    <p>I'm having another problem with using a subclass of InstrumentationTestRunner.</p> <p>Here's the code for the subclass: </p> <pre><code>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(); } } </code></pre> <p>Here's the unit test:</p> <pre><code>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); } } </code></pre> <p>Here's the manifest:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.jlptquiz.app" android:versionCode="1" android:versionName="1.0"&gt; &lt;application android:name="AppState" android:debuggable="true" android:clearTaskOnLaunch="true" android:icon="@drawable/ic_icon" android:label="@string/app_name"&gt; &lt;activity android:name="JlptQuizStartActivity" android:label="@string/app_name"&gt; &lt;intent-filter&gt; &lt;action android:name="android.intent.action.MAIN" /&gt; &lt;category android:name="android.intent.category.LAUNCHER" /&gt; &lt;/intent-filter&gt; &lt;/activity&gt; &lt;activity android:name="QuestionActivity"&gt;&lt;/activity&gt; &lt;activity android:name="AnswerActivity"&gt;&lt;/activity&gt; &lt;activity android:name="SettingsActivity"&gt;&lt;/activity&gt; &lt;uses-library android:name="android.test.runner" /&gt; &lt;/application&gt; &lt;instrumentation android:label="AllTests" android:name="com.jlpt.quiz.app.tests.MyInstrumentationTestRunner" android:targetPackage="com.jlptquiz.app"/&gt; &lt;uses-sdk android:minSdkVersion="5" /&gt; &lt;/manifest&gt; </code></pre> <p>And the run configuration, an android junit test configuration, specifies MyInstrumentationTestRunner as the ImplementationTestRunner. </p> <p>But, I'm coming up with a class not found exception on the MyInstrumentationTestRunner, as per logcat:</p> <pre><code>/AndroidRuntime( 835): &gt;&gt;&gt;&gt;&gt;&gt;

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
