RESUMO

Testing criteria are useful in the task of test case generation and they are predicates to consider the testing activity ended, that is, to determine the adequation of a test set. They require the execution of paths in the program that exercise some elements such as statements, decisions, definitions and uses of variables. Selecting paths and generating automatic test data for a given structural criterion are very hard activities since it is not always possible to determine a data that executes a particular path in a program; it is even undecidable whether this data exists, that is, whether the path is feasible. This makes those activities difficult and increases the cost of testing. Several researches attach importance to strategies that minimize the number of infeasible selected paths to cover structural criteria. The goal of this work is to study, propose and offer strategies to select paths and mechanisms to automate and validate these strategies to be used with structural criteria. The proposed strategies consider different characteristics of programs for paths selection with the goal of: increasing the efficacy, easing the test data generation and reducing the effects caused by infeasible paths in the software testing. A structure to represent these strategies are presented. A module that implements this structure is described. This module is an extension to the testing tool named Poke-Tool, that supports different structural testing criteria. It was used to evaluate a strategy that proposes to minimize the number of infeasible selected paths. This application was guided to the detection of some program structures for which the evaluated strategy did not meet its objective and pointed out some results about the efficacy of the generated test data
