Abstract: This paper studies the attribute of test sequence inherent in the parallel test, and proposes the parallelizability of test sequence. The parallelism solves the problem that the difference of test efficiency improvements in parallel test can not be explained. Also this criterion can guide the engineering through the selection of instruments resource in the Automatic Test System(ATS). Experimental result shows that the parallelizability is the quality inherent in the test sequence, and the conception of parallelism is valid.

Key words: parallelizability, parallel test, test sequence

摘要： 针对并行测试系统中不同测试序列测试效率提高存在差异的现象，分析、研究测试序列可并行性的概念，以描述测试序列在并行测试中的固有属性。建立的可并行度指标解决了测试序列测试效率提高不同无法解释的难题，对并行测试系统开发过程中仪器资源的选取与确定具有指导意义。通过测试序列实例，验证了可并行性是测试序列的固有属性，说明了可并行度概念的合理性。
