An order-assigned strategy of classes integration testing based on test level

It is very important how to find the test order of classes in OO programs to make the test work reduced. In this paper, an order-assigned strategy of classes integration testing is presented. It considers not only the static dependency but also dynamic dependency relation between classes in OO programs. Based on it, the testing level of all classes are defined and ordered. A testing level order automatic generating tool - TLOGOS, implements the above strategy. This tool has been used in YSS2000 Electric Power Monitor&Control System, and reduced the test works obviously.
