1.robolectric フレームワークを使用してフラグメントをテストしたい.私は android-support-v4.jar を使用しています。NewFragment クラスの onCreateView() メソッドが呼び出されません。
================================================== =========
@RunWith(RobolectricTestRunner.class)
public class NewFragmentTest extends Fragment{
private NewFragment newFragment;
public void startFragment(Fragment fragment) {
FragmentActivity activity=Robolectric.buildActivity(FragmentActivity.class).create().start().resume().get();
FragmentManager fragmentManager = activity
.getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager
.beginTransaction();
fragmentTransaction.replace(R.id.content_frame,fragment,
"new fragment");
//fragmentTransaction.add(fragment, "");
// fragmentTransaction.commit();
}
@Before
public void setUp() throws Exception {
newFragment = new NewFragment();
newFragment.onCreate(null);
startFragment(newFragment);
}
@Test
public void testFragmentNotNull() {
Assert.assertNotNull(newFragment);
}
@Test
public void shouldHaveButton() throws Exception {
TextView textview = (TextView) getView().findViewById(R.id.id_txt);
assertThat(textview.getVisibility(), equalTo(View.VISIBLE));
}
}
When i am running tests its giving below exception.
java.lang.NullPointerException
