QB has extensive integrations for a lot of Development tools and utilities like repositories, unit test frameworks, artifactory etc.
We utilize HP ALM tool which is one of the leaders when it comes to QA automation and integrations. They have a new product called HP Octane which is more of a new age product line with rest api and integrations with external tools like Jenkins, Teamcity etc.
Their current implementation of Jenkins includes HP Octane having full ability to kick off any of its tasks using Jenkins. We spoke and they are also looking into how pipe line driven tools like QB, electric cloud can make use of their new rest api to now kick off QA regressions as well directly from CI and have CI reports for the same.
