Software testing is a delicate combination of art and science. A great deal of sound theory has been developed, but in practice this theory is often ignored. Much testing is ad hoc, especially for consumer level software, where time to market can be the most critical factor in development. In this case, tests are often aimed primarily at demonstrating specific functionality of the application being tested, such as showing that an inventory program accepts and saves records of new products received.

解决复杂性和信任问题的窄谱软件测试

软件测试是艺术与科学的巧妙结合。已经发展了大量合理的理论，但在实践中这一理论常常被忽视。许多测试是临时的，特别是对于消费级软件，在这种情况下，上市时间可能是开发中最关键的因素。在这种情况下，测试通常主要旨在演示被测试应用程序的特定功能，例如显示库存程序接受并保存收到的新产品的记录。
