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;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 {

jcenter()

解决方法
我发现了问题.在我的情况下,它无法找到AndroidManifest.xml文件&我没有使用customRobolectricTestRunner.
项目结构
Gradle Version 2.2.1 Android Plugin Version 1.1.0
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:1.1.0'
}
}
allprojects {
repositories {
jcenter()
}
}
apply plugin: 'com.android.application'
android {
compileSdkVersion 21
buildToolsVersion "21.1.2"
defaultConfig {
applicationId "robo.testing.android.testrobo"
minSdkVersion 16
targetSdkVersion 18
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'),include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.3'
// Test Compile
testCompile 'junit:junit:4.12'
testCompile 'org.robolectric:robolectric:2.4'

}

我找到了一些解决方案的参考资料

@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.请看这里的讨论：
http://nenick-android.blogspot.in/2015/03/android-studio-110-and-robolectric-30.html
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/"
+ buildVariant + "/AndroidManifest.xml");
System.setProperty("android.resources",intermediatesPath + "/res/" + buildVariant);
System.setProperty("android.assets",intermediatesPath + "/assets/" + buildVariant);
}
