使用Robolectric进行DialogFragment测试

我希望测试一个dialog Fragment是否在使用Roboelectric时显示出来。

public class SomeDialogActivity extends FragmentActivity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        DialogFragment someDialogFragment = new SomeDialogFragment();
        someDialogFragment.show(getSupportFragmentManager(), "some_dialog");
    }
}

现在我想测试一下是否会出现这个对话框，就像这样：

@Test
public void dialogFragmentIsShownToTheUser() {
        DialogFragment dialog = new SomeDialogFragment();
        DialogFragment someDialogFragment = new SomeDialogFragment();
        startFragment(someDialogFragment);

        SomeDialogActivity activity = Robolectric.setupActivity(SomeDialogActivity.class);

        Dialog dialog = ShadowDialog.getLatestDialog();
        assertNotNull(dialog);
        assertEquals(.... , ....)
}

将其视为常规的片段情况。因此，要检查片段是否显示，您需要编写以下代码：

@Test
public void dialogFragmentIsShownToTheUser() {
    SomeDialogActivity activity = Robolectric.setupActivity(SomeDialogActivity.class);

    DialogFragment dialogFragment = (DialogFragment) activity.getSupporFragmetManager()
                                       .findFragmentByTag("some_dialog");
    assertNotNull(dialogFragment);
}
