为Robolectric测试导入正确的AssertThat方法

Question

我正在尝试从Robolectric.org的Writing Your First Test页面进行测试.有问题的测试看起来像这样:

  @Test
  public void clickingLogin_shouldStartLoginActivity() {
    WelcomeActivity activity = Robolectric.setupActivity(WelcomeActivity.class);
    activity.findViewById(R.id.login).performClick();

    Intent expectedIntent = new Intent(activity, WelcomeActivity.class);
    assertThat(shadowOf(activity).getNextStartedActivity()).isEqualTo(expectedIntent);
  }

我得到这个编译错误:Cannot resolve method 'assertThat(android.content.Intent).

我看到用于导入此方法的两种可能性是,org.hamcrest.MatcherAssert.assertThat并且org.junit.Assert.assertThat,这两种方法都没有assertThat像本Robolectric测试中使用的单参数方法.

我的应用程序build.gradle有这些依赖项:

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:23.1.0'
    compile 'com.android.support:design:23.1.0'

    testCompile "org.robolectric:robolectric:3.0"
    testCompile 'junit:junit:4.12'
}

这个测试使用什么框架/库？

这既不是junit或hamcrest断言API.我认为它是Android AssertJ或只是AssertJ:

testCompile 'org.assertj:assertj-core:1.7.1'
