title: Running Android Test - The APK file "...-androidTest.apk" does not exist on disk
body: <p>I'm attempting to run a specific android test (JUnit &amp; Espresso), but get the following error:
  <a href="https://i.stack.imgur.com/BeaNA.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/BeaNA.png" alt="Error"></a></p>
  
  <p>I'm executing the test as so (debug):
  <a href="https://i.stack.imgur.com/xiyQ5.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/xiyQ5.png" alt="Running Test"></a></p>
  
  <p>The app is successfully installed and usable after the process.</p>
  
  <p>The directory <code>/Users/user/Projects/kiwix-android/app/build/outputs/apk/androidTest/</code> does not exist and is not created, let alone the <code>app-kiwix-debug-androidTest.apk</code> file itself.</p>
  
  <p>My aim is to be able to debug (breakpoints etc.) individual tests on a real device.
  All suggestions welcome!</p>
