A technique for generating an executable document that includes information for validating generated code is provided. The technique can include mapping an assumption to a portion of generated code, the portion containing functional code that is related to implementing the assumption, the mapping allowing at least the portion to be validated with respect to the assumption. The technique can include generating the executable document, where the executable document includes the mapping, and where the generated document validates the at least the portion of the generated code, where validating the at least the portion of the generated code validates the generated code.
