测试驱动开发(TDD)是以测试作为开发过程的中心，它坚持，在编写实际代码之前，先写好基于产品代码的测试代码。开发过程的目标就是首先使测试能够通过，然后再优化设计结构。测试驱动开发式是极限编程的重要组成部分。XUnit，一个基于测试驱动开发的测试框架，它为我们在开发过程中使用测试驱动开发提供了一个方便的工具，使我们得以快速的进行单元测试。XUnit的成员有很多，如JUnit，PythonUnit等。今天给大家介绍的CppUnit即是XUnit家族中的一员，它是一个专门面向C++的测试框架。-test-driven development (TDD) is tested as the center of the development process, it maintained, in the preparation of the actual code, before getting the product code based on the test code. The goal of the development process is the first to test passed, and then optimize the design of the structure. Test-driven development is an important limit programming components. XUnit, one based on test-driven development of the testing fr a mework, it for us in the process of developing the use of test-driven development provides a convenient tool allow us to conduct rapid testing modules. XUnit many of the members, such as JUnit, PythonUnit other. Today, we introduce to the CppUnit XUnit family is the one. It is a special test for C fr a mework.
