Summary

Steve Freeman and Nat Pryce wrote this for developers who already know the mechanics of test-driven development and want to see it sustained across a whole system rather than a short exercise. Eleven consecutive chapters go to one worked example, an auction sniper application taken from a walking skeleton through to error handling, each feature driven by a failing test written first. Running it at that length lets the book show TDD at two levels at once: acceptance tests driving what the system does from the outside, unit tests driving the objects inside. Mock objects are treated as a design tool rather than a testing convenience, a way to state an object's relationships with its collaborators before they exist. Surrounding chapters cover starting out and then what surfaces later: tests that are hard to read or diagnose, complex test data, persistence, threads, and asynchrony.

Target Readers

• Developers who know the red-green-refactor cycle and want to see it carried across an entire application instead of a kata
• Engineers who reach for mock objects as a testing convenience and want to understand them as a way of designing the relationships between objects
• Teams whose test suites have grown hard to read or to diagnose, looking for the practices that keep them worth maintaining
