Android Studio 3.0 Beta2
classpath 'com.android.tools.build:gradle:3.0.0-beta3'
testCompile 'org.robolectric:robolectric:3.4.2'
Test class that I am using that fails to run:
@Config(constants = BuildConfig.class, sdk = Build.VERSION_CODES.LOLLIPOP)
@RunWith(RobolectricTestRunner.class)
public class RecipeAdapterTest {
private MainActivity activity;
@Before
public void setup() {
activity = Robolectric.setupActivity(MainActivity.class);
/* Also tried this same Error
activity = Robolectric.buildActivity(MainActivity)
.create()
.resume()
.get();
*/
}
@Test
public void testActivityShouldNotBeNull() {
assertThat(activity, is(notNullValue()));
}
}
This is the stack trace of the error:
android.content.res.Resources$NotFoundException: String resource ID #0x7f0c0020

In the Edit Configurations
I have set the Working Directory
to $MODULE_DIR$
Many thanks for any suggestion.
As mentioned by an engineer from Google team (most possibly Xavier Ducrohet), Robolectric has issues with AAPT2:
Robolectric is not compatible with aapt2.
Two options here.
First option - follow Robolectric guidelines for Android Studio 3.0+
Add the following to your build.gradle:
android {
testOptions {
unitTests {
includeAndroidResources = true
}
}
}
Annotate your test with the Robolectric test runner:
@RunWith(RobolectricTestRunner.class)
public class SandwichTest {
}
Second option: disable AAPT2 adding following line into gradle.properties
file:
android.enableAapt2=false
