无法在包 [android、org.robolectric.default] 中找到资源 ID #0x7f09001c

Question

我正在运行使用 Roboletric 进行一些测试，但我遇到了一个我无法解决的问题。我在运行测试的时候，出现如下错误：

在

com.example.robertoassad.alltestsmerge.MainActivity.onCreate(MainActivity.java:15)

在 MainActivity.java:15 上有以下代码的错误：

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

具体在：setContentView(R.layout.activity_main);

以及

com.example.robertoassad.roboletrictest.MainActivityTest.clickingLogin_shouldStartLoginActivity(MainActivityTest.java:20)

在 MainActivityTest.java:20 上，错误具体在：

MainActivity activity = Robolectric.setupActivity(MainActivity.class);

对我来说，我认为这个问题没有意义...

详情:

测试 class 在文件夹中：app\src\test\java\{package}

测试是：

@RunWith(RobolectricTestRunner.class)
@Config(manifest= Config.NONE)
public class MainActivityTest {

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

        Intent expectedIntent = new Intent(activity, HomeActivity.class);
        Intent actual = ShadowApplication.getInstance().getNextStartedActivity();
        assertEquals(expectedIntent.getComponent(), actual.getComponent());
    }
}

Answer 1

您需要在@Config 中指定清单或常量，以便Robolectric 知道在哪里可以找到资源。 Config.NONE 不会工作。

Answer 2

这对我有用：

前往 Robolectric Setup page 并按照他们的指南移动到最新版本。

换句话说,

添加了截至 2017 年 2 月 17 日的最新版本：testImplementation "org.robolectric:robolectric:3.7.1"
在我的 build.graddle

includeAndroidResources = true

例如，

android {
  testOptions {
    unitTests {
      includeAndroidResources = true
    }
  }
}
dependencies {
    testImplementation "org.robolectric:robolectric:3.7.1"
}

运行我的测试没有任何配置注释

@RunWith(RobolectricTestRunner.class)
public class MyTests {

    @Test
    public void singleTest() {
        //Do and verify or assert something
    }
}
