In order to construct general purpose used software integration testing platform architecture

three kinds of vessels are designed. Firstly

through using mixed type data vessels as basic data type to access software interfaces

various types of input and output data are treated uniformly for compatibility. Secondly

with the adoption of part connection vessels to encapsulate software components

the function pointer portions of the vessels are utilized to call the entry module of the software component indirectly. Finally

under the support of component interfaces accessing vessels

the input and output interface variables of components being tested are accessed indirectly

which decouples the test platform from the test objects. On this basis

the testing platform architecture is divided into variable initialization module and constant periodic scheduling control module

which realizes logical isolation between the platform and the software under test. Practical application analysis demonstrated that the software integration test platform is portable and reusable across software via proper configuration of various portions of the vessels.
