In this paper, we present a case study where two code generators for the B-Method were validated using software testing techniques. Our testing strategy is a combination of Grammar-Based Testing (GBT) and Model-Based Testing (MBT) techniques. The strategy consists of two steps. In the first step, grammar-based coverage criteria are used to generate a wide and meaningful set of test input models to validate the parsing capabilities of the code generators. In the second step, a MBT tool is used to validate the correctness of the output produced by these tools. The MBT tool generates a set of tests based on the same input model used by the code generation tools. The generated code is considered correct (consistent with the input model) if it passes this set of tests. Using this testing strategy, we were able to find problems in both code generation tools with moderate effort.
