Method and device based on virtual machine creation software performance testing environment

Abstract

The present invention relates to a virtual machine, and specifically discloses a method and apparatus for creating a software performance testing environment based on a virtual machine, wherein the method comprises: in response to obtaining a hard disk read/write request triggered by a virtual CPU of the virtual machine, notifying a virtual CPU scheduler to record a CPU time quota t1 already consumed by the virtual CPU in a current CPU schedule period; in response to detecting completion of hard disk read/write processing corresponding to the hard disk read/write request, predicting a hard disk read/write latency t corresponding to the hard disk read/write request in a target environment; notifying the virtual CPU scheduler to determine a CPU time quota already consumed by the virtual CPU in the current CPU schedule period based on the recorded CPU time quota t1 and the hard disk read/write latency t; and adjusting a system clock of the virtual machine based on the determined CPU time quota already consumed by the virtual CPU in the current CPU schedule period. The method according to the embodiments of the present invention may obtain, in the created software performance testing environment, a software performance testing result consistent with the result obtained under a highly configured server in the target environment.

Description

technical field [0001] The present invention relates to a virtual machine, and more specifically, to a method and device for creating a software performance testing environment based on a virtual machine. Background technique [0002] Software performance testing is an important part of software quality control. In the standard software development process, each software version needs to go through multiple rounds of performance testing before it is released or delivered to customers to ensure the normal operation of the software in the operating environment after delivery. Reliable software performance testing requires that the tested hardware environment is consistent with the hardware environment where the software is finally deployed and operated. However, in most cases, the target hardware configuration of the software product is relatively high, and the hardware environment of the existing software test platform of the software developer (or software delivery party) o...

Problems solved by technology

However, this method has the following three disadvantages: 1. More test cases are required for actual measurement; 2. The quality of the prediction is particularly dependent on the experience and expertise of the testers; 3. Considering the natural uncertainty of the prediction itself, Conservative performance estimates are often used in performance prediction, resulting in inaccurate performance evaluations, resulting in additional software development costs or software operating costs

However, such a virtual mach
