从PHPV 4迁移到PHP v5时，必须要注意这些在PHP V 4中完全不可用的语言特性，还必须重新验证类来查看可以怎样使用这些类。
When migrating from PHP V4 to V5, it's important to look at language features like these, which were wholly unavailable in V4, and to re-examine your classes to see how you can use them.
调用处理程序类是处理所有数据验证逻辑的地方。
The invocation handler class is where all of the data validation logic is handled.
例如，当创建用例和支持性工件时，一个单元测试人员可以恢复合适的类来验证。

多数web层的测试框架遵循黑盒测试方式，开发者用web组件编写测试类来验证渲染的HTML输出是否符合预期。

这一点可以通过随调用消息输出的服务类名称得到验证。
This can be verified by the service class name printed with the invocation message.
组件测试是基本的测试，这些测试将验证不止一个类，且通常依赖于外部依赖项，如数据库。
Component tests are essentially tests that verify more than one class and, typically, rely on external dependencies such as a database.
改进数据格式验证过程的第一步是将所有的验证逻辑都移至一个助手类中，其它方法可以按需从这个类上调用验证逻辑。
The first step to improving our data-format validation procedure is to move all the validation logic into a single helper class, from which other methods can invoke it as needed.
