1. The Golden Master technique is used to generate system tests by capturing outputs without changing production code, generating random inputs and persisting input/output tuples, writing a test to check the system under test against persisted data, and committing the test. 2. ApprovalTests is an open source assertion library that can aid in unit testing. 3. The Gilded Rose kata involves updating item quality and sell-by dates each day according to various rules like certain items like aged brie and backstage passes increasing in quality over time.

- 3. Coding Dojo Mindset ● We are here to learn ● Safe place outside of work ● Need to slow down ● Focus on doing it right ● Noncompetitive, collaborative, fun environment
- 4. Practice session ● One laptop with a functional dev. env. is connected to a projector ● Two developers pair program on the laptop. The others are watching the code changes. ● Every 7 minutes, one developer leaves the laptop and the next one from the room takes his place.
- 8. Gilded Rose Kata ● All items have a SellIn value which denotes the number of days we have to sell the item ● All items have a Quality value which denotes how valuable the item is ● At the end of each day our system lowers both values for every item
- 9. Gilded Rose Kata ● Once the sell by date has passed, Quality degrades twice as fast ● The Quality of an item is never negative ● "Aged Brie" actually increases in Quality the older it gets
- 13. Practice time!
- 14. Retrospective ● What did you learn today? ● What happened as expected? ● What surprised you? ● What do you plan to use at work?
