Tools iv. 2014 State of DevOps Report environment interactions 3. Ch. 10 Enable Fast and Reliable Automated Testing a. Undesired outcomes result from finding and fixes errors in a separate test phase. b. Delayed feedback fades the cause & effect tests. Spread Testing Grouplet team approach. Google – single, share repository of billions of files. 50% of code is changed each month. 40K code commits/day, 120K automated test suites, 75M tests cases/day

sizes. 2. Large batch sizes result in skyrocketing levels of WIP and high levels of variability in flow that cascade through the entire manufacturing plant. The result is long lead times and poor quality that causes delay for the customer, such as activities that can be bypassed without affecting the result. The following categories of waste and hardship come from Implementing Lean Software Development

which developers can produce something, get feedback, and then adjust what they have produced. As a result, the code can be developed in a user-centric way and match the enterprise’s needs precisely. Risk

and compare. We are comfortable with the ideathat we will break things in testing, because the end result of doing so is that we can make a decision more quickly and with more good information available
