Abstract 'Black box test’ is an inspection method of integration arithmetic that directly checks the integral result and ignored the detailed algorithm, and its standard value can be acquired by building a theory flow distribution.That inspection method can be implemented by developing a computer program whose software flowchart and numerical algorithms is introduced.It is showed that the proposed method has solved the problem that unknownintegral model can’t be inspected.The feasibility of this method is demonstrated through comparing test data with available integral inspection method.
