Robolectric中的资源NotFoundException

Question

Since I migrated a project to Android Studio, I am getting following error when I want to run my tests:

Process finished with exit code 255

My testclass looks like this:

@Config(manifest = C.MANIFEST, emulateSdk = 18, reportSdk = 18)
@RunWith(RobolectricTestRunner.class)
public class JSONDataHelperTest {...}

Any ideas?

================ MORE INFO ==================

I am using

• Android Studio 1.1 Beta 4
• Roboletric 2.4
• com.android.tools.build:gradle:1.0.1
• com.github.jcandksolutions.gradle:android-unit-test:2.1.1
• org.robolectric:robolectric-gradle-plugin:0.12.+

My project structure (modules):

1. app: main app
2. robolectric-tests: testing classes

My robolectric-tests build.gradle:

evaluationDependsOn(':app')
apply plugin: 'java'

repositories {
    mavenCentral()

    def androidHome = System.getenv("ANDROID_HOME")
    // check that androidHome points to the android home dir
    println("android home dir: "+androidHome)

    maven {
        url "$androidHome/extras/android/m2repository/"
    }
}


dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])

    def androidModule = project(':app')
    compile androidModule

    println "androidModule classpath: "+androidModule.android.applicationVariants.toList().first().javaCompile.classpath
    testCompile androidModule.android.applicationVariants.toList().first().javaCompile.classpath
    testCompile androidModule.android.applicationVariants.toList().first().javaCompile.outputs.files
    testCompile files(androidModule.plugins.findPlugin("com.android.application").getBootClasspath())

    //testCompile 'junit:junit:4.12-beta-2'
    testCompile 'org.robolectric:robolectric:2.4'
    testCompile 'org.mockito:mockito-core:1.10.8'
    testCompile 'org.assertj:assertj-core:1.7.0'
    testCompile 'com.squareup:fest-android:1.0.8'
}



//prevent the "superClassName is empty" error for classes not annotated as tests
tasks.withType(Test) {
    scanForTestClasses = false
    include "**/*Test.class" // whatever Ant pattern matches your test class files
}

Answer 1

The error message looks like that no resources are found ;) explicit the content from your string.xml

Lets start ..

com.github.jcandksolutions.gradle:android-unit-test:2.1.1

This plugin support explicit to have your tests in the same module

• app
  • src/main/java
  • src/test/java

For extra test module you must use a different plugin to support robolectric. You can also have extra test modules with the jcandksolutions plugin but this would be more a application->library relationship instead of test->application/library.

testCompile androidModule.android.applicationVariants.toList().first().javaCompile.classpath testCompile androidModule.android.applicationVariants.toList().first().javaCompile.outputs.files testCompile files(androidModule.plugins.findPlugin("com.android.application").getBootClasspath())

Nice try but I guess this will not give you all classes and resources. This lines aren't necessary eval which plugin you will use.

What now ...

Questions is how should you project structure look? Is it important for you to have tests in a separate module?

With separated test module use https://github.com/novoda/gradle-android-test-plugin . For one module stay with jcandksolutions or you could also try the plugin from robolectric team https://github.com/robolectric/robolectric-gradle-plugin

All plugins have examples how to use them:

• https://github.com/JCAndKSolutions/android-unit-test/tree/master/example
• https://github.com/novoda/gradle-android-test-plugin/tree/master/sample-test
• https://github.com/robolectric/deckard-gradle

For 1.0 version from Android Studio I recommend jcandksolutions, because of much better integration into Android Studio.

With Android Studio 1.1 Beta you can avoid any of this plugins, or use the current master from robolectric team.

Here is a example without plugins https://github.com/nenick/AndroidStudioAndRobolectric and a guide how you do it self step by step http://nenick-android.blogspot.de/2015/02/android-studio-110-beta-4-and.html
