 /**
  * Tests using Proguard/R8 to shrink and obfuscate code in a project with features.
  *
  * Project roughly structured as follows (see implementation below for exact structure) :
  *
  * <pre>
  *                  --->  library2  ------>
  *   otherFeature1  --->  library3           library1
  *                  --->  baseModule  ---->
  *   otherFeature2
  *
  * More explicitly,
  *    instantApp  depends on  otherFeature1, otherFeature2, baseModule  (not pictured)
  *           app  depends on  otherFeature1, otherFeature2, baseModule  (not pictured)
  * otherFeature1  depends on  library2, library3, baseModule
  * otherFeature2  depends on  baseModule
  *    baseModule  depends on  library1
  *      library2  depends on  library1
  * </pre>
  *
  * This test is taken from [MinifyFeaturesTest] and modified to enable data binding.
