title: AndroidJUnit4 test not found
body: <p>I annotated my class like here</p>
  
  <pre><code>@RunWith(AndroidJUnit4.class)
  public class WorkdayProviderTest
  </code></pre>
  
  <p>Futhermore, annotated also my test method like this</p>
  
  <pre><code>@Test
  public void insert_dataInsertsCorrectly()
  </code></pre>
  
  <p>Finally, configured my build.gradle defaultConfig and dependencies like this</p>
  
  <pre><code>defaultConfig {
      applicationId 'com.jueggs.workinghours'
      minSdkVersion 16
      targetSdkVersion 23
      versionCode 1
      versionName "1.0"
  
      testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
  }
  
  androidTestCompile "junit:junit:4.12"
  androidTestCompile "com.android.support:support-annotations:23.3.0"
  androidTestCompile "com.android.support.test:runner:0.4.1"
  androidTestCompile "com.android.support.test:rules:0.4.1"
  androidTestCompile "com.android.support.test.espresso:espresso-core:2.2.1"
  androidTestCompile "com.android.support.test.espresso:espresso-contrib:2.2.1"
  androidTestCompile "org.hamcrest:hamcrest-library:1.3"
  </code></pre>
  
  <p>and configured the test run like this</p>
  
  <p><a href="https://i.stack.imgur.com/6NAvN.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/6NAvN.png" alt="enter image description here"></a></p>
  
  <p>and it´s telling me</p>
  
  <pre><code>No tests were found
  
  Test running failed: Instrumentation run failed due to 'java.lang.ClassNotFoundException'
