模拟Robolectric中菜单项的单击

Question

在Robolectric中模拟按钮单击非常简单:

Button someButton = (Button) findViewById(R.id.some_button);
someButton.performClick();

但是,我似乎无法弄清楚如何用菜单项做同样的事情.我创建了一个菜单Activity.onCreateOptionsMenu,如何模拟其中一个项目的点击？

Answer 1

MenuItem item = new TestMenuItem() {
  public int getItemId() {
    return R.id.hello;
  }
};

activity.onOptionsItemSelected(item);

ShadowActivity shadowActivity = Robolectric.shadowOf(activity);
Intent startedIntent = shadowActivity.getNextStartedActivity();
ShadowIntent shadowIntent = Robolectric.shadowOf(startedIntent);

assertThat(shadowIntent.getComponent().getClassName(), equalTo(HelloActivity_.class.getName()));

请享用!

Answer 2

在Robolectric 3.0+中,您可以使用ShadowActivity.clickMenuItem(menuItemResId):

        // Get shadow
    ShadowActivity shadowActivity = Shadows.shadowOf(activity);

    // Click menu
    shadowActivity.clickMenuItem(R.id.settings_option_item);

    // Get intent
    Intent startedIntent = shadowActivity.getNextStartedActivity();
    ShadowIntent shadowIntent = Shadows.shadowOf(startedIntent);

// Make your assertion
assertThat(shadowIntent.getComponent().getClassName(), equalTo(HelloActivity_.class.getName()));
