ProviderTestCase2

public abstract class ProviderTestCase2
extends AndroidTestCase

java.lang.Object
↳	junit.framework.Assert
	↳	junit.framework.TestCase
		↳	android.test.AndroidTestCase
			↳	android.test.ProviderTestCase2<T extends android.content.ContentProvider>

This test case class provides a framework for testing a single 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:

An 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.
A MockContentResolver that provides the functionality of a regular content resolver, but uses IsolatedContext. It stubs out notifyChange(Uri, ContentObserver, boolean) to prevent the test from affecting the running system.
An instance of the provider under test, running in an 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.

For more information on content provider testing, please see Content Provider Testing.

                String providerAuthority)

Constructor.

Parameters
`providerClass`	`Class`: The class name of the provider under test
`providerAuthority`	`String`: The provider's authority string

Public methods

getMockContentResolver

Added in API level 3

MockContentResolver getMockContentResolver ()

Gets the MockContentResolver created by this class during initialization. You must use the methods of this resolver to access the provider under test.

Returns
`MockContentResolver`	A `MockContentResolver` instance.

getMockContext

Added in API level 3

IsolatedContext getMockContext ()

Gets the IsolatedContext created by this class during initialization.

Returns
`IsolatedContext`	The `IsolatedContext` instance

getProvider

Added in API level 3

T getProvider ()

Returns the content provider created by this class in the setUp() method.

Returns
`T`	T An instance of the provider class given as a parameter to the test case class.

newResolverWithContentProviderFromSql

Added in API level 3

ContentResolver newResolverWithContentProviderFromSql (Context targetContext, 
                String filenamePrefix, 
                Class<T> providerClass, 
                String authority, 
                String databaseName, 
                int databaseVersion, 
                String sql)

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.

Parameters
`targetContext`	`Context`: The context to use as the basis of the IsolatedContext
`filenamePrefix`	`String`: A string that is prepended to file, database, and directory names
`providerClass`	`Class`: The type of the provider being tested
`authority`	`String`: The authority string to associated with the test provider
`databaseName`	`String`: The name assigned to the database
`databaseVersion`	`int`: The version assigned to the database
`sql`	`String`: A string containing the SQL statements that are needed to create the desired database and its tables. The format is the same as that generated by the sqlite3 tool's `.dump` command.

Returns
`ContentResolver`	ContentResolver A new `MockContentResolver` linked to the provider

Throws
	IllegalAccessException
`InstantiationException`
`IllegalAccessException`

Protected methods

setUp

Added in API level 3

void setUp ()
