Whether the PFR function can be timely and effectively played is an important factor for guaranteeing the operation safety of the server. Therefore, the server test phase needs to test for the function implementation condition, the working stability and the abnormal condition handling of the PFR.

The PFR test has higher specialty, needs testers to deeply understand the requirements of test documents, uses corresponding tools to test, and has the disadvantages of complicated test steps, long consumed time and large labor investment.

And manually installing corresponding software such as test software, a driver and the like, and configuring an operating system environment. And then, triggering abnormal conditions at manual positions according to the test requirements, and collecting corresponding test data for analysis. Aiming at the problems of high specificity and complex tools of PFR testing, the method can be used for solving the problems by adopting a function integration mode. Such as CN202110964736.0.
