Fault injection test scene case model and framework based on service orchestration

Abstract

The invention relates to a fault injection test scene case model and framework based on service arrangement. The case arrangement model describes a test case as a plurality of test flows composed of aplurality of test steps; the test steps and the test flows containing the special test logic are executed by calling the serviced test component, and the framework integrates an existing micro-service arrangement component and a serviced test tool on the basis of the arrangement model. After a user transmits a test case file described by the arrangement model to the test framework, an analyzer inthe test framework analyzes the test case into a workflow file and sends the workflow file to the micro-service arrangement component, and the micro-service arrangement component calls each test service according to the workflow file to execute the test case. Compared with the prior art, the method has the advantages of improving test efficiency, supporting special test logic service and the like.

Description

technical field [0001] The invention relates to the technical field of computer testing, in particular to a fault injection test scenario use case model and framework based on service arrangement. Background technique [0002] With the development of technologies such as network function virtualization and containerization, the topological structure of today's cloud-dependent systems (such systems are often called cloud-native systems) has become more complex, and its reliability is facing severe challenges. Traditional system reliability testing only includes simple fault injection. However, in order to verify the reliability of cloud-native systems, complex test scenarios need to be designed: in the test scenario, it is necessary to inject faults into the target system and simulate a large number of faults on the target system. In addition to user pressure, it is also necessary to continuously collect performance monitoring data and log data of the target system. In the p...

Problems solved by technology

[0003] 1. Different testing tools have different emphases (such as testing tools only used for fault injection and testing tools only used for user stress simulation), and these testing tools can only be used to test the target system one by one during the testing process, and cannot Integrate them together and use them together to achieve a more comprehensive test scenario;

[0004] 2. Existing test tools cannot reflect the process logic of branching, parallelism, waiting, etc., and cannot meet the requirements of more complex test scenarios

However, in the process of using microservice orchestration components (such as conductor) to implement service-oriented testing, the service orchestration files used to execute test cases often contain a large amount of configuration information about services, which is difficult for testers to interpret

In addition, the existing microservice orchestration components cannot implement specific test logic (for example, in the stress test, the business pressure is increased cyclically until the system fails)
