Single objective Test Case Prioritization has the onesided disadvantage.In order to solve this problem,the multiobjective test case prioritization is proposed.The multiobjective test case prioritization is to give the execution order of test cases based on multiple optimal objectives,so as to improve the efficiency of software testing and reduce the cost of regression testing.On the basis of introducing the basic concept of multiobjective test case prioritization,the main methods to solve the problem are summarized and the existing problems are pointed out.Finally,the future research direction of multiobjective test case prioritization is given.
