* Test to verify view inflation does not happen during swipe up.
|

* To verify view inflation, we setup a stub 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
