METHOD AND APPARATUS FOR VERIFYING SPECIFICATION, AND COMPUTER PRODUCT

An apparatus for verifying a specification includes a use-case extracting unit, a first setting unit, an operation extracting unit, a second setting unit, and a determining unit. The use-case extracting unit extracts an unprocessed use case from specification data. The first setting unit sets a condition based on a precondition, a postcondition, and an invariant condition for the use case. The operation extracting unit selects an event flow of an unprocessed path from the specification data and extracts an unprocessed operation (description) from the event flow selected. The second setting unit sets a precondition and a postcondition for the operation based on the extracted operation (description). The determining unit determines whether the invariant condition is valid.
