Graph of cause and effect is an effective software testing method,which is suitable to design the testing cases that the combination of multiple conditions generated multiple actions.The graph of cause and effect is ultimately transferred into decision table.In decision table,with the increasing number of the input data,the testing cases grow linearly.When the number of input data is lager,the corresponding produced decision table must has great scale and the testing cases will be excessive.Moreover,some conditions and their values given from specification introduction of the project is unnecessary.Thus,in this paper,the graph of cause and effect is simplified using rough set.And an instance is used to illustrate the reasonableness and applicability of the simplified method.After simplified,conditions and their values have no more redundancies in the decision table derived from the graph of cause and effect.That lessens the number of the test cases far and away.So the testing is more brief and effective.
