JTAPI是由Sun公司提出的基于Java语言的应用程序接口。由于JTAPI是基于Java的应用接口，使得JTAPI的对象独立于操作系统和硬件平台，支持跨平台的应用。JTAPI定义了一套类库，包含电话功能和扩充功能。JTAPI结合了传统的电话服务和Web处理能力，具有较强的功能。但是，基于Java的特性，使得JTAPI在拥有强大功能的同时，也失去了普及和推广的基础。-JTAPI by Sun"s Java language on the application program interface. As JTAPI is a Java-based application interface, JTAPI makes the object independent of operating systems and hardware platforms to support cross-platform applications. JTAPI definition of a set of class libraries, including telephone functions and expansion capabilities. JTAPI combination of traditional telephone services and Web processing capability, and a strong function. However, based on Java, which makes JTAPI the powerful functions, lost popularize and promote the foundation.

这是XMODEM传输协议原代码,测试只能证明错误的存在，而不能表明程序中没有错误。 测试的两个作用是：确定程序中缺陷的存在；有助于判断该程序在实际上是否可用。 软件测试最困难的问题之一是知道何时停止测试(When to stop testing? ) 自己测试自己的程序是不可能的。 当一个软件被测出的缺陷数目增加时，更多的未被发现的缺陷存在的概率也随之增加。 -This XMODEM transfer protocol source code, the test can only be proved wrong there and not show anything wrong procedure. The two test role is : procedures for determining the existence of defects; Contribute to the judge whether the procedure can be used in practice. Software testing the most difficult one of the problems is to know when to stop testing (When to stop testing) testing their own procedures is not possible. When a software detected the increase in the number of defects, more undiscovered flaws in the probability has increased.
