Question

我无法使用Robolectric配置我的Android Studio项目。任何人都可以一步一步地指导我使用Robolectric 2.4＆amp; amp;来构建一个android studio 1.1.0项目。 gradle 2.2.1

此示例项目工作正常https://github.com/robolectric/deckard-gradle。但我无法在现有的Android Studio项目中实现它。

//下面是详细说明

//项目build.gradle的内容

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.1.0'
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

// app / src / build.gradle的内容

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "robo.testing.android.testrobo08"
        minSdkVersion 16
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    sourceSets { main { java.srcDirs = ['src/main/java'] } }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:21.0.3'

    // Test Compile
    testCompile 'junit:junit:4.12'
    testCompile 'org.robolectric:robolectric:2.4'
    testCompile "org.mockito:mockito-core:1.9.5"
}

// MainActivityTest的内容

    public void testTextView_lableName() throws Exception {
        String actual = textView.getText().toString();

我找到了一些解决方案的参考资料 https://github.com/robolectric/robolectric/issues/1592
@erd如果您使用的是Gradle / Android Studio，则需要创建一个自定义测试运行器，告诉Robolectric在哪里可以找到合并的资源，资源和清单。请参阅此处的讨论：

src / test / java / packageName.test / CustomRobolectricRunner.java的内容

 public CustomRobolectricRunner(Class<?> testClass)
            throws InitializationError {
        super(testClass);
        String buildVariant = (BuildConfig.FLAVOR.isEmpty()
                ? "" : BuildConfig.FLAVOR+ "/") + BuildConfig.BUILD_TYPE;
        String intermediatesPath = BuildConfig.class.getResource("")
                .toString().replace("file:", "");
        intermediatesPath = intermediatesPath
                .substring(0, intermediatesPath.indexOf("/classes"));

        System.setProperty("android.package", 
                BuildConfig.APPLICATION_ID);
        System.setProperty("android.manifest",
                intermediatesPath + "/manifests/full/"

    }
