Debug Builds: A New Hope (Droidcon MTL 2015)

The Cash team at Square moves fast. Really fast. Learn about the tools that we use to eliminate external dependencies and move as fast as possible.

In this talk, I’ll show you how to:
• Quickly verify all of the states of your app by eliminating the server.
• Build and test a server-supported feature before the server is ready.
• Add shortcuts to accelerate your edit-verify cycle.
• Make it easy to submit bug reports with screenshots & full context.
