Impressed by this sample project and how you have all 3 levels of tests working along with Jacoco. I've learned a lot by looking at your code and organization of modules.

One thing I really liked: how you put ComponentTestsRobolectric and UnitTestsRobolectric as folders on the same level as AndroidSample. You did a great job of showing how the build.gradle files in sub folders relate to the master build.gradle file and how Jacoco can point to the directory ../AndroidSample for the code coverage.

However, in AndroidSample you have the src folder with main and test subfolders; test subfolder has espresso/instrumentation tests.

Do you think it is possible to move the Instrumentation tests to a subfolder on the same level as the others? I would prefer to have InstrumentationTests folder alongside Unit/Component.

I have been using android-gradle-template for my project for a while. Since updating to Android Studio 0.8.9 I get this error after opening the AppUnitTests/build.gradle file and then running the test runner:

Error:(19, 0) Gradle: A problem occurred evaluating project ':AppUnitTests'.

The 'android' or 'android-library' plugin is required.

This happens after building the testClasses just before the tests start running. Do you know what could be causing it?

Hi,

I'm trying to make my Robolectric tests work with Jacoco support, but it seems that the plugin is not compatible with Dagger as it can not find some class files with '$$' in the filename. For this reason I got a FileNotFoundException when executing the 'jacocoTestReport' task. Is this related to the 'known issue' on this page: http://tools.android.com/tech-docs/new-build-system or is this something that needs to be fixed in Dagger, Android build tools or the Jacoco plugin?

Thanks.

i use the solution in my project with espresso , task skipped. my build.gralde

apply plugin: 'jacoco'

android {
  buildTypes {
    debug {
      testCoverageEnabled true
    }
  }
  jacoco {
    version "0.7.1.201405082137"
  }


def coverageSourceDirs = [
        'src/main/java',
]

task jacocoTestReport(type: JacocoReport) {
    group = "Reporting"
    description = "Generate Jacoco coverage reports after running tests."
    reports {
        xml.enabled = true
        html.enabled = true
    }
    classDirectories = fileTree(
            dir: './build/intermediates/classes/debug',
            excludes: ['**/R*.class',
                       '**/*$InjectAdapter.class',
                       '**/*$ModuleAdapter.class',
                       '**/*$ViewInjector*.class'
            ])
    sourceDirectories = files(coverageSourceDirs)
    executionData = files("$buildDir/jacoco/testDebug.exec")

    doFirst {
        new File("$buildDir/intermediates/classes/").eachFileRecurse { file ->
            if (file.name.contains('$$')) {
                file.renameTo(file.path.replace('$$', '$'))
            }
        }
    }
}

result:

BUILD SUCCESSFUL

Hey there,

Thanks a lot for sharing. Recently I've upgraded my Android Studio to the latest version (0.8.2) and today I've noticed your project on github. Unfortunately tests don't pass when I run them from script and I am given this error:

A problem occurred evaluating project ':ComponentTestsRobolectric'.

(class: com/novoda/gradle/test/SupportedLanguages, method: super$1$stream signature: ()Ljava/util/stream/Stream;) Illegal use of nonvirtual function call.

Particularily, it complains in this line:

android { projectUnderTest ':AndroidSample' }

Primarily I thought it was connected with java version but it's not.

Is this the Android Studio version issue? Is anyone familiar with this error? If so, how to get it working?

Thanks, Dawid

I'm very thankful that the novoda team created a great plugin to support robolectric. I used this plugin for about one year now. The main advantage was the good support for robolectric + espresso where other plugins had some issues. But I disliked that there was not much support. It's looked like they dropped the support. But since short time they are much more active.

The plugin from JCAndKSolutions has the same support like the novoda plugin, but much better integration with android studio when you install the android studio plugin.

Now i think about to drop the novoda example. Would someone dislike this decision? Please tell me also short why.

