Graph queries for analyzing the coverage of requirements by test cases
Shingo Ariwaka · Proceedings/Proceedings of the ... International Conference on Software Engineering and Knowledge Engineering · 2021
We study the applicability of graph queries to the coverage analysis of test cases for requirements specifications.First we show that when the similarity degrees between requirements specifications and test cases are available, they can be represented in the form of a graph.Then we identify several queries that are useful for extracting coverage information and show that all these queries can be written in the Cypher query language, a common graph query language.In a case study we apply these queries to data obtained from a real-world project in industry.The results of the case study show that coverage information can be retrieved in reasonable time.We also compare the graph queries with SQL queries with respect to conciseness and processing time.
