Our paper is a simple attempt to work for the demand of an appropriate and relevant metrics and in this paper, weve proposed some integration metrics for the measurement of complexity of a software. Software measurement is a titrate impute of a characteristic of a software product or the software process. Software testing metrics or software test measurement is the quantitative indication of extent, capacity, dimension, amount or size of some attribute of a process or product. The key difference is that a metric is based on standardized procedures, calculation methods and systems for generating a number.
