Docker based Integration Tests

[AlexKorovyansky]

Implement several docker containers: one for Android app itself, second for emulation of remote manifest storage and static files providers, third for GCM, and so on.

Test environment should has zero dependency from external world for all features under test.

Use Espresso and/or UiAutomation for automation of user actions.

At the end of this video @shykes briefly describes idea of properly usage Docker for faking remote services (on example of Twitter API).

Also the talk is very useful for understanding of Docker basics.

Spent about 12 hours by learning Docker and playing with it. As I can see it's brilliant and effective solution for our case!

I already made image for run Fake Test Server, that's serving static files around manifest.json.

Steps to do:

• Make image for running android app inside container
• Configure connection of server and android app containers during test session
• Write some tests
• Run tests and check that docker environment is working correclty
• Upload images to Docker Hub
