This part of the book discusses various types of tests. The chapters progress from the types of tests closer to code to those closer to users. White box testing, which tests the programs by having an internal knowledge of program code, is discussed in Chapter 3. Black box testing, which tests the product behavior by only knowing the external behavior as dictated by the requirements specifications, is discussed in Chapter 4. As software gets developed in a modular fashion and the modules have to be integrated together, integration testing is covered in Chapter 5. System and acceptance testing, which tests a product completely from a user's perspective in environments similar to customer deployments, is discussed in Chapter 6. Performance testing, which tests the ability of the system to withstand typical and excessive work loads, is discussed in Chapter 7. Since software is always characterized by change and since changes should not break what is working already, regression testing becomes very important and is discussed in Chapter 8. As software has to be deployed in multiple languages across the world, internationalization testing, the topic of Chapter 9, comes into play. Finally, adhoc testing, in Chapter 10, addresses the methods of testing a product in typical unpredictable ways that end users may subject the product to.
