java.lang.RuntimeException：缺少从 @HiltAndroidTest 生成的 Hilt 类

Question

我正在尝试运行使用 Hilt 进行简单的 Robolectric 测试。

@HiltAndroidTest
@Config(application = HiltTestApplication::class)
@RunWith(AndroidJUnit4::class)
class SplashActivityTest2 {

    @get:Rule
    var hiltRule = HiltAndroidRule(this)

    @Test
    fun fooTest() {
        val splashActivity = ActivityScenario.launch(SplashActivity::class.java)
    }
}

但是当我尝试运行使用 Android Studio 进行测试时，我得到

java.lang.RuntimeException: Hilt classes generated from @HiltAndroidTest are missing. Check that you have annotated your test class with @HiltAndroidTest and that the processor is running over your test

这是完整的堆栈跟踪。

[Robolectric] com.theapache64.nemo.feature.splash.SplashActivityTest2.fooTest: sdk=28; resources=BINARY
Called loadFromPath(/system/framework/framework-res.apk, true); mode=binary sdk=28

这是我的 app/build.gradle

具有纯 instrumentationTest (androidTest) 的同一文件仍然有效。

你错过了这个

kaptTest 'com.google.dagger:hilt-android-compiler:2.28-alpha'

来自您的依赖项..

来源：https://developer.android.com/training/dependency-injection/hilt-testing

dependencies {
    // For Robolectric tests.
    testImplementation 'com.google.dagger:hilt-android-testing:2.28-alpha'
    // ...with Kotlin.
     kaptTest 'com.google.dagger:hilt-android-compiler:2.28-alpha'
    // ...with Java.
    testAnnotationProcessor 'com.google.dagger:hilt-android-compiler:2.28-alpha'

    // For instrumented tests.
    androidTestImplementation 'com.google.dagger:hilt-android-testing:2.28-alpha'

}

Answer 2

使匕首柄与 Robolectric 正常工作。请确保您具备以下条件：

从您的依赖项中获得 kaptTest 'com.google.dagger:hilt-android-compiler:...'。
在你的测试中有 @HiltAndroidTest class。
在您的测试 class 中有 @Config(application = HiltTestApplication::class) 或在 robolectric.properties 文件中指定要使用的应用程序： application=dagger.hilt.android.testing.HiltTestApplication
