Automated functional testing of mobile applications. Is it possible to?

Question

Automation

Good afternoon.
A question of this nature is what tool or set of tools can be used to organize automated functional testing of mobile applications (Android + iOS).
This means not only automating the UI flow of the application, but also checking its back-end part (whether any calculations are being made correctly, whether the data is displayed correctly ....).
For example, a user visits a certain page, sees the number 10 there - the test takes this number and through the API it is correct, and so on.
ATP in advance.

Answer 1

You somewhat misunderstand the structure of the testing process. For the interface, there are UI tests, in the case of Android, this is Espresso. For everything else, instrumental and unit tests.
If you want to check values ​​while testing an interface, it definitely indicates a problem with the architecture, namely that the interface is too tightly coupled to everything else.
