Method and device for testing streaming system

Abstract

The invention provides a method and device for testing a streaming system. The method comprises the following steps: collecting first interface data of modules in the streaming system, obtaining the types of the first interface data, counting the first range of various characteristic values of each type within a first preset time period, collecting second interface data of the modules in the streaming system, and determining whether characteristic values of the second interface data are within the first range or not. According to the method, the data can be collected automatically in real time, and the test requirement of module interfaces with large data volume and dynamic data is met; a checking rule of the interfaces of the modules is generated automatically and can be regulated timely when data or test strategies change, and the interface data of the streaming system which operates for a long time can be checked; test efficiency and test quality are improved greatly, labor cost is lowered, the streaming system is standardized, and problems which are difficult to find by a traditional test method can be found.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a testing method and device for a streaming system. Background technique [0002] When testing a streaming system in the prior art, it is first necessary to manually construct different test cases according to the interface definition format between various modules in the streaming system, including specified input and expected results, and then manually or automatically according to the specified input Verify the results generated by the streaming system with the expected design standards (expected results) to test whether the interfaces between modules can achieve the expected results under legal and illegal conditions. [0003] There are following problems in prior art: [0004] (1) Regardless of manual or automated verification, manual maintenance of test cases is required, including specified input and expected results. Once data or test strategies change, accurate and ef...

AI Technical Summary

Problems solved by technology

[0004] (1) Regardless of manual or automated verification, manual maintenance of test cases is required, including specified input and expected results. Once data or test strategies change, accurate and effective testing cannot be performed;

[0005] (2) For a long-running streaming system, after testing a version of a streaming system according to the constructed test cases, it will be discarded, and it cannot provide long-term stable continuous monitoring and verification testing services;

[0006] (3) Does not support automatic data collection, especially large-scale data collection and dynamic update;

[0007] (4) For a streaming system composed of multiple modules, especially when the data between multiple modules is directly or indirectly related, it is often impossible to verify by using the integration test or system test method after passing the internal interface test. All-in-one automatic verification
