Abstract: With the concern of concurrent system testing increasing recently,new and different test tools are constantly coming into the market.For software test engineer,the ability of selecting test tools correctly has become the determining factors of testing efficiency.Because concurrent system test tools are not as well-known as those traditional test tools,we designed a recommendation approach based on ontology to promote concurrent system test tools for users.The recommendation approach recommends concurrent system test tools through three modules to improve test efficiency:the types of concurrency bugs,the features of the program to be tested and the requirement of users.

Key words: Concurrency bug,Ontology,Testing tool recommendation
