In this talk, Qingsong Yao will discussion a set of commonly used engineering principle and practices, namely, Continuous Integration, Continuous Delivery, and various Testing Strategies, which you can use in your daily work. These principles helped many organizations to release their product fast with high quality and were fully integrated into Agile process. He will show demos about how these engineering principle and practices are used in his DAC Import/Export improvement. In additional, he will show how organizations and companies, like Bing team, Protection Services Team, and Google use these principles.

3. • Continuous Integration
• Continuous Delivery
• A Good Testing Strategy
• Testing in Production
• Agile

6. Rapid Componentized Builds
Continuous Integration
Unit Testing Improve service quality and
engineering agility
Operate at Near Zero Bugs
Focused Integration Testing
Effective Exploratory Testing

8. integrate frequently
multiple integrations per
day
automated build and test
as quickly as
possible.

Continuous Integration in .NET

9. Every Commit should build the mainline on
integration machine
Keep the Build fast
Everyone can see what's happening

14. Continuous Delivery
Building, Testing
releasing faster
frequently
Continuous Delivery: Reliable Software
Releases through Build, Test, and
Deployment Automation

15. The process for releasing/deploying software
MUST be repeatable and reliable.
Automate everything!
Done means “released”.
If something difficult or painful, do it more often.

19. Deployment Pipeline models the part of your project’s
value stream that goes from check-in to release, and then
to automate it.

24. Testing Strategy
to fit into the deployment
pipeline

25. know what the customer thinks is truly
important and test for those subjects.

39. Experimentation in Production

right thing we build the thing right

continuous and frequent customer value
delivery
high quality
predictable lower cost.”

44. Test In Production (TiP)
• Continuously and extensively Monitoring and experimental our service in
production
Continuous Deployment
• Frequent deployments of small changes to production environment (starting
with weekly releases)
Continuous Integration
• Minimize the gap between code development and deployment readiness
Pushing Quality Upstream
• Efficient processes to reduce the cost and gaps between product and quality
development
Continuous Improvement
• Constant observation, measurement and feedback on processes ,systems
and cost
