用robolectric运行单元测试get Resources $ NotFoundException

Question

The offical demo can't run correctly. When I run the unit test demo, it show android.content.res.Resources$NotFoundException: String resource ID #0x7f050000 in the consle.

As the reason of network , I can't use m2e to create my project. But I download all the needed .jar with maven on another computer and copy the to this one, then add them into Eclipse IDE Java Build Path --> Library

And here is my source code:

public class MainActivity extends Activity {
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    View button = findViewById(R.id.login);
    button.setOnClickListener(new View.OnClickListener() {
      public void onClick(View view) {
        startActivity(new Intent(MainActivity.this, LoginActivity.class));
      }
    });
  }
}

and the test code are as follow:

@RunWith(MyRunner.class)
public class MainActivityTest {
  @Test
  public void onCreateShouldInflateTheMenu() {
  Activity activity = Robolectric.setupActivity(MainActivity.class);

  final Menu menu = shadowOf(activity).getOptionsMenu();
  assertEquals("First menu item", menu.findItem(R.id.item1).getTitle());
  assertEquals("Second menu item", menu.findItem(R.id.item2).getTitle());
}

When I run the testcase with junit test, they following error info are shows in the "failure trace":

I also tried to override the RobolectricTestRunner and add the @Config tag, but it's the same result. How can I fix the problem and run the demo successfully?

Answer 1

您必须在build.gradle模块配置中将testOptions {unitTests {includeAndroidResources = true}}添加到a​​ndroid

Answer 2

It worked for me:

android {
    ...
    testOptions {
        unitTests { includeAndroidResources = true }
    }
}
