珀西瓦爾編著的《Python測試驅動開發（影印版
）（英文版）》這本實用指南帶你從頭至尾經歷一個
真實Web應用開發的全過程，展示了Python測試驅動
開發（TDD）的優越性。你將學到如何在應用程序各
部分被構建出來之前就編寫並運行測試，然後開發最
少量的代碼就讓這些測試運行通過。結果得到什麼？
能夠運行的簡潔代碼。
在書中，你將學到Diango、Selenium、git、
iQuery和Mock的基礎知識，另外還有現代Web開發技
巧。如果你準備將自己的Python技術提升到下一個層
次，這本書清楚地展示了測試驅動開發是如何提倡簡
單設計並增進信心。
深入測試驅動開發工作流，包括單元測試／編碼
周期循環和重構
為類和函數使用單元測試，並為瀏覽器內的用戶
交互使用功能測試
學習何時與如何運用mock對像，以及單獨和集成
測試的優缺點
在開發用服務器上測試以及自動化部署
將測試運用到網站集成的第三方插件上去
使用一個持續集成環境來自動運行測試

2. Extending Our Functional Test Using the unittest Module
Using a Functional Test to Scope Out a Minimum Viable App
The Python Standard Library's unittest Module
Implicit waits
Commit
3. Testing a Simple Home Page with Unit Tests
Our First Django App, and Our First Unit Test
Unit Tests, and How They Differ from Functional Tests
Unit Testing in Django
Django's MVC, URLs, and View Functions
At Last！ We Actually Write Some Application Code！
urls.py
Unit Testing a View
The Unit-Test/Code Cycle
4. What Are We Doing with All These Tests？
Programming Is like Pulling a Bucket of Water up from a Well
Using Selenium to Test User Interactions
The "Don't Test Constants" Rule, and Templates to the Rescue
Refactoring to Use a Template
On Refactoring
A Little More of Our Front Page
Recap: The TDD Process
S. Saving User Input
Wiring Up Our Form to Send a POST Request
Processing a POST Request on the Server
Passing Python Variables to Be Rendered in the Template
Three Strikes and Refactor
The Django ORM and Our First Model
Our First Database Migration
The Test Gets Surprisingly Far
A New Field Means a New Migration
Saving the POST to the Database
Redirect After a POST
Better Unit Testing Practice: Each Test Should Test One Thing
Rendering Items in the Template
Creating Our Production Database with migrate
6. Getting to the Minimum Viable Site
Ensuring Test Isolation in Functional Tests
Running lust the Unit Tests
Small Design When Necessary
YAGNI！
REST
Implementing the New Design Using TDD
Iterating Towards the New Design
Testing Views, Templates, and URLs Together with the Django Test Client
A New Test Class
A New URL
A New View Function
A Separate Template for Viewing Lists
Another URL and View for Adding List Items
A Test Class for New List Creation
A URL and View for New List Creation
Removing Now-Redundant Code and Tests
Pointing Our Forms at the New URL
Adjusting Our Models
A Foreign Key Relationship
Adjusting the Rest of the World to Our New Models
Each List Should Have Its Own URL
Capturing Parameters from URLs
Adjusting new_list to the New World
One More View to Handle Adding Items to an Existing List
Beware of Greedy Regular Expressions！
The Last New URL
The Last New View
But How to Use That URL in the Form？
A Final Refactor Using URL includes
