Hello,
i would like to help writing specs for this issue but i have several question

1. In Core::HttpRequest there is get and post class method, where i should test the post method? Since creation of new task require authentication
2. For http instance method why the http.verify_mode = OpenSSL::SSL::VERIFY_NONE ? since this option is used only for debugging not for production.

Update:
I have figure it out that I can use VCR gem

Thank you
