android.content.res.Resources$NotFoundException : no such label

Question

当我尝试使用 Robolectric-rc2 并运行以下测试时，我得到了 no such android.content.res.Resources$NotFoundException: no such label com.yourapp.android:string/app_name。我尝试从运行自定义运行和使用构建 Activity 而不是安装 Activity 的 manifest.xml 文件中删除字符串。有任何想法吗？

@RunWith(TestRunner.class)
public class MainActivityTest {
private MainActivity mainActivity;

@Before
public void setUp() throws Exception {
    mainActivity = Robolectric.setupActivity(MainActivity.class);

}

@Test
public void textTest() throws Exception {
    TextView textView = (TextView) mainActivity.findViewById(R.id.daily_text);
    assertEquals(textView, "com.yourapp.android");
    assertThat(textView).isNotNull();
}}

我的 gradle 文件看起来像这样，我删除了一些库。

    resolutionStrategy {
        force 'org.hamcrest:hamcrest-core:1.3'

我已经通过使用 Robolectrci 3.0rc3 修复了这个问题，并将以下声明添加到我的所有 unitTest 类中

@Config(constants = BuildConfig.class, sdk = 21)
@RunWith(RobolectricGradleTestRunner.class)
public class SomeRandomTest
{
...
}
