Android unit test - subclass InstrumentationTestRunner not found

I had another problem using the InstrumentationTestRunner subclass.

Here's the code for the subclass:

package com.jlptquiz.app.tests; /** * */ import junit.framework.TestSuite; import android.test.InstrumentationTestRunner; import android.test.InstrumentationTestSuite; public class MyInstrumentationTestRunner extends InstrumentationTestRunner { public TestSuite getAllTests(){ InstrumentationTestSuite suite = new InstrumentationTestSuite(this); suite.addTestSuite(UtilsTestCase.class); return suite; } public ClassLoader getLoader() { return MyInstrumentationTestRunner.class.getClassLoader(); } }

Here's the unit test:

 package com.jlptquiz.app.tests; import com.jlptquiz.app.Utils; import junit.framework.Assert; import android.app.Activity; import android.content.Context; import android.net.wifi.WifiManager; import android.test.ActivityInstrumentationTestCase2; import android.util.Log; public class UtilsTestCase extends ActivityInstrumentationTestCase2 { private Context mContext; private Utils utils; public static String TAG = "GetResourceStringTestCase"; public UtilsTestCase() { super("com.jlptquiz.app", Utils.class); } public void setup() { try { super.setUp(); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } mContext = this.getInstrumentation().getContext(); } public void testRandomNumberEqaulsOne() { utils = (Utils) this.getActivity(); int randNum = Utils.genRandomNumber(1, 1); Integer actual = Integer.valueOf(randNum); Integer expected = Integer.valueOf(1); Assert.assertSame(expected, actual); } }

Here's the manifest:

 <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.jlptquiz.app" android:versionCode="1" android:versionName="1.0"> <application android:name="AppState" android:debuggable="true" android:clearTaskOnLaunch="true" android:icon="@drawable/ic_icon" android:label="@string/app_name"> <activity android:name="JlptQuizStartActivity" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name="QuestionActivity"></activity> <activity android:name="AnswerActivity"></activity> <activity android:name="SettingsActivity"></activity> <uses-library android:name="android.test.runner" /> </application> <instrumentation android:label="AllTests" android:name="com.jlpt.quiz.app.tests.MyInstrumentationTestRunner" android:targetPackage="com.jlptquiz.app"/> <uses-sdk android:minSdkVersion="5" /> </manifest>

And the launch configuration, android junit testing configuration, points MyInstrumentationTestRunner as an implementation of TestRunner.

But I came up with a class exception not found in MyInstrumentationTestRunner, according to logcat:

Any idea where I am going to go here?

change

 **package="com.jlptquiz.app.tests"** **android:targetPackage="com.jlptquiz.app.tests"/>**

Run

 $ adb -s <serialno> shell pm list instrumentation

to make sure your equipment is defined exactly as you expect.

Then make sure your test project manifest includes

  <uses-library android:name="android.test.runner" />

Finally, run the tests.

In the end, I returned to the Google docs and did what they recommended, which creates a separate project for testing. This processes all manifest.xml files for you.
