MockService holds a mutable array of Interactions. When tests are run, mockService gets re-instantiated for each of the tests and nullifies the array. When sending it to PactSwiftMockServer to verify and write the Pact contract, any previously run tests are lost.

A way to keep a reference to one instance of MockService is to wrap it in a singleton.
See README.md and pact-swift-examples.
