title: No tests found when testCoverageEnabled
body: <p>I'm getting this error whenever I try to create a coverage report:</p>
  
  <pre><code>Instrumentation run failed due to 'Process crashed.'
  
  com.android.builder.testing.ConnectedDevice &gt; No tests found.[Pixel 2 - 8.1.0] FAILED 
  No tests found. This usually means that your test classes are not in the form that your test runner expects (e.g. don't inherit from TestCase or lack @Test annotations).
  </code></pre>
  
  <p>I modified a sample repo to reproduce the issue: 
  <a href="https://github.com/suarezjulian/unified-code-coverage-android" rel="nofollow noreferrer">https://github.com/suarezjulian/unified-code-coverage-android</a></p>
  
  <p>just download and execute:</p>
  
  <pre><code>./gradlew jacocoTestReport
  </code></pre>
