Talk given by Vladimir Gerasimov (Product Management Senior Manager) and Joyce Yeh (Software Engineer) at Salesforce, at STPcon in September 2016

Salesforce delivers three major feature releases a year, made possible with strong collaboration among its team members. In this session we will talk about how Developers and Quality Engineers collaborate in an Agile environment on a daily basis. It all starts with a User Story and ends with satisfied customers. We will walk you through everything in between, from the moment the story is created to the release time when the code is deployed to production. We will use the lifecycle of a User Story to show how different team members are enabled through our Agile process and different tools.

Session Takeaways:


How Salesforce leverages collaboration between Developers and Quality Engineers to deliver 3 major feature releases a year.
How Salesforce maintains the highest quality standards.
What quality and development practices are used in scrum team.
General lifecycle of a User Story from idea to production at Salesforce.

  3. 3. Our Goals Today: • Show you how Developers and Testers collaborate • Show you how Salesforce Technology Organization leverages Agile methodologies to deliver 3 major releases a year • Explain the engineering practices used to maintain the highest quality standards • Provide practical tips on how to start your own agile transformation today
  4. 4. Salesforce Agile Implementation Principles (Lean & Agile) Management Practices (Scrum & Kanban) Technical Practices (XP)
  5. 5. We’ve Built a Scalable Mode 400 + Agile Teams @ Salesforce
  6. 6. Developers at Salesforce are Responsible for: • Test-Driven Development • Unit and Functional Test Automation • Fixing Regression bugs
  7. 7. Quality Engineers at Salesforce are Responsible for: • Test Design and Test Planning • Identifying Test Coverage gaps • Developing Test Frameworks • Writing Test Automation
  8. 8. Agile Teams at Salesforce QE Engineers Product Owner Developers Tech Writer Scrum Master
  9. 9. It’s All About User Story
  10. 10. Collaboration Between Devs and QEs New Triaged In Progress Ready For Review Fixed QE in Progress Closed How Devs and QEs collaborate through User Stories • User Story cannot be closed without QE • Devs and QEs working on the stories together Devs and QEs discussed the work Devs and QEs reviewed the code Code checked in Definition of Done is met
  11. 11. Continuous Planning And Prioritization Vision V2MOM 2 Release Review 1 Release Review Sprint Reviews Stand ups 3-5 years 1 year 2 releases 1 release 2 weeks Daily New Triaged In Progress Ready For Review Fixed QE in Progress Closed
  12. 12. Early communication is the key • Devs and QEs sit together before work on a user story is started • It allows to keep both sides on the same page • Gives Dev first-look test prospective on User Story • Gives QE and idea about what’s coming next New Triaged In Progress Ready For Review Fixed QE in Progress Closed
  13. 13. Freedom to adjust the process Teams decide what work or doesn’t work for them • Team has the freedom to decide best practices • Continuous improvement part of the DNA • Encourages everyone to own the process • Reduces amount of bureaucracy New Triaged In Progress Ready For Review Fixed QE in Progress Closed
  14. 14. Agile Principles to Keep in Mind For quality prospective New Triaged In Progress Ready For Review Fixed QE in Progress Closed • Build quality in. Quality over more features. Trust in #1 priority. • Eliminate waste. Fix test issue, not disable tests.
  15. 15. Dog-fooding Our Own Product Using your product on daily basis • Bug and User story tracking • Internal and external communication • Discovering issues earlier New Triaged In Progress Ready For Review Fixed QE in Progress Closed
  16. 16. Code Reviews • Code reviews help to catch problems before code is checked in • Both Dev and QE engineers participate • Code Review is required for check in • Code Reviewer knows if check in failed New Triaged In Progress Ready For Review Fixed QE in Progress Closed
  17. 17. Pre-Checkin Validation Keeps the Build healthy • Sharing the same code branch for current release work • Important to keep build healthy at all times • Pre-checkin validation ensures the change you are submitting is not breaking the build and major functionality • Takes about one hour New Triaged In Progress Ready For Review Fixed QE in Progress Closed
  18. 18. Test Failures, Flappers and Long Running Tests Lock teams with Test Failures older than 7 days Opening Bugs for non-stable tests Opening Bugs for Long Running Tests Keeping test healthy and stable New Triaged In Progress Ready For Review Fixed QE in Progress Closed
  19. 19. Lock Out Email Team gets locked out if they don't fix their Test Failures New Triaged In Progress Ready For Review Fixed QE in Progress Closed
  20. 20. Test Failure Auto Assign Auto-Assign manages test failures effectively It can link Test Failure to the change list that most likely caused the failure It groups similar test failures under one Bug It eliminates manual work of running reports and opening bugs Even when wrong, it still opens bugs and starts the process of fixing Test Failure Helping teams to address test failures New Triaged In Progress Ready For Review Fixed QE in Progress Closed
  21. 21. How Does Definition of Done help the quality? • Single Definition of Done ensures understanding within & across teams • Increases team accountability for quality and commitment • Reduces Code debt and possible points of failure New Triaged In Progress Ready For Review Fixed QE in Progress Closed
  22. 22. Example of Definition of Done Criteria Features 1 2 3 Code checked in and follows department standards ☑ ☑ No open regressions. Automated tests written and reviewed for all regressions ☑ ☑ No open P1 & P2 bugs ☑ Code Coverage 78 % 80 % 100% of test cases logged and executed in a QA environment, and all P1/P2 cases passing ☑ ☑ All resolved bugs verified and closed ☑ ☑ ☑ UE has reviewed any new features; P1 and P2 UI bugs fixed ☑ ☑ ☑ Usability testing completed when necessary, and feedback incorporated into backlog ☑ ☑ Code and UI reviewed for 508 compliance; UE team notified of any non-compliant features ☑ ☑ New Triaged In Progress Ready For Review Fixed QE in Progress Closed
  23. 23. Frequent Product Demos & Reviews • Demo completed work with team every sprint • Demo and review release plan progress monthly with Executive participation • Provide radical transparency • No surprises come release time New Triaged In Progress Ready For Review Fixed QE in Progress Closed
  24. 24. Frequent Major Releases Feature Freeze Release Freeze Done Done Done Release to Internal Sandbox & Production Instances SB/R0 Release • 2/3 sandbox instances • Production instance where Salesforce has largest orgs R1/R2 Release • 25% of prod instances • All remaining instances • Branch locked • Check-in approval required • Incomplete features disabled • Code line open for next release Monthly Sprint Reviews Release Sprint Staggered Release Scrum Teams and Functional Areas Sign Off Scrum Teams Sign Off Dec Jan Feb Mar MayApr Jun • Continuous integration w/ 600k JUnit and Selenium tests • Performance testing • 110M Apex customer tests • Other production tests • Final performance testing New Triaged In Progress Ready For Review Fixed QE in Progress Closed
  25. 25. Next Steps What you can do today Get Developers to work closer with QEs • Discuss User Story scope and requirements together • Participate in Code Reviews • Have Dev and QE pair on story completion Test Automation • Add Automated Test Coverage to Definition of Done • Create backlog to track remaining Automation work • Involve Developers in writing Automation and helping QEs with Test Frameworks • Test Failures locks when too high • Enforce Test Automation health • Invest in Auto-Assign tools and reports
  26. 26. Thank you!
