Description
This test verifies that the asynchronicity of the subscriber
library
Pre-conditions

Each provider offers one property.
1 provider is delayed (3s).
Steps
Subscribe to both properties
Verify that return values are correct
Measure the time elapsed between the reception of the 2 values.
Post-conditions
