An automated software class specification validation tool automatically determines, for functions defined in a function definition section of a class specification, whether the function is properly declared throughout one or more other sections of the same class specification. Further, it can be determined whether variables, i.e., attributes, parameters, and local variables, associated with respective functions in the function definition section are properly specified throughout one or more other sections of the same class specification. The functions and variables that are validated include attributes and functions that are specified for structures and nested classes defined in a defined type section of the class specification. The validation tool is accessible over a network via a web page, and results of the validation process are also displayed on a web page.
