In the U.S. alone, the cost of faulty software ranges in the tens of billions of dollars per year; the costs of inadequate testing infrastructure are estimated between $22.2 and $59.5 billion, one half paid by the developers and the other half by the users. Albeit the criticality of a good testing process (the inadequacy of which would kill many small enterprises, in particular Latin American ones), many times the testing process is misapplied or not applied at all. We provide here some foundations of the discipline of software testing and present fragments of a variation of a test process used successfully by e-Quallity Corporation (a firm specialized in software testing) in commercial projects, defined formally using a small proprietary process definition language. We present also two case studies of projects with Mexican small and medium enterprises showing concrete economic impacts of the use (and misuse) of this testing process.
