         * Dev env doesn't usually have long-term or complete sets of cached data.
         * Cache should be agnostic to model changes.
         * Do object structure comparison when pulling from cache.
+        * Testing how your app deals with 'old' data, not the infrastructure.
+5. Writing tests can improve coding habits
+    * Smaller, modular code is testable, 200-line functions aren't.
+    * Write more tests
+        * Discover easily-testable coding patterns.
+        * Functions should perform a *single function*.
+6. Tests are alive
+7. How do I enforce testing on my team?
+    * Most people don't like 2AM fires.
+    * Iterate faster with confidence.
+    * Git pre-commit hooks, stop checkins without tests.
+    * can make it a game.
+    * Public shaming?
+8. How much testing is enough testing?
+    * No simple answer for that.
+9. Junction between Unit and Integration
+    * Difficult areas to test, because behavior is dependant upon environment.
+10. Testing a virgin codebase: 0-100%
+    * You will refactor code as you write tests
+11. Successful strategies
+    * Require unit tests for all code going forward
+    * Reserve time to clear out test debt
+        * Good for new team members
+        * Everyone takes a turn
+    * Establish a good foundation to build on
+    * Every bug is two bugs:
+        * One in the code that broke
+        * One is the test that would/will catch the bug
+12. Test data
+    * Fixtures, mocks, ObjectCreator
+    * Use SQLite
+13. Should I get test data from cache?
+    * No. Adds unnecessary complexity to unit tests.
+    * If tests only succeed with certain caches, probably some code that can be refactored.
+14. Graceful code degredation
+    * Devs need to think outside their dev instance
+    * Service unavailable shouldn't mean your site is unavailable
+    * If failure is catastrophic, you should know *how* and *why* it happened.
+15. Forcing awareness
+    * Code should not be written in such a way that it won't work (at least in some fashion) if certain services or infrastructers are missing/different.
+16. Test infrastructe
+    * Staging should be identical to production.
+    * Run Solr or RabbitMQ on staging, but not dev.
+    * Don't overdo it on logging.
+17. Testing tools
+    * Nose
+    * Coverage
+    * Mock
+.. note:: Code not tested is broken by design
Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
