Method for determining priority of regression test case based on thermodynamic diagram

The invention provides a method for determining the priority of a regression test case based on a thermodynamic diagram, which comprises the following steps of: on the basis of counting the number of operation times and time of a function when the test case is executed, drawing a visual mode of a function operation thermodynamic diagram or an operation time thermodynamic diagram; a method and steps for determining the priority of each test case during regression testing in an integrated testing stage are provided, so that the priority of each test case can be conveniently and intuitively obtained; and the testing efficiency of regression testing in the integration testing stage is effectively improved. 本发明提供了基于热力图的回归测试用例优先级确定方法，在对测试用例执行时的函数运行次数和时间的统计的基础上，通过绘制函数运行热力图或运行时间热力图的可视化方式，给出了确定集成测试阶段回归测试时各测试用例优先级的确定方法和步骤，可以方便直观地得到各测试用例的优先级；有效提高集成测试阶段回归测试的测试效率。
