AndroidManifest.xml not found when using with Android Gradle plugin 1.1.0

[denisk20]

Hello,
I've been successfully using Robolectric with gradle with Android Gradle plugin 1.0.0 without robolectric plugin. However, after updating to 1.1.0 my tests are unable to find the manifest:

WARNING: No manifest file found at ./AndroidManifest.xml. Falling back to the Android OS resources only.

Interesting thing that using both @Config and org.robolectric.Config.properties seem to be ineffective in solving it.
After incorporating your plugin into the project (with 1.1.0 plugin activated) the behavior of my test diverged. In the Android Studio I still get the same errors related to AndroidManifest.xml. When I run tests from console however I get android.content.res.Resources$NotFoundException.
I have 2 build types and 2 flavors. Tests are located under src/test. The manifest is under src/main. I have also tried to add a copy of the manifest just next to my test class, but to no avail.

I know that these issues are only partly related to the robolectric plugin itself, but would still appreciate any insights.

The plugin does not work with Android Studio due to how studio runs tests.

With version 1.0.1 of the plugin, you shouldn't have to use @config, Config.properties or any other configuration to run your tests on the command line.

@erd Thanks for the clarification! Is there a chance that the plugin will work with Studio 1.2 (which is going to be based on IntelliJ 14) ?

This plugin works for me with AS when using custom RobolectricTestRunner and provide the missing system properties.

public class CustomRobolectricTestRunner extends RobolectricTestRunner {

  public CustomRobolectricTestRunner(Class<?> testClass) throws InitializationError {
    super(testClass);
    String buildVariant = BuildConfig.BUILD_TYPE + (BuildConfig.FLAVOR.isEmpty()? "" : "/" + BuildConfig.FLAVOR);
    System.setProperty("android.package", BuildConfig.APPLICATION_ID);
    System.setProperty("android.manifest", "build/intermediates/manifests/full/" + buildVariant + "/AndroidManifest.xml");
    System.setProperty("android.resources", "build/intermediates/res/" + buildVariant);
    System.setProperty("android.assets", "build/intermediates/assets/" + buildVariant);
  }
}

Edit:
You must also use a different working directory at your unit test run configuration. Best is to change the default configuration and use $MODULE_DIR$ https://code.google.com/p/android/issues/detail?id=158015#c5

@nenick Thanks, it works this way, just needed so swap build type and build flavor for build variant. Also checked your examples from https://github.com/nenick/AndroidStudioAndRobolectric, very useful.

@nenick Thanks, I also had to swap the build type and flavor, so my variant ended up looking like this:

import org.junit.runners.model.InitializationError;
import org.robolectric.RobolectricTestRunner;

public class CustomRobolectricTestRunner extends RobolectricTestRunner {

    public CustomRobolectricTestRunner(Class<?> testClass) throws InitializationError {
        super(testClass);
        String buildVariant = (BuildConfig.FLAVOR.isEmpty() ? "" : BuildConfig.FLAVOR + "/") + BuildConfig.BUILD_TYPE;
        System.setProperty("android.package", BuildConfig.APPLICATION_ID);
        System.setProperty("android.manifest", "build/intermediates/manifests/full/" + buildVariant + "/AndroidManifest.xml");
        System.setProperty("android.resources", "build/intermediates/res/" + buildVariant);
        System.setProperty("android.assets", "build/intermediates/assets/" + buildVariant);
    }
}

We have build flavors with different applicationIds (such like "com.example" and "com.example.development").
We also had to change from BuildConfig.APPLICATION_ID to default application id.

https://github.com/robolectric/robolectric-gradle-plugin/blob/master/src/main/groovy/org/robolectric/gradle/RobolectricPlugin.groovy#L24

public class CustomRobolectricTestRunner extends RobolectricTestRunner {
    public CustomRoblectricTestRunner(Class<?> testClass) throws InitializationError {
        super(testClass);
        String buildVariant = (BuildConfig.FLAVOR.isEmpty() ? "" : BuildConfig.FLAVOR + "/") + BuildConfig.BUILD_TYPE;
        System.setProperty("android.package", BuildConfig.DEFAULT_APPLICATION_ID);
        System.setProperty("android.manifest", "build/intermediates/manifests/full/" + buildVariant + "/AndroidManifest.xml");
        System.setProperty("android.resources", "build/intermediates/res/" + buildVariant);
        System.setProperty("android.assets", "build/intermediates/assets/" + buildVariant);
    }
}

build.gradle:

def defaultApplicationId = "com.example"

android {
        applicationId defaultApplicationId
        buildConfigField "String", "DEFAULT_APPLICATION_ID", "\"${defaultApplicationId}\"" // for robolectric
        ...
}

(EDITED: at least with android gradle plugin 1.5.0, "build/intermediates/res/" must be "build/intermediates/res/merged/")

Above test runner works well on both Android Studio unit test and Gradle test even without robolectric-gradle-plugin. (Also setting $MODULE_DIR$ #142 (comment))

[DanielGrech]

For me the problem was because my class package (com.my.class.package) was different from my applicationId (com.my.app)

I fixed by adding packageName = "com.my.class.package" to my @Config

[xtien]

I had to add my build variant "app" to the string: "app/build/.... "

[davidgoli]

The current correct solution is to use the RobolectricGradleTestRunner like so:

@RunWith(RobolectricGradleTestRunner.class)
@Config(constants=BuildConfig.class, sdk=21) // robolectric currently only supports up to API 21, sadly
public class CustomTest {
...

I struggled with this for a while but eventually came up with a RobolectricTestRunner implementation that works for our setup:

• We have two flavours, release for production and debug for internal testing. The latter is what we test against.
• The debug flavour has an applicationIdSuffix of .debug

public class RobolectricTestRunnerWithResources extends RobolectricTestRunner {

    @Override
    protected Config buildGlobalConfig() {
        return Config.Builder.defaults()
                .setPackageName("co.beeline")
                .setManifest("build/intermediates/manifests/full/debug/AndroidManifest.xml")
                .setResourceDir("../../../res/merged/debug") // relative to manifest
                .setAssetDir("../../../assets/debug") // relative to manifest
                .build();
    }

    public RobolectricTestRunnerWithResources(Class<?> testClass) throws InitializationError {
        super(testClass);
    }
}

@chetbox How did you manage to set the manifest correctly? For me it just appends the given string to the default prefix so that the resulting path is

build/intermediates/bundles/debug/build/intermediates/manifests/full/debug/AndroidManifest.xml

[chetbox]

This works for us. It might be that a different version of the Android SDK or Robolectric behave differently.
