Robolectric：IllegalStateException：您需要在此活动中使用 Theme.AppCompat 主题（或后代）

Question

我是 Robolectric 和 Android 上的一般仪器测试的新手。 我跟着guide for Robolectric 测试我的第一个测试。 但是我得到了：

java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.

我搜索了错误，但没有解决方案有帮助。我将所有可能导致此错误的内容都包括在内。

Answer 1

试试这个： 将您的 Android 清单文件更改为：

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/Theme.AppCompat" >
    <activity
        android:name=".ui.MainActivity"
        android:label="@string/title">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

Answer 2

这是 Robotelectric 的一个错误，这里有一个解决方法：

Android Lolipop Appcompat problems running with Robolectric

您也可以尝试升级到 Robotelectric 3.0 以检查此问题是否已修复。

Answer 3

只需使用@RunWith(RobolectricTestRunner.class) 并快乐

@RunWith(RobolectricTestRunner.class)
public class MainActivityTest {

    @Test
    public void myTest() throws Exception {
        assertEquals(true, true);
    }
}

在此处查看更多信息：http://robolectric.org/getting-started/

Answer 4

您应该改用 RobolectricGradleTestRunner。

import org.robolectric.RobolectricGradleTestRunner;

@RunWith(RobolectricGradleTestRunner.class)
@Config(constants = BuildConfig.class, manifest = Config.NONE)
public class MainActivityRoboTest {

它解决了我的问题。

Answer 5

我刚刚解决了同样的问题，我的解决方法是：

创建一个虚拟应用程序并在 onCreate() 中设置主题：

public class TestApplication extends Application {

    @Override
    public void onCreate() {
        super.onCreate();
        setTheme(R.style.AppTheme); //or just R.style.Theme_AppCompat
    }
}

然后在测试中你在 config 中指定应用程序类：

@RunWith(RobolectricTestRunner.class)
@Config(application = TestApplication.class)
public class YourActivityTest {
    //tests
}

Answer 6

当我想启动一个布局中包含 appBar 的片段时，我遇到了这个问题。

以下方法对我有用。

        launchFragmentInContainer<ProfileSettingsFragment>(themeResId = R.style.AppTheme).moveToState(Lifecycle.State.RESUMED)

Answer 7

如果活动中存在使用该上下文的组件，另一种解决方案是获取 Robolectric 上下文对象，并将其主题设置为 AppCompat。这是单元测试中的 Kotlin 代码示例：

 val context: Context = ApplicationProvider.getApplicationContext()
 context.setTheme(R.style.your_theme_extending_AppCompat_Theme)
 // Use this context throughout the test.


 

Answer 8

在某些情况下需要手动设置主题。

@RunWith(RobolectricTestRunner::class)
class YourClassTest {
    private val activity: Activity = Robolectric.buildActivity(Activity::class.java).create().get()

    @Before
    fun setupTheme() {
        activity.setTheme(R.style.Theme_MaterialComponents_Light)
    }
}

如果您要测试依赖于主题的 customView/组件，请记住仅在将主题分配给活动后才实例化它

@RunWith(RobolectricTestRunner::class)
class YourClassTest {
    private val activity: Activity = Robolectric.buildActivity(Activity::class.java).create().get()
    private lateinit var yourCustomComponent: YourCustomComponent

    @Before
    fun setupTheme() {
        activity.setTheme(R.style.Theme_MaterialComponents_Light)
        yourCustomComponent = YourCustomComponent(activity)
    }
}
