Description
This test verifies that valueChanged signals are emitted

property.
Pre-conditions
Steps
1. starts two providers (A and B) providing the same property
the property is respectively initialised to V1 and V2
2. starts a client
3. provider A sets the property to V2, a signal is emitted
since V2 is different than previous value V1
4. provider B sets the property to V1, a signal is emitted
since V1 is different than previous value V2
5. provider A sets the property to V1, a signal is emitted
since V1 is different than previous value V2
6. provider B sets the property to V2, a signal is emitted
