Hi,

I checked out the source code and run this command ./gradlew clean test. It's stuck at

:app:processDebugManifest
:app:processDebugResources
:app:generateDebugSources
:app:compileDebugJava
:app:preCompileDebugUnitTestJava
:app:compileDebugUnitTestJava
:app:compileDebugUnitTestSources
:app:mockableAndroidJar
:app:assembleDebugUnitTest
> Building 54% > :app:testDebug

Do you have any idea how can I resolve this issue?

Thanks!
Henry

Hi ,
trying to run the RobolectricCoreTest (from multimodule example) fails with RuntimeException "\res\debug\values is not a directory".
Any ideas?

This is not an issue. But I would love to buy you a coffee! I've been banging my head for the past 4 weeks on setting up test suites for library based projects without Activity's. I just got my first passing test case thanks to your repository! :D (Not joking about the coffee, its the least I could do!)

When updating to the latest RC for Robolectric 3.0, the tests no longer work, but lead to the following error:

java.lang.RuntimeException: /Users/mtotschnig/entwicklung/AndroidStudioAndRobolectric/app/build/intermediates/bundles/debug/res/values is not a directory

The issue with missing src/test/resources is tracked at https://code.google.com/p/android/issues/detail?id=136013

There is a known workaround https://code.google.com/p/android/issues/detail?id=136013#c10
Another approach can be found at evant/android-studio-unit-test-plugin#4

Looks like same issue #12
This error can be removed by running an unit test from the main module first.

I don't know if this issue happens only at windows, but as I just run the the project as it is, and got the issue plus, no other related issue was filed, I guess it could be.

I just ran RobolectricTest (right click) and got:

 java.lang.RuntimeException: java.lang.NoSuchMethodException: android.os.Looper.<init>(boolean)
    at org.robolectric.util.ReflectionHelpers.callConstructor(ReflectionHelpers.java:233)

    at org.robolectric.shadows.ShadowLooper.access$000(ShadowLooper.java:25)
    at org.robolectric.shadows.ShadowLooper$1.create(ShadowLooper.java:37) ... 

I came from stackoverflow.com question.(http://stackoverflow.com/questions/29714750/android-studio-1-1-0-cannot-setup-robolectric).
Thanks for your answer but I have cloned your project and tested your code, but Android Studio cannot recognise @config and @RobolectricTestRunner annotations when I added @config(emulateSdk = 18)
@RunWith(value = RobolectricTestRunner.class) in the ApplicationTest class.
Please let me know how I fix the issue.

import android.app.Application;
import android.test.ApplicationTestCase;

import org.junit.runner.RunWith;

/**
 * <a href="http://d.android.com/tools/testing/testing_android.html">Testing Fundamentals</a>
 */
@Config(emulateSdk = 18)
@RunWith(value = RobolectricTestRunner.class)
public class ApplicationTest extends ApplicationTestCase<Application> {
    public ApplicationTest() {
        super(Application.class);
    }
}

The issue is tracked here https://code.google.com/p/android/issues/detail?id=144573

A workaround is to add following line to the module build.gradle
android.sourceSets.test.java.srcDirs += "build/generated/source/r/debug"

We have downloaded AndroidStudioAndRobolectric-library-with-aar.zip and try to run testcase for core package and we were getting issue for same
android/support/v7/appcompat/R$styleable
java.lang.NoClassDefFoundError: android/support/v7/appcompat/R$styleable

Is it a open issue ?

Use of android-unit-test plugin allows for configuring the number of forks to use during test execution, as does having a vanilla java module within the project to host the unit tests. This is typically achieved by configuring a 'maxParallelForks' value in the build scripts.

Such configuration has allowed my test suite to complete in ~3.5 mins. Without it, it takes over 10 mins.

A way to configure an equivalent to 'maxParallelForks' using this setup would definitely be appreciated.

Firstly, really appreciate this great starter project. Was it not intended for open source use? I did not see any copyright information.

This works not out of the box but workaround can be found at
https://code.google.com/p/android/issues/detail?id=144664

Running Robolectric tests fail with a android.content.res.Resources$NotFoundException when in build.gradle the applicationId is changed.

The exception happens when applicationId is set in defaultConfig or a build flavor to a value different than the one in the AndroidManifest. Same thing happens when applicationIdSuffix is used.

I added a very simple activity with a very simple layout and i get following exception when running the test.

java.lang.StringIndexOutOfBoundsException: String index out of range: -9

at android.view.View.__constructor__(View.java:3677)
at android.view.View.<init>(View.java)

The layout is very simple (empty).

 <?xml version="1.0" encoding="utf-8"?>
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
          android:orientation="vertical"
          android:layout_width="match_parent"
          android:layout_height="match_parent">

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/myId"/>
</LinearLayout>

The Test is only creating the activity.

@RunWith(CustomTestRunner.class)
@Config(constants = BuildConfig.class)
public class TestSimpleActivity
{
 @Test
public void test()
{
    SimpleActivity activity =  Robolectric.buildActivity(SimpleActivity.class).create().start().resume().visible().get();

    Assert.assertEquals(true, "test".equals("fail"));
}
}

Any ideas or suggestions?

Same root cause like #12

This error can be removed by running an unit test from the main module first.

When I have the issue java.lang.NoClassDefFoundError: android/support/v4/view/OnApplyWindowInsetsListener then it helped me to do a gradle refresh and close the current project at Android Studio and reopen the project at the project selection window.

When you try to run unit tests from a library module then you must compile the main sources first. gradle lib:assembleDebug

Issue is tracked at https://code.google.com/p/android/issues/detail?id=158251

This issue is tracked at https://code.google.com/p/android/issues/detail?id=52962

Solution is to make the main project depend on different build types ...
... setting this in the dependency project

android {
    publishNonDefault true
}

and this in the project that uses it

dependencies {
    releaseCompile project(path: ':theotherproject', configuration: 'release')
    debugCompile project(path: ':theotherproject', configuration: 'debug')
}

Fresh checkout of this project and I can't get it to work. Gradle experimental Unit Test support is enabled.

Thanks for this project!

When I try to run your library example and want to execute the RobolectricCoreTest I get this exception:

Is there any way that I can fix that one? Basically every Unit Test class works except for RobolectricCoreTest

Adding android.sourceSets.test.java.srcDirs += "build/generated/source/r/debug" worked for the R. issue.

Hi,
first thanks a lot for the example project..
I am trying to setup my first test in a android library following your example but I am getting following error when launching the test.

InflateException... line #-1 (sorry, not yet implemented): Error inflating class

Any ideas what i am doing wrong ?
Thanks!
