Semi-automation of applications that use third-party API: getting rid of redundant dependencies

Some applications that use third-party API often have complicated branched structure. Manual testing of them means a great amount of routine work which takes much time. We can divide this task into two subtasks for simplification. One of them is testing the application in isolation from API using mocks. The other is testing API itse. We tried this on one of such products –  Amigo browser which is developed by our company.    

I’ll tell you how to make manual tester’s life easier during regression testing by using simple popular tools and without coding.
