Jenkins Plugin 1.3.0 now supports Jenkins Pipeline with qTest Manager for advanced continuous integration scenarios. You can now generate a pipeline script from the qTest Jenkins Plugin to submit test results to qTest Manager. The script, once generated, can be used as a step in your entire pipeline scripts.
Previously, if you were using Jenkins Pipeline you would need to use the QASymphony API directly to upload your test results.
