DaggerTestAppComponent 未在 Android 测试目录中生成

Question

我正在为 DI 使用 dagger android。我正在尝试通过将 Viewmodel 注入我的测试类（在测试目录中）来测试它。但是没有生成 DaggerTestAppComponent。

应用组件：-

@Component(
    modules = [
        AndroidSupportInjectionModule::class,
        ActivityBinder::class,
        DataBaseBinder::class,
        NetworkBinder::class,
        RoomBinder::class,
        ViewModelBinder::class,
        UseCasesBinder::class,
        DataSourceBinder::class,
        ServiceBinder::class
    ]
)
interface AppComponent : AndroidInjector<ZeniusApp> {

    @Component.Builder
    interface Builder {

        @BindsInstance
        fun application(application: Application): Builder

        fun build(): AppComponent
    }
}

DaggerTestAppComponent 没有生成

Answer 1

我相信您忘记在 androidTest 构建变体上运行 dagger-compiler 注释处理器。由于您似乎在使用 Kotlin，因此您需要添加以下内容：

androidTestImplementation "com.google.dagger:dagger:2.32"
kaptAndroidTest "com.google.dagger:dagger-compiler:2.32"

到您的build.gradle 的依赖项块中（只需替换为您使用的匕首版本）。默认注释处理器不会为您的测试和 android 测试构建变体生成任何代码（它们不会在构建期间执行）。
