+ * Test to verify view inflation does not happen during swipe up.
+ * To verify view inflation, we setup a dummy ViewConfiguration and check if any call to that class
+ * does from a View.init method or not.
+ *
+ * Alternative approaches considered:
+ *    Overriding LayoutInflater: This does not cover views initialized
+ *        directly (ex: new LinearLayout)
+ *    Using ExtendedMockito: Mocking static methods from platform classes (loaded in zygote) makes
+ *        the main thread extremely slow and untestable
