How can I test fragments with Robolectric?

Question

I know there is a Robolectric.shadowOf(Fragment) method and a ShadowFragment class, thought they aren\'t listed on the docs, but I can\'t make it w

Support fragments have been moved to module:

shadows-support-v4

(as of July,2015, Robolectric v3.0)

Add a gradle dependency to app/build.gradle:

testCompile 'org.robolectric:shadows-support-v4:3.0'

Then import to your Robolectric test java class:

import org.robolectric.shadows.support.v4.SupportFragmentTestUtil;

Then you can start & use a support-v4 fragment for testing:

@Test
public void minimalFragmentTest() throws Exception {
    MyFunFragment fragment = new MyFunFragment();
    SupportFragmentTestUtil.startVisibleFragment(fragment);
    assertThat(fragment.getView()).isNotNull();
}
