And at the GoddardSpace Flight Center in Maryland, NASA hardware and systems engineers tested thecars' mechanical components to identify conditions that could unexpectedly openthe throttle.
常常被忽视的一种测试用例是边界条件：当遇到不正常的输入时，代码会做什么？
Some of the oft-neglected test cases are boundary conditions: what will your code do when faced with unusual input?
该方法可以在装置正常工作的条件下，进行多次阶跃测试，因而在工程上是比较实用的。
The notable characteristic of this method is that the multi step test can be done under the normal operation, and that it has strong practicality on the real engineering.
通过IEC61215性能测试和UL 1703的安全测试，保障了组件可以在各种恶劣的环境条件下正常工作。
Performance test IEC61215 and safe test UL1703 ensure that solar modules normally work although they are under the atrocious weather condition.
将网站放在不同的分辨率下、不同的电脑平台上以及不同的浏览器上进行测试，尽最大可能确保网站在各种条件下都能够正常显示。
View it in different screen resolutions, various computer platforms and different browsers. Take the time and effort to ensure that a Web site will look good no matter how it is viewed.
