Alex ran the session broadly as I did in Cambridge, as a metaphor:
- the kata on each computer represents a feature for a product, with the product being the sum of all those features
- the tests for each computer (which are visible to all computers) use a simple traffic light display, green light if all tests pass, red light if some tests are failing, yellow light is the tests can't be run (eg syntax error)
- if everyone's tests pass all the lights will be green which represents a stable releasable build
- if any computer's light is not green, the build is broken and can't be released to the client
Alex also reports that one of the highlights (and aims) of his session was getting all our developers working together.
Thank you Alex.
