Software Coverage Test Method Based on Dynamic Assignment of Pile Function

摘要:

针对软件单元覆盖率测试中需多次变更被测函数输入激励的需求,以Testbed为测试平台,结合变量的变化特性,提出一种输入变量激励可动态更新的桩函数赋值方法。实验结果表明:该方法有效解决了输入激励变化的被测函数测试覆盖率低的问题,提高了用例设计的准确性和代码测试覆盖的充分性。

Abstract:

In view of the demand of changing the input excitation of the tested functionfor many times in software unit coverage test, taking Testbed as the test platform andcombining the variable variation characteristics, a method of pile function assignment withdynamic updating of input variable excitation is proposed, The experimental results showthat the method can effectively solve the problem of low test coverage of the function undertest with variable input excitation. The accuracy of test case design and the sufficiency ofcode test coverage are improved.
