This introduces challenges to existing test suite reduction techniques and makes it unsuitable for readymade software and for large complex software’s. In this study we propose(recommend) a method using sliding window in function calls to achieve better test suite reduction, without accessing the source code and also to reduce the cost of integration testing by taking size, cost and time as motivating factors. Our proposed method provides good result with earliest reduction techniques in literature. Keywords: Function call;integration testing;sliding window;software testing;test case reduction
