Software testing
Overview Although software testing can determine the correctness of software under the assumption of some specific hypotheses (see the hierarchy of testing difficulty below), testing cannot identify all the defects within the software. Instead, it furnishes a criticism or comparison that compares the state and behavior of the product against test oracles—principles or mechanisms by which Get price

Automated Combinatorial Testing for Software
Combinatorial methods have two primary applications in software engineering: Combinatorial or t-way testing is a proven method for more effective software testing at lower cost. The key insight underlying its effectiveness resulted from a series of studies by NIST from 1999 to 2004. NIST research showed that most software bugs and failures are caused by one or two parameters, with Get price
