I ll start this month with a look at one of the most popular and easy additions to a java developer s quality assurance toolkit : test coverage measurement 在这个月，我将首先看看java开发人员中最流行也是最容易的质量保证工具包：测试覆盖度量。
Now that i ve established some of the ways test coverage reports can lead you astray , consider these best practices for using them to your advantage 现在我可以断定对测试覆盖报告的一些使用方法会将您引入歧途，下面这些最佳实践可以使得测试覆盖报告可以真正为您所用。
So that ' s more tests , more time for developers to run the test suite , and more chances of missing code coverage , especially when different modes interact 也就是要写更多的测试，开发者要花更多的时间来运行测试套件，并且更有可能达不到代码的测试覆盖度，特别是当不同模式相互作用时。
A test coverage measurement is obtained by exercising a code base with a test harness and capturing data that corresponds to code having been " touched " throughout the lifetime of the test process 通过用一个测试工具执行代码库并捕获整个测试过程中与被“触及”的代码对应的数据，就可以获得测试覆盖度量。
Therefore , knowing whether code has been tested , and seeing the actual test coverage numbers , can allow developers and managers to more accurately predict the time needed to modify existing code 因此，知道代码有没有被测试，并看看实际的测试覆盖数值，可以让开发人员和管理人员更准确地预知修改已有代码所需的时间。
Based on program partition mechanism , a new oo coverage metric is proposed , which is superior to traditional structural coverage metrics . 4 . object - oriented software metrics . we provide more than twenty important metrics 本文提出了一种新的基于块的面向对象覆盖度量，可以比传统的结构化覆盖度量获得更精确的测试覆盖数据。
" i use jtest for coding standards , unit test generation , test coverage , and both static and dynamic analysis . the new version is even more automated and i plan to use the team interface to share results with other developers and testers on my team . 用于编码标准、单元测试生成、测试覆盖，以及静态和动态分析。新的版本更加自动化，我打算利用小组接口于小组中其他的开发人员和测试人员共享结果。 ”
If you re focusing on code quality , you need to understand exactly how test coverage tools work , as well as how they don t ; then you ll know how to use these tools to obtain valuable information , rather than just settling for high coverage goals , as many developers do 如果您关注的是代码的质量，就必须精确地理解测试覆盖工具能做什么，不能做什么。然后您才能知道如何使用这些工具去获取有用的信息。而不是像许多开发人员那样，只是满足于高覆盖率。
Because the events sequences getting from the tfg only including a series of the events which can cause the transition of the state , and not containing the interactive information among all types of objects and other events which can ’ t cause the transition of the state , we can add the detailed interactive information in the events sequence of transition of the state and described it as uml sequence ; then , it is difficulty for analyzing the interactive events in uml sequence and may not fully cover the test 接着使用uml顺序图描述所得到的测试序列,并在uml顺序图中加入详细的对象交互信息;然后,使用具有独特的树型结构并且容易实现分支或路径覆盖的ircfg图描述uml顺序图中的消息事件交互信息,构造与uml顺序等价的ircfg图。最后,通过本文提出的测试覆盖标准覆盖ircfg图得到最终的测试用例。我们在文中还通过一个实例系统?饮料销售机系统来进一步说明该测试模型的有效性。
We have compared the differences of traditional software test and object - oriented software test . at the same time , the traditional coverage measurement criterion ’ s deficiency are explained when it is used to measure the coverage of object - oriented software test . we have improved on the segment - based object - oriented testing coverage measurement criterion 我们还比较了传统软件测试与面向对象软件测试之间的差别,同时说明了传统的软件测试覆盖度量指标在用于度量面向对象软件测试覆盖时的不足之处,并对基于段的面向对象覆盖指标进行了改进。
