运行摇篮测试与NullPointerException异常

Robolectric和程序兼容性结果正如标题所说运行Robolectric测试与摇篮导致NullPointerException同时呼吁Robolectric.buildActivity(MyActivity.class).create().get();运行摇篮测试与NullPointerException异常

的build.gradle（基于this answer）

buildscript { 
    repositories { 
     mavenCentral() 
    } 
    dependencies { 
     classpath 'com.android.tools.build:gradle:0.5.+' 
    } 
} 

repositories { 
    mavenCentral() 
    maven { 
     url 'https://oss.sonatype.org/content/repositories/snapshots/' 
    } 
} 

apply plugin: 'android' 

android { 
    compileSdkVersion 18 
    buildToolsVersion "18.0.1" 

    defaultConfig { 
     minSdkVersion 7 
     targetSdkVersion 16 
    } 
} 

sourceSets { 
    testLocal { 
     java.srcDir file('src/test/java') 
     resources.srcDir file('src/test/resources') 
    } 
} 

dependencies { 
    compile 'com.android.support:support-v4:18.0.0' 
    compile 'com.android.support:appcompat-v7:18.0.+' 
    compile project(':Libraries:ViewPagerIndicator') 

    testLocalCompile project(':Libraries:appcompat') 
    testLocalCompile 'junit:junit:4.8.2' 
    testLocalCompile 'org.robolectric:robolectric:2.1' 
    testLocalCompile 'com.google.android:android:4.1.1.4' 
    testLocalCompile 'com.google.android:support-v4:r6' 
    testLocalCompile 'org.roboguice:roboguice:2.0' 
} 

task localTest(type: Test, dependsOn: assemble) { 
    testClassesDir = sourceSets.testLocal.output.classesDir 

    android.sourceSets.main.java.srcDirs.each { dir -> 
     def buildDir = dir.getAbsolutePath().split('/') 
     buildDir = (buildDir[0..(buildDir.length - 4)] + ['build', 'classes', 'debug']).join('/') 

     sourceSets.testLocal.compileClasspath += files(buildDir) 
     sourceSets.testLocal.runtimeClasspath += files(buildDir) 
    } 

    classpath = sourceSets.testLocal.runtimeClasspath 
} 

check.dependsOn localTest

MyActivityTest.java

@RunWith(RobolectricTestRunner.class) 
@Config(manifest=Config.NONE) 
public class MyActivityTest { 

    MyActivity activity; 


    @Before 
    public void setUp() { 
     activity = Robolectric.buildActivity(MyActivity.class).create().get(); 
    } 

    @Test 
    public void testSomeNumber() { 
     Assert.assertEquals(true,true); 
    } 
}

MyActivity.java延伸，其延伸ActionBarActivity

运行命令行这种配置主叫./gradlew localTest结果在下面的例外

任何想法一个BaseActivity？

好像问题出在MyActivity – Selvin

是啊，好像是。但该行只是调用'super.onCreate（savedInstanceState）;'与BaseActivity相同，在此之前我不会调用任何东西。 – dng

我不确定，但从文档'Config.NONE'如果你不使用资源或项目没有清单。但这两种情况都不适用于活动测试 –

尝试更改您的构建脚本。当你执行构建任务时，gradle文件下面会自动运行robolectric测试。您可以根据需要编辑它。我们不得不使用快照版本。更多详细信息：gradle-android-test-plugin

测试的默认路径是

的src /测试/ JAVA/...

buildscript { 
    repositories { 
    mavenCentral() 
    maven { 
     url 'https://oss.sonatype.org/content/repositories/snapshots/' 
    } 
    } 
    dependencies { 
    classpath 'com.android.tools.build:gradle:0.6.+' 
    classpath 'com.squareup.gradle:gradle-android-test-plugin:0.9.1-SNAPSHOT' 

    } 
} 
apply plugin: 'android' 
apply plugin: 'android-test' 

repositories { 
mavenCentral() 
} 

android { 
compileSdkVersion 19 
buildToolsVersion "19.0.0" 

defaultConfig { 
    minSdkVersion 8 
    targetSdkVersion 19  
} 
} 

dependencies { 
    compile 'com.android.support:appcompat-v7:+' 
    testCompile 'junit:junit:4.10' 
    testCompile 'org.robolectric:robolectric:2.1.+' 
    testCompile 'com.squareup:fest-android:1.0.+' 
}
