z/OSMF is a management facility for z/OS to let customers use it easier. As FVT Lead, I'm responsible for the function test for 3 plug-ins(CP/RM/WLM). I led the work of putting up the currency test environment, the deployment of defect management system and the test work of V1R13 and V2R1. During the project migration process, I received a lot of praise from Germany SME because of strong responsibility. zHYP means IBM zEnterprise integrated platform virtualization. It's a next generation product compared with z/VM. As a test lead of I/O Configuration management component I supported the developer team to write automation test scripts with Python, I'm also responsible for integrating the test suite of sub-component HCD. In the beginning, IOM scripts couldn’t be integrated to CECREGRESS test framework as MCS partition which is the container for IOM was not ready. I got the idea myself to write a script named one-click regression test for MCS partition. The script greatly improved the team efficiency and I also got the article “Using Python to Perform One-Click Regression Test on Linux” published on IBM developerWorks site as lead author.
