rather than long-lived feature branches f. BUILD A FAST AND RELIABLE AUTOMATED VALIDATION TEST SUITE i. Slow and periodic feedback kills – larger batch sizes compound effort needed to identify causes applications and services g. CATCH ERRORS AS EARLY IN OUR AUTOMATED TESTING AS POSSIBLE i. A test suite’s goal is to find the error as early as possible, in the fastest category as possible ii. Later automating tests that genuinely validate business goals k. INTEGRATE PERFORMANCE TESTING INTO OUR TEST SUITE i. Discovering performance issues in production is too late ii. Validate performance with automated

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 of API

without requiring changes to the whole ball of EA.  It has a robust, automated regression test suite, so that new development does not cause expensive break-fix activity.  It has good monitoring tools

tighten up our change controls… what’s preventing us from getting there?”  “That change management tool is impossible to use. There’s a million mandatory fields and most of the time, the drop down boxes
