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);
  }

我收到此编译错误：Cannot resolve method 'assertThat(android.content.Intent)。

我看到导入此方法的两种可能性是org.hamcrest.MatcherAssert.assertThat和org.junit.Assert.assertThat，它们都没有像本Robolectric测试中使用的单参数assertThat方法。

我的应用build.gradle有这些依赖关系：

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'
}

此测试使用什么框架/库？

Answer 1

It is neither junit or hamcrest assertion API. I think it is Android AssertJ or just AssertJ:

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

Answer 2

按照以下说明，问题应该消失。将第一行放在gradle构建文件中

testCompile 'org.mockito:mockito-core:1.9.5'
testCompile 'junit:junit:4.12'

import org.junit.Test;
import static org.hamcrest.CoreMatchers.is;
import static org.hamcrest.MatcherAssert.assertThat;

public class SomethingTest {
     @Test
     public void testSomething() {
           assertThat(true, 1>1); 
     }
}
