Implement end-to-end tests execution #69
Description
Is your feature request related to a problem? Please describe.
This feature request is no related to a problem, directly. But it's related to avoid problems.
In order to establish a safety net we should have a way to execute end to end test for the different user stories of this project.
These end to end tests will be also part as the "low-level" documentation of the project
Describe the solution you'd like
Since we have external dependencies with the google api server, we should add an container that will behave as the google api server but being a mock that allow us to prepare tests fixtures as we need.
We'll need to:
- Add a mock server
- Write tooling to prepare end to end fixtures
- Define user stories of this tool
- Write end to end tests
Additional context
Google APIs behaviour will be documented here also, inspecting how requests and responses look like.
