检测装置模拟地面设备发出测试需要的制式信号，同时对发出的制式信号大小进行检测。

Testing device emits a standard signal like the ground equipment, and tests the amplitude of the standard signal.

为了弄清楚这种情况是否也适用于非生物，加州大学圣地亚哥分校的拉蕾·奎因和她的同事们测试了老鼠能否检测到机器老鼠发出的社交信号。

To find out if this extends to non-living beings, Laleh Quinn at the University of California, San Diego, and her colleagues tested whether rats can detect social signals from robotic rats.

其概念为，当你在开发或修改程序代码时，你就要同时开发出相称的测试程序，而不是把它们延后到测试阶段。

The idea is that, as you develop or change code, you develop appropriate verification tests at the same time, rather than postponing them to a later test phase.
