Abstract

The invention discloses a cloud platform chaos test method and device, and the method comprises the steps: obtaining a test result of a kth round of concurrent test of a to-be-tested cloud platform after a fault is injected into the to-be-tested cloud platform, and carrying out the statistics of an actual error rate of the kth round of concurrent test; estimating the predicted error rate of the (k + 1) th round of concurrent test by using the actual error rate of the kth round of concurrent test; judging whether the prediction error rate of the (k + 1) th round of concurrent test is greater than a preset threshold value or not; if yes, reducing the concurrent request amount; when the value is smaller than the preset threshold value, increasing the concurrent request quantity; and when the concurrence request quantity is equal to the preset threshold value, determining the concurrence request quantity of the kth round of concurrence test as the criticality of the to-be-tested cloud platform under the fault. According to the method, the concurrent request quantity of the current test is adjusted by using the historical test result, and the concurrent request quantity is adaptively adjusted after the fault is injected, so that the performance criticality of the cloud platform after the fault is injected is accurately tested, and the performance degradation condition of the cloud platform after the fault is determined.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a cloud platform chaos testing method and device. Background technique [0002] In recent years, cloud computing has been a hot research direction in the ICT field, and the quality control of cloud platform performance has also attracted much attention. At present, the mainstream open source cloud platform software (such as: OpenStack) generally adopts the microservice architecture. The microservice architecture splits a single software into multiple software services with distinct functions that can be run and deployed independently. It has the characteristics of good scalability, easy deployment, and easy development. The adoption of the microservice architecture is beneficial to reduce the cost of software development and facilitates the combination with the Devops (Development and operations) working mode, but it also introduces new challenges. The software of the microserv...
