Testing is a very important area in the software development. However, this area needs more effective tools with a higher level of automation with are more comprehensive than the tools available today. A large part of the techniques that do generation of test cases use explicity or implicitly decision tables as an auxiliary tool. This dissertation aims to develop a semi-automatic process that has as outputs tests suites that were generated using decision tables. These suites must be appropriate for the test automation tools. To achieve these goals were implemented: (i) an decision table editor, (ii) a automatic generator case test, and (iii) an automatic test scripts generator of the FEST framework. After it was necessary evaluate the benefits that these tools could bring for the test area, both in the planning (generation of valued test cases from semantic test cases) and in the execution of test cases. The evaluation was based on a series of examples involving specific elements of human interfaces, and also in application to real software.
