中文摘要：

针对普通被动测试方法的测试目标难以主动控制、被动机制下获取的测试数据实用性和充分性都较低等难点，提出了新的测试方法。建立测试数据获取的被动机制，对数据驱动的准被动测试法和目标驱动的准被动测试法的处理流程分别进行了设计，创建了针对仿真系统测试过程的z模型，并对z模型中各环节的技术关键给予设计解释。实践证明，这种测试方法能够发现其他测试方法难以发现的bug，对于仿真系统z模型相比其他模型有多方面的优势。

英文摘要：

The target of passive testing is difficult to control, and the test data from passive testing is little practicability, and sufficiency of data is not enough. Through making passive approach to test data from practical production, this paper put for- ward passive testing based on data and passive testing based on target to overcome these difficulties. Z model was specifically applicable to developing of simulation system, as well details of Z model was show clearly. It proves that passive testing based on data and passive testing based on target can find some bugs which are difficult to be found by other method of testing. Z model has many advantages compared with other models.
