Question

我决定为我正在开发的android应用程序编写一些单元测试。我选择了Robolectric（版本2.3）。我按照我发现here：

的教程做了

@Config(emulateSdk = 18)
@RunWith(RobolectricTestRunner.class)
public class MainTest {

    private Main mainActivity;

    @Before
    public void setup() {
         mainActivity = Robolectric.buildActivity(Main.class).create().get();
    }

    @Test
    public void shouldStartNextActivityWhenOnePlayerButtonWasClicked() throws Exception {
        Button button = (Button) mainActivity.findViewById(R.id.onePlayer);
        button.performClick();
        Intent intent = Robolectric.shadowOf(mainActivity).peekNextStartedActivity();
        assertThat(intent.getComponent().getClassName()).isEqualTo(NextActivity.class.getCanonicalName());
}

在运行测试期间，我遇到以下错误：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.3.2:testCompile (default-testCompile) on project app: Compilation failure
[ERROR] \workspace\app\src\test\java\com\example\app\activity\MainTest.java:[36,35] error: cannot access DownloadManager

表示以下行（shadowOf方法）存在问题：

Intent intent = Robolectric.shadowOf(mainActivity).peekNextStartedActivity();

有人可以解释为什么会出现错误以及如何解决错误吗？也许Robolectric不是我做的最佳选择？

EDITED：我想这个问题可以在我的pom.xml中。我正在使用robolectric（尺寸较小）而不是教程中指出的robolectric-depen-dependencies：
