Hello Everyone. I am bit new to Contract testing and recently started exploring it for consumer driven contract testing in Android App. The use case I am trying to solve is to generate pact file while i am running my UI Tests in Android app. My Android app makes multiple API requests to our backend server which i have currently mocked the responses through "Wiremock" framework. The next step i want to do is to record all the interactions made by the app and create a pact file so as i can validate it against my reack backend server. In order to do so i have integrated "Wiremock Pact Generator" developed by Atlassian team : https://bitbucket.org/atlassian/wiremock-pact-generator/src/master/ but i am facing crash while running my UI tests.

Can you raise an issue for that at https://bitbucket.org/atlassian/wiremock-pact-generator

I don't know android, but if you're running a UI test do you have access to the filesystem?
