我正在尝试使用 Robolectric 2.1.1 运行单元测试,但我无法让它膨胀自定义布局(例如 ViewPagerIndicator 类)。假设这是我的布局:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="test"
android:id="@+id/test_test"/>
<com.viewpagerindicator.CirclePageIndicator
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
</LinearLayout>
考虑一下我的测试类:
@RunWith(RobolectricTestRunner.class)
public class TestRoboActivityTest {
private TestRoboActivity mActivity;
@Before
public void setUp() throws Exception {
mActivity = Robolectric.buildActivity(TestRoboActivity.class).create().get();
}
@After
public void tearDown() throws Exception {
mActivity = null;
}
@Test
public void testSanity() throws Exception {
Assert.assertNotNull(mActivity);
}
}
执行“mvn clean test”会导致
测试错误: testSanity(TestRoboActivityTest): XML file .\res\layout\test.xml line #-1(抱歉,尚未实现):错误膨胀类 com.viewpagerindicator.CirclePageIndicator
很酷,所以似乎还不支持自定义视图。检查他们网站上的示例 Robolectric 项目,一种解决方案可能是从 LayoutInflater 中膨胀布局:
@RunWith(RobolectricTestRunner.class)
public class TestRoboActivityTest {
private View mTestRoboActivityView;
@Before
public void setUp() throws Exception {
mTestRoboActivityView = LayoutInflater.from(new Activity()).inflate(R.layout.test, null);
}
@After
public void tearDown() throws Exception {
mTestRoboActivityView = null;
}
@Test
public void testSanity() throws Exception {
Assert.assertNotNull(mTestRoboActivityView);
}
}
这导致:
测试错误: testSanity(TestRoboActivityTest): XML file .\res\layout\test.xml line #-1(抱歉,尚未实现):错误膨胀类 com.viewpagerindicator.CirclePageIndicator
我最后的手段是尝试使用影子类:
@Implements(CirclePageIndicator.class)
public class CirclePageIndicatorShadow implements PageIndicator {
@Override
@Implementation
public void setViewPager(ViewPager view) {
// Stub
}
// etc.
}
并使用@Config(shadows = {CirclePageIndicatorShadow.class})
. 这再次导致
测试错误: testSanity(TestRoboActivityTest): XML file .\res\layout\test.xml line #-1(抱歉,尚未实现):错误膨胀类 com.viewpagerindicator.CirclePageIndicator

请注意,以下 stracktrace 是后来由 David Rabinowitz 添加的。虽然相关,但这不是我当时面临的问题。
这是堆栈跟踪:

你们能指出我正确的方向吗?我没主意了。谢谢。
