Android IllegalStateException No instrumentation registered! Must run under a registering instrumentation
I am struggling to make this functional test with Espresso work on Android. My App is a Multdex app so I am following the instructions written at this link as follows : (https://developer.android.com/tools/building/multidex.html).
I have already configured my build.gradle like this :
apply plugin: 'com.android.application'
apply plugin: 'android-apt'
def AAVersion = '3.3.2'
buildscript {
repositories {
mavenCentral()
}

}
}
I configured the Run profile from the Android Studio setting the testInstrumentationRunner classe to com.android.test.runner.MultiDexTestRunner.
When I execute the command "adb shell pm list instrumentation" I have this output:
instrumentation:br.com.doe.test/com.android.test.runner.MultiDexTestRunner (target=br.com.doe)
instrumentation:br.com.foo.test/com.android.test.runner.MultiDexTestRunner (target=br.com.foo)
instrumentation:br.com.foo/com.android.test.runner.MultiDexTestRunner (target=br.com.foo)
But still I receive this output when I try to execute my tests:
Testing started at 17:23 ...

pkg: /data/local/tmp/br.com.foo

java.lang.IllegalStateException: No instrumentation registered! Must run under a registering instrumentation.

at android.app.Instrumentation$InstrumentationThread.run(Instrumentation.java:1701)
Finish
And this is the unique test that I am trying to run:
package br.com.doe.inicio;
import android.support.test.InstrumentationRegistry;
import android.support.test.espresso.Espresso;
import android.support.test.espresso.action.ViewActions;
import android.support.test.espresso.matcher.ViewMatchers;
import android.support.test.runner.AndroidJUnit4;
import android.test.ActivityInstrumentationTestCase2;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import br.com.foo.R;
@RunWith(AndroidJUnit4.class)
public class MapaEnderecoTest extends ActivityInstrumentationTestCase2<MapaEndereco>
{
private MapaEndereco mActivity;
public MapaEnderecoTest()
{
super(MapaEndereco.class);
}
@Override
@Before
protected void setUp() throws Exception
{
super.setUp();
injectInstrumentation(InstrumentationRegistry.getInstrumentation());
mActivity = getActivity();
}
@Test
public void testeAbertura()
{
Espresso.onView(ViewMatchers.withId(R.id.map)).perform(ViewActions.click());
}
}
The error occurs right after the super.setUp() call, on the setUp method.
I have the instrumentation registered into the AndroidManifest file:
<instrumentation
android:label="Multdex"
android:name="com.android.test.runner.MultiDexTestRunner"
android:targetPackage="br.com.foo"
android:functionalTest="true"/>
And the problem I am facing is not the same as described here NullPointer Exception when using Espresso
Answer
The problem is with these gradle lines:
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
testInstrumentationRunner "com.android.test.runner.MultiDexTestRunner"
You need a MultiDexTestRunner, but this class is derived from InstrumentationTestRunner. Your code needs a test runner that is derived from AndroidJUnitRunner
A solution is to create a custom TestRunner that extends AndroidJUnitRunner and implements the MultiDex code:
import android.os.Bundle;
import android.support.multidex.MultiDex;
import android.support.test.runner.AndroidJUnitRunner;
public class TestRunner extends AndroidJUnitRunner
{
@Override
public void onCreate(Bundle arguments)
{
MultiDex.install(getTargetContext());
super.onCreate(arguments);
}
}
You only need to add a single Gradle line that references your custom testInstrumentationRunner. This will ensure that the build system generates the AndroidManifest.xml properties that are needed to run the tests with this runner.
