Setup

[uv48uson]

Im currently trying to get some very simple python pact examples running. This project seemed to be the most simple one. So i tried it. Unfortunately im not even getting this one to run properly. And im getting very confused by the requirments. what i did was:

downloaded the project
followed the description and did the install & execution
Im getting the folling error

invoke test_consumer

Now i have a couple of questions:

Do i have to install and run the pact mock service independently or should this be done automatically?
Why does the example fail?
Do i need any additional packages?
Is there a more detailed guideline available? Or is this one even up-to-date?
Is pact python mature enough? Just for simple and demostrative issues?
