存在测试 meaning in English
existence test
Examples
- Are existence tests introduced with exists
通过exists引入的存在测试。 - When importing test lists , if there is a test list id conflict
导入测试列表时，如果存在测试列表id冲突 - When importing test run configurations , if there is a test run configuration conflict
导入测试运行配置时，如果存在测试运行配置冲突 - In addition , the author also research in general detection optimal algorithm used by fault diagnosis system , these detection optimal algorithm can classify into two types , the first type is that algorithm must be able to find the ptvs ( parallel test vector ) which has the best condensing index p under fault location precision request , these algorithm include woa optimal algorithm , true / compliment optimal algorithm ; the second type is that algorithm must be able to find the ptvs which has the best fault location precision under the condensin index p request . these algorithms include minimum weight value optimal algorithm . but these general detection optimal algorithms have a lot of flaw in test time cost or low fault coverage rate
本文作者还对测试优化算法进行仔细研究，研究结果表明测试优化算法可分为两类，第一类是在满足给定故障定位精度的前提下寻找能够实现最优紧凑性指标p的ptvs (并行测试向量集) ，如true compliment算法；第二类是在满足给定紧凑性指标的前提下寻求能够实现最优故障定位精度的ptvs ，如极小权值优化算法，研究结果还显示这些常规的算法存在测试时间长、故障覆盖率低的缺点。
