Usage

From source file:com.uphyca.testing.junit3.support.v4.FragmentUnitTestCase.java

/**
 * Start the fragment under test, providing the arguments it supplied. When
 * you use this method to start the fragment, it will automatically be
 * stopped by {@link #tearDown}./*from   w w w . j av a  2s.  c  o  m*/
 * 
 * <p>
 * This method will call onAttach() either onCreate(), but if you wish to
 * further exercise Activity life cycle methods, you must call them yourself
 * from your test case.
 * 
 * <p>
 * <i>Do not call from your setUp() method. You must call this method from
 * each of your test methods.</i>
 * 
 * @param arguments
 *            The Bundle as if supplied to
 *            {@link android.support.v4.Fragment#setArguments(Bundle)}.
 * @param savedInstanceState
 *            The instance state, if you are simulating this part of the
 *            life cycle. Typically null.
 * @param lastNonConfigurationInstance
 *            This Object will be available to the Activity if it calls
 *            {@link android.app.Activity#getLastNonConfigurationInstance()}
 *            . Typically null.
 * @return Returns the Fragment that was created
