Abstract: How to provide cost effective strategies for software testing has been one of the research focuses in software engineering for a long time. Many researchers in software engineering have addressed the effectiveness and quality metric of Software Testing, and many interesting results have been obtained. However, one issue of paramount importance in software testing-the intrinsic imprecise and uncertain relationships within testing metrics- is left unaddressed. To this end, a new quality and effectiveness measurement based on fuzzy logic was proposed. The software quality features and analogy-based reasoning were discussed, which can deal with quality and effectiveness consistency between different test projects. Experimental results were also provided to verify the proposed measurement.
