Ebook Description

Many businesses and organizations depend on older high-value PHP software that risks abandonment because it is impossible to maintain. The reasons for this may be that the software is not well designed; there is only one developer (the one who created the system) who can develop it because he didn’t use common design patterns and documentation; or the code is procedural, not object-oriented. With this book, you’ll learn to identify problem code and refactor it to create more effective applications using test-driven design. What you’ll learn What refactoring is and why you need to refactor code What test-driven design is and why you need to test your code How to write unit and functional tests with PHPUnit and Selenium Remote Control (RC) How to detect “bad smells” in PHP code, and refactor them using test-driven design How to refactor a large procedural application affected by many bad smells Who this book is for This book is for PHP developers, businesses, and developers relying on legacy PHP apps.
