如何在 Android Studio 中使用 android.test.mock [英] How to use android.test.mock in Android Studio

问题描述

我正在尝试在单元中使用 MockContext在 Android Studio 中对 Android 项目进行测试.问题是，包 android.test.* 在项目中不可见.

我不确定应该向 Gradle 添加什么才能导入它.我尝试了 com.android.support.test:rules:1.0.2 和 androidx.test:rules:1.1.1 (IDE 提出的建议之一)，但是这不是我要找的.

build.gradle:

应用插件:'com.android.application'安卓 {compileSdkVersion 28默认配置{applicationIdcom.myApp"minSdk 版本 23目标SDK版本28版本代码 1版本名称1.0"testInstrumentationRunnerandroid.support.test.runner.AndroidJUnitRunner"}构建类型{释放 {minifyEnabled falseproguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'}}}依赖{实现文件树(目录:'libs'，包括:['*.jar'])//不检查GradleCompatible实现 'com.android.support:appcompat-v7:28.0.0'实现 'com.android.support:design:28.0.0'实现 'com.android.support.constraint:constraint-layout:1.1.3'testImplementation 'junit:junit:4.12'androidTestImplementation 'com.android.support.test:runner:1.0.2'androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'实现 'com.google.firebase:firebase-core:16.0.8'实现 'com.android.support:recyclerview-v7:28.0.0'testImplementation 'com.android.support.test:rules:1.0.2'}应用插件:'com.google.gms.google-services'

编译时报错:

<块引用>

错误:android.test.mock 包不存在

我应该向 gradle 添加什么才能访问 android.test 包?

解决方案

实际上，您可以从单元测试中访问 android.test.mock 并获得对 MockContext 班级.对于 AndroidX 项目，您可以在应用模块的 build.gradle 中添加以下内容:

android {...useLibrary 'android.test.mock'}

I'm trying to use MockContext in unit tests for Android projects in Android Studio. The problem is, package android.test.* is not visible in the project.

I'm not sure what should I add to Gradle in order to import it. I tried com.android.support.test:rules:1.0.2 and androidx.test:rules:1.1.1 (one of the suggestions made by IDE), but that's not the one I'm looking for.

build.gradle:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.myApp"
        minSdkVersion 23
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    //noinspection GradleCompatible
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support:design:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    implementation 'com.google.firebase:firebase-core:16.0.8'
    implementation 'com.android.support:recyclerview-v7:28.0.0'
    testImplementation 'com.android.support.test:rules:1.0.2'
}

apply plugin: 'com.google.gms.google-services'

Error message when compiling:

error: package android.test.mock does not exist

What should I add to gradle to have access to android.test packages?

解决方案

Actually, you can access android.test.mock from your unit tests and gain access to the MockContext class. For AndroidX projects, you can add the following in your app module's build.gradle:

android {
    ...
    useLibrary 'android.test.mock'
}
