当项目包含多个android模块时，不会生成匕首测试组件

Question

Android Studio 3.4
kotlin 1.3.0
dagger 2.21

我有一个项目有一个presentation和data模块。我正在尝试在数据模块中创建测试组件。我可以为演示模块生成组件。我正在使用kotlin-kts进行gradle构建。

对于演示模块，我有以下qazxsw poi

build.gradle.kts

对于演示模块，我有以下应用程序：

plugins {
    id("com.android.application")
    kotlin("android")
    kotlin("kapt")
}

android {
    compileSdkVersion(Versions.compileSdkVersion)

    defaultConfig {
        applicationId = "nz.org.westforce.mobileui"
        minSdkVersion(Versions.minSdkVersion)
        targetSdkVersion(Versions.targetSdkVersion)
        versionCode = Versions.versionCode
        versionName = Versions.versionName

        testInstrumentationRunner = "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        getByName("release") {
            isMinifyEnabled = true
            proguardFiles(getDefaultProguardFile("proguard-android-optimize.txt"), "proguard-rules.pro")
        }
    }
}

dependencies {
    implementation(Libraries.appCompat)
    implementation(Libraries.kotlinStdlib)
    implementation(Libraries.daggerAndroid)
    implementation(Libraries.daggerSupport)
    kapt(Libraries.daggerCompiler)
    kapt(Libraries.daggerProcessor)

    androidTestImplementation(TestLibraries.runner)
    androidTestImplementation(TestLibraries.espressoCore)

    testImplementation(TestLibraries.junit)
    testImplementation(Libraries.daggerAndroid)
    testImplementation(Libraries.daggerSupport)

    kaptTest(Libraries.daggerCompiler)
    kaptTest(Libraries.daggerProcessor)

    implementation(project(":data"))
}

组件

class WestforceCreditUnionMobileuiApplication
    : Application(), HasActivityInjector {

    @Inject
    lateinit var dispatchingAndroidActivityInjector: DispatchingAndroidInjector<Activity>

    override fun onCreate() {
        super.onCreate()

        DaggerWestforceCreditUnionMobileuiComponent.builder()
            .application(this)
            .build()
            .inject(this)
    }

    override fun activityInjector(): AndroidInjector<Activity> =
        dispatchingAndroidActivityInjector
}

以上是有效的，生成了

@Singleton
@Component(modules = [AndroidSupportInjectionModule::class])
interface WestforceCreditUnionMobileuiComponent {
    @Component.Builder
    interface Builder {
        @BindsInstance
        fun application(application: WestforceCreditUnionMobileuiApplication): Builder

        fun build(): WestforceCreditUnionMobileuiComponent
    }

    fun inject(application: WestforceCreditUnionMobileuiApplication)
}

现在在我的DaggerWestforceCreditUnionMobileuiComponent模块中，我可以尝试创建一个测试组件，但是dagger不会生成测试组件类。

我在data目录中有以下测试组件

java/test/package/di

在我的测试课上：

@Singleton
@Component(modules = [TestNetworkModule::class])
interface TestWestforceCeditUnionComponent {
    fun inject(webServicesImpTest: WebServicesImpTest)
}

我没有在这里指定模块，因为它会在这里夸大代码。

对于数据模块中的build.gradle.kts：

class WebServicesImpTest {

    @Inject
    private lateinit var webServicesImp: WebServicesImp

    @Test
    fun setUp() {
        /* the DaggerTestWestforceCreditUnionComponent is not generated */
    }
}

我使用以下dagger.android依赖项：

import org.gradle.kotlin.dsl.implementation

plugins {
    id("com.android.library")
    id("kotlin-android")
}

android {
    compileSdkVersion(Versions.compileSdkVersion)

    defaultConfig {
        minSdkVersion(Versions.minSdkVersion)
        targetSdkVersion(Versions.targetSdkVersion)
        versionCode = Versions.versionCode
        versionName = Versions.versionName

        testInstrumentationRunner = "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        getByName("release") {
            isMinifyEnabled = true
            proguardFiles(getDefaultProguardFile("proguard-android-optimize.txt"), "proguard-rules.pro")
        }
    }
}

dependencies {
    implementation(Libraries.kotlinStdlib)
    implementation(Libraries.appCompat)
    implementation(Libraries.daggerAndroid)
    implementation(Libraries.daggerSupport)
    kapt(Libraries.daggerCompiler)
    kapt(Libraries.daggerProcessor)

    testImplementation(TestLibraries.junit)
    testImplementation(TestLibraries.assertJ)
    testImplementation(TestLibraries.mockitoKotlin)

    testImplementation(Libraries.daggerAndroid)
    testImplementation(Libraries.daggerSupport)
    kaptTest(Libraries.daggerCompiler)
    kaptTest(Libraries.daggerProcessor)
}

我尝试重建项目并尝试运行以下任务

  const val daggerAndroid = "com.google.dagger:dagger-android:${Versions.daggerAndroidVersion}"
  const val daggerCompiler = "com.google.dagger:dagger-compiler:${Versions.daggerAndroidVersion}"
  const val daggerProcessor = "com.google.dagger:dagger-android-processor:${Versions.daggerAndroidVersion}"
  const val daggerSupport = "com.google.dagger:dagger-android-support:${Versions.daggerAndroidVersion}"

一切都建立成功，

有人认为我在考虑使用不同的android模块，也许数据模块无法在演示模块中看到compileDebugUnitTestSources。

非常感谢任何建议

你忘了添加

WestforceCreditUnionMobileuiApplication

到kotlin("kapt") 模块build.gradle.kts中的plugins部分。

然后Gradle继续为你的:data错过@Provides。另外你应该修复缺少的WebServicesImp提供程序，在我的例子中我刚刚删除了Context使用。这应该添加到Context：

TestNetworkModule

之后，

@Singleton
@Provides
fun provideRetrofit(okHttpClient: OkHttpClient): Retrofit {
    return Retrofit.Builder()
        .baseUrl("http://www.holidaywebservice.com")
        .client(okHttpClient)
        .addConverterFactory(SimpleXmlConverterFactory.createNonStrict(Persister(AnnotationStrategy())))
        .build()
}
@Reusable
@Provides
fun provideWebServices(retrofit: Retrofit): WebServices {
    return retrofit.create(WebServices::class.java)
}

@Reusable
@Provides
fun provideWebServicesImp(webServices : WebServices): WebServicesImp {
    return WebServicesImp(webServices)
}

成功生成。
