Device driver testing

If you have mapped the device memory directly into your memory space and device driver reads and writes to device memory as it is its own memory, it gets a little bit complicated. Using automated testing tools, now you have to watch values of pointers and define pass/fall criterieas according to the values of these pointers. if you are reading a value from memory, you have to .  · As for some unique functions of a specific device driver, we do not need to pay too much attention to it and only assure that its minimal functionality is correct. I assume this kind of test suite should leverage high level applications to verify functional correctness of the device driver instead of low level unit test.  · To determine the driver version for a particular piece of hardware with Device Manager, use these steps: Open Start. Search for Device Manager and click the top result to open the www.doorway.ruted Reading Time: 3 mins.

Provisioning a target or test computer is the process of configuring a computer for automatic driver deployment, testing, and debugging. To provision a computer, use Microsoft Visual Studio. A testing and debugging environment has two computers: the host computer and the target computer. The target computer is also called the test computer. You develop and build your driver in Visual Studio on the host computer. The Driver Install test category includes tests that uninstall and reinstall a driver several times to test install functionality. The tests initiate I/O testing against the driver and device after each reinstall. The tests are designed to improve the overall experience for end users who need to install and reinstall a device driver or a device. Test your driver and device on as many different hardware configurations as you possibly can. Varying the hardware can help you find conflicts between devices and other errors in device interactions. For example, you should test your driver and device on computers that have different processor architectures and on computers that are running bit and bit versions of Windows.

However, they generally don't test how individual pieces work together as a whole, or capture the performance of an application running on a real device. Developing device drivers is important for innovative consumer electronics because device driver implements key functionalities of new devices. The driver tests outlined below are currently only applicable to Zigbee and Z-Wave devices. Testing is not required, but can help identify and address bugs.
