The invention provides a method for generating test cases in a batch mode. The method comprises the steps that a parameter file which is only used for storing test data is analyzed, a group of keywords defined by a test tool based on one test case are applied mechanically to constitute a file capable of storing a batch of test cases, the file for the test cases can be led in the test tool and is carried out. When the method for generating the test cases in the batch mode is used, under the conditions that parameter combinations of a tested function are multiple and the data size is big, the labor cost can be obvious saved, and meanwhile omission occurring in the process of the test cases are established one by one manually can be avoided.
