An overview on test generation from functional requirements

Abstract

Despite the fact that the test phase is described in the literature as one of the most relevant for quality assurance in software projects, this test phase is not usually developed, among others, with enough resources, time or suitable techniques. To offer solutions which supply the test phase, with appropriate tools for the automation of tests generation, or even, for their self-execution, could become a suitable way to improve this phase and reduce the cost constraints in real projects. This paper focuses on answering a concrete research question: is it possible to generate test cases from functional requirements described in an informal way? For this aim, it presents an overview of a set of relevant approaches that works in this field and offers a set of comparative analysis to determine which the state of the art is.
