title: Test events were not received - Android Studio
body: <p>I have no idea how to test and I was following a tutorial.I am trying to run: </p>
  
  <pre><code>package name.company.sunshine.app.data;
  
  import android.test.AndroidTestCase;
  
  public class TestPractice extends AndroidTestCase {
       /*
         This gets run before every test.
       */
      @Override
      protected void setUp() throws Exception {
          super.setUp();
      }
  
      public void testThatDemonstratesAssertions() throws Throwable {
          int a = 5;
          int b = 3;
          int c = 5;
          int d = 10;
  
          assertEquals("X should be equal", a, c);
          assertTrue("Y should be true", d &gt; a);
          assertFalse("Z should be false", a == b);
  
          if (b &gt; d) {
              fail("XX should never happen");
          }
      }
  
      @Override
      protected void tearDown() throws Exception {
          super.tearDown();
      }
  }
  </code></pre>
  
  <p>but I get somewhere in the bottom left corner, in the console <code>Test events were not received</code>. What am I doing wrong ? Should I run something else ? </p>
