How to run integration tests

I have solved #932. It passes locally, on Travis and AppVeyor, but fails on rultor with random errors. See #1170

README for this project explains how to run separate integration test, but I want to run all tests when build project (test task).

I suppose that we need add properties as follows:

failsafe.github.key
failsafe.github.key.second
failsafe.github.repo
failsafe.github.organization

I have tried to add the failsafe.github.key property, but don't know how to add others. I don't have two github accounts and not sure if there are more required properties as well as what to set for these properties.

Can someone help?
