code. If there is a backlog in exploratory testing, people who normally do development will help test. Software engineers will oversee their code in production and help make changes to the infrastructure importance. Tests and infrastructure are now both represented in code; with SDN, soon even the network will be. Infrastructure can now be tested, like code; it can be placed in version control.  Technology

★配置webhook自动化触发功能 首先配置允许向本地网络（私有网段地址）发送webhook通知，如果不配置则 会报错： 管理员用户登录，点击设置： 勾选“Allow requests to the local network from webhooks and integra�ons” 点击“保存” 然后普通用户就可在自己的项目里配置“WebHook”功能了 Se�ngs→Webhooks→Add new webhook

work were significantly behind schedule. Surprising discovery: only 50% of the source code in Dev/Test environments matched Prod. They fixed forward, but changes not put back into version control. Focused automated environment creation – time reduced from 8 weeks to 1 day b. ENABLE ON-DEMAND CREATION OF DEV, TEST, AND PRODUCTION ENVRIONMENTS i. Major contributing cause of issues stems from releases representing Reliable Automated Testing a. Undesired outcomes result from finding and fixes errors in a separate test phase. b. Delayed feedback fades the cause & effect link of the error; now requires firefighting

PRACTICE i. Ensure automated tests demonstrate use and behavior of libraries and components ii. Test suite becomes the living documentation of the system specification and represent working examples Testing on the Toilet periodical 1. Started Test Certified Levels for teams and products to measure themselves against 2. Provide Test Certified Mentors and Test Mercenaries to kick start testing efforts code review 3. Instrument the repository to detect suspicious code (API calls from certain types of test code) 4. Ensure every CI process is in an isolated container 5. Make the version control credentials

technical learning.  How we need to improve  Sharing ideas, code, Community of Practice, etc.  Test Driven Infrastructure  Blue – green deployments  Combining DevOps Scrum – planning, standups Large-Scale Scrum, Craig Larman  Continuous Delivery: Reliable Software Releases through Build, Test, and Deployment Automation, Jez Humble and David Farley  The Phoenix Project: A Novel About IT

risks to delivery? What assumptions are contained in the plans? How will the team move quickly to test those assumptions and gain information to manage the risks? I want to understand their plan for learning of discovery and innovation, during which they begin with a goal in mind and empirically find and test hypotheses. A Better Way – Desired Outcomes: We must replace the notion of requirement with that
