Android Studio 3.0 Beta2
classpath 'com.android.tools.build:gradle:3.0.0-beta3'
testCompile 'org.robolectric:robolectric:3.4.2'

我正在使用的测试类无法运行:

@Config(constants = BuildConfig.class, sdk = Build.VERSION_CODES.LOLLIPOP)
@RunWith(RobolectricTestRunner.class)
public class RecipeAdapterTest {
    private MainActivity activity;

    @Before
    public void setup() {

    activity = Robolectric.setupActivity(MainActivity.class);

    /* Also tried this same Error
     activity = Robolectric.buildActivity(MainActivity)
                .create()
                .resume()
                .get();
    */
    }

    @Test
    public void testActivityShouldNotBeNull() {
        assertThat(activity, is(notNullValue()));
    }
}

这是错误的堆栈跟踪:

android.content.res.Resources$NotFoundException: String resource ID #0x7f0c0020

    at android.content.res.Resources.getString(Resources.java:360)

    at org.robolectric.Robolectric.setupActivity(Robolectric.java:102) …

我刚刚用一个新应用程序设置了Roboelectric 3.2.2,我已经编写了我的第一个简单测试:

@RunWith(RobolectricTestRunner.class)
@Config(manifest="src/main/AndroidManifest.xml",
    packageName="my.pacakge.name.debug")
public class MainActivityTest {

    @Test
    public void clickButton() {
        MainActivity mainActivity = Robolectric.setupActivity(MainActivity.class);
        String text = ((TextView)mainActivity.findViewById(R.id.text_main)).getText().toString();
        assertEquals("Should equal Hello World!", "Hello World!", text);
    }
}

我已经照着所有的设置和说明这里和这里,但我仍然得到这个错误每次我尝试运行测试时间:

android.content.res.Resources$NotFoundException: Unable to find resource ID #0x0 in packages [android, my.package.name.debug]

此异常发生在我正在调用的测试的第一行setupActivity().
