to the test case class,
with an authority name set to the authority parameter, and using an SQLite database as
the underlying data source. The SQL statement parameter is used to create the database.
This method also creates a new MockContentResolver and adds the provider to it.
Both the new provider and the new resolver are put into an IsolatedContext
that uses the targetContext parameter for file operations and a MockContext
for everything else. The IsolatedContext prepends the filenamePrefix parameter to
file, database, and directory names.
This is a convenience method for creating a "mock" provider that can contain test data.

database and its tables. The format is the same as that generated by the