1. fresh clone
2. I click "Import Project..." from the "Welcome to Android Studio" window.
3. Select the build.gradle on the root folder
4. I get the following error Error:(17, 0) (class: com/novoda/gradle/test/SupportedLanguages, method: super$1$stream signature: ()Ljava/util/stream/Stream;) Illegal use of nonvirtual function call

I am not sure if I'm missing something, I also tried

1. fresh clone
2. I ran Script/install-custom-gradle-test-plugin.sh from android-gradle-template folder
3. I click "Import Project..." from the "Welcome to Android Studio" window.
4. Select the build.gradle on the root folder
5. I get the same error

I also tried

1. fresh clone
2. I ran install-custom-gradle-test-plugin.sh from android-gradle-template/Script folder
3. I click "Import Project..." from the "Welcome to Android Studio" window.
4. Select the build.gradle on the root folder
5. I get the same error

Hi, Thanks a lot for this template, I'm trying to apply the same structure to my project everything worked fine except in my unit test module i got : Error:(20, 0) (class: com/novoda/gradle/test/SupportedLanguages, method: super$1$stream signature: ()Ljava/util/stream/Stream;) Illegal use of nonvirtual function call

I added : compileOptions { sourceCompatibility JavaVersion.VERSION_1_7 targetCompatibility JavaVersion.VERSION_1_7 } to my app module thinking maybe it's because of java version but that didn't work. should i launch the install script install-custom-gradle-test-plugin.sh and use android-studio-robolectric-support.gradle with a specific java version ?

thanks.

Hi - trying to follow your pattern of sub directories with an existing project. I have tried to replicate what you have almost exactly. Yet when I build I get this error:

• What went wrong: A problem occurred evaluating project ':UnitTestsRobolectric'.

  The 'android' or 'android-library' plugin is required.

It thinks that the main Android application doesn't have the android plugin applied, yet it does! Any idea what I am doing wrong?

The directory structure looks like:

android
   build.gradle
   settings.gradle
   app/
       build.gradle
   UnitTestsRobolectric
       build.gradle

Settings.gradle:

  include ':app', 'UnitTestsRobolectric'

My build.gradle in the top most folder has the same settings as yours, except I use build tools 19.0.1.

app/build.gradle has this at top:

buildscript {
    dependencies {
        classpath 'com.android.tools.build:gradle:0.10.+'
    }
}

apply plugin: 'android'
...

UnitTestsRobolectric/build.gradle has this:

buildscript {
    repositories {
      maven { url 'https://oss.sonatype.org/content/repositories/snapshots/' }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.10.+'
        classpath "com.novoda:gradle-android-test-plugin:0.9.9-SNAPSHOT"
        classpath 'org.kt3k.gradle.plugin:coveralls-gradle-plugin:0.4.0'
    }
}

apply plugin: 'java'

test.reports.html.enabled = false     // just clean up dashboard from not generated reports
test.reports.junitXml.enabled = false // just clean up dashboard from not generated reports

apply plugin: 'android-test'
apply plugin: "jacoco"
apply plugin: 'coveralls'
apply plugin: 'idea'

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

android {
  projectUnderTest ':app'
}

I see this code in the plugin source so I know it must have found the gradle file for the app, but I can't explain why it doesn't see the android plugin applied!

public void projectUnderTest(String projectName) {

    Project projectUnderTest = project.project(projectName)

    def hasAppPlugin = hasAppPlugin(projectUnderTest)
    def hasLibraryPlugin = hasLibraryPlugin(projectUnderTest)

    if (!hasAppPlugin && !hasLibraryPlugin) {
        throw new IllegalStateException("The 'android' or 'android-library' plugin is required.")

Just curious, I see some errors when I run the tests currently. Is that intentional, to show us how errors will look in the reports?

Example: gradlew :UnitTestsRobolectric:testDebug

:UnitTestsRobolectric:testDebug

com.example.activities.DatabaseActivityTest > test_shouldResetAllInputFields FAILED java.lang.UnsupportedClassVersionError at DatabaseActivityTest.java:64

Problem #1: this bug stops me from working:

https://github.com/novoda/gradle-android-test-plugin/issues/10

Problem #2:

In the UnitTestsRobolectric/build.gradle, I've had to change this line:

classpath "com.novoda:gradle-android-test-plugin:0.9.9-SNAPSHOT"

to this other:

classpath "com.novoda:gradle-android-test-plugin:0.9.3-SNAPSHOT"

Otherwise, Gradle cannot download the version.

With Android Studio 1.4 the component tests (appCt) can't resolve the app classes anymore.
