Test strategies and flow and sharing of strategies

  • Test pipelines and integration strategies across teams
  • Architecture
  • It’s so important to assume you will miss something .. so MTTR is critical

War stories

  • Defeat: why can’t anyone deploy anything
  • Victory: 3 months to change a web page —> changes in 1 day
    • Text link to 404 for the purpose of recording clicks of interest for house viewing
  • PJ: Company daily release process but often would break and often take 3 people most of the day to get it out
    • Eventually, every time someone made a change of the code it would be deployed to prod and monitored
      • End to end test bankruptcy
    • Success
    • Monolithic system (with seams but tight coupling) was broken down into component based independently deployable systems
    • Be prepared, this process will take 3 years (or more)
    • How do you sell this idea?
      • The key to our success is shortening our feedback cycles
      • From Tony later: show other companies that are already past 3y to show what’s possible (and build trust)
  • Tim: traditionally siloed functional org
    • Idea to cash was ~ 200d
    • 91% wait time
    • First response was to be mad at the person pointing at the problem
    • Improvement is slow, but it is improving
    • It was important to just get people talking about it even if they got upset initially
    • Value stream map made it all possible
  • Christophe - Success: Operations team and developer teams
    • Devs write run-books over a couple months, then throw it to the operators
    • Big bang release every couple of months
    • Build a more intimate relationship between Dev and Ops
      • Moved to central Jenkins instance from individual snowflakes
      • This integrated the dev workflow with the ops workflow (common environment)
    • Decoupled infra track from application track for deployments
    • Over a 6 month period — still monthly releases but far less stressful on everyone involved
    • Enjoyable pizza
  • Frederick: Goal: faster release cycle — get to weekly
    • Current was monthly with bi-weekly patch releases
    • Visualized value stream maps with both
    • Took similarities and combined to 1 flow like the patch flow — currently at every 2w
    • Giant monolith
    • There were a lot of fears and resistance but enough trust was built to give it a try
    • Now trying to work towards TBD
  • Small web team gets security scan result
    • Pen testers test quarterly — first report was very ugly
    • Introduced PR process, but devs weren’t able to spot security vulnerabilities
    • Secure Code Warrior gamefies this .. points for vulnerabilities found
    • Got some training (e.g. OWASP) and testers were more involved
    • Making progress
    • “Why should I train you (freelancer), what if you leave"
      • “What if you don’t train us and we stay” (response)
  • Jonathon - Failure:
    • Cultural, hierarchical issues with a Dev silo, QA silo (which moved closer) and DevOps (eww) silo which was moved even further away
    • Improvements were made in delivering more often, but then there was some realization/questioning of this and so deliveries are now getting slowed/spaced out
