In this paper, a methodology that diagnoses errors in software is proposed. This is based on the combination of Design by Contract, Model-based Diagnosis and Constraint Programming. Contracts are specified by using assertions. These assertions together with an abstraction of the source code are transformed into constraints. The methodology detects if the contracts are consistent, and if there are incompatibilities between contracts and source code. The process is automatic and is based on constraint programming.
