Roboelectric:java.lang.RuntimeException: Stub

I am getting "java.lang.RuntimeException: Stub!" when running the roboelectric tests.I have proper eclipse ordering and also set the runner properly. Here's the stack trace.

here is my test

  package com.example.sample.test;

import static org.hamcrest.CoreMatchers.equalTo;
import static org.junit.Assert.assertThat;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.robolectric.Robolectric;
import org.robolectric.RobolectricTestRunner;

import com.example.sample.MainActivity;
import com.example.sample.R;

@RunWith(RobolectricTestRunner.class)
public class MyActivityTest {
    private MainActivity activity;

    @Test
    public void shouldHaveHappySmiles() throws Exception {
        String hello = new MainActivity().getResources().getString(R.string.hello_world);
        assertThat(hello, equalTo("Hello world!"));
        activity = Robolectric.buildActivity(MainActivity.class)
                .create().get();
    }
}

I wrote this testcase just to hang around with Roboelectric.

You shouldn't do :

new MainActivity().getResources().getString(R.string.hello_world);

This is probably where the Stub! exception comes from, although it's not clear in the stack trace.

Instead, create your activity with Robolectric, then get the value of the hello string, then assert:

activity = Robolectric.buildActivity(MainActivity.class).create().start().resume().visible().get();
String hello = Robolectric.shadowOf(activity).getResources().getString(R.string.hello_world);
assertThat(hello, equalTo("Hello world!"));

You can also use ShadowApplication#getResources().
