regression testing is the process of validating modified software to provide confidence that the changed parts of the software behave as intended and that the unchanged parts have not been adversely affected by the modifications. The goal of regression testing is to reduce the test suit by testing the new characters and the modified parts of a program with the original test suit. regression testing is a high cost testing method. This paper presents a regression testing selection technique that can reduce the test suit on the basis of Control Flow Graph (CFG). It import the inherit strategy of object-oriented language to ensure an edge’s control domain to reduce the test suit size effectively. We implement the idea by coding the edge. An algorithm is also presented at last.

The emphasis of component system regression testing is retesting of the event interaction between updated components and other components in a system.A component system regression testing method based on a new component testing association model （CTAM） is ***,the modification-affected component groups are identified by the impact analysis on CTAM,and each component in this group is assigned with an influence ***,previous test cases are selected according to the influence degree,to generate the minimal regression test *** with traditional methods,CTAM is derived from the statistic on the interactive events that occurred in previous test executions,and focuses on the complicated relationship between components,which is more applicable to the component system regression testing.

In the process of software testing, it requires a lot of manpower and time to design test *** cases of high similarities can be modified to reduce the workload of test case design, and improve the test efficiency. A test case reuse method based on function calling path is proposed. According to the change functions and the correlation functions it determined the changed path to be tested. It selected the function calling path which has high degree of similarity with the changed path to be tested from the original function calling path set. The collection of reusable test cases were determined according to mapping relationship between function calling path and test case, and the reusable test cases were modified to cover the change paths. Experimental results have validated the effectiveness of the proposed test case reuse method, and further reduce the workload of designing test cases and regression testing costs.

Model-based testing can use a model to test a concrete program’s implementation. When the model is changed due to the evolution of the specification, it is important to maintain the test suites up to date, such that it can be used for regression testing. A complete regeneration of the whole test suite from the new model,although inefficient, is still frequently used in practice. To address this problem effectively, we propose a test case reusability analysis technique to identify reusable test cases of the original test suite based on graph analysis,such that we can generate new test cases to cover only the change-related parts of the new model. The Market Information System(MIS) is employed to demonstrate the feasibility and effectiveness of the proposed *** experimental results show that the use of our method saves about 31.5% test case generation cost.
