1. A method for testing at least one input/output interface of a computer module of IMA type ( 510 , 610 , 710 , 825 ) comprising a plurality of input/output interfaces ( 515 , 615 , 715 , 830 ) in a device comprising a plurality of computer modules of IMA type, at least one system comprising at least one application being employed by a set of computer modules of the said plurality of computer modules, the said set comprising the said computer module, referred to as first module, and at least one other computer module, referred to as at least one second module, at least one system test being associated with the said at least one system for functionally testing the said set of computer modules according to the said system, this method being characterized in that the said at least one system test comprises at least one elementary system test for functionally testing the said at least one input/output interface of the said first module, and in that it comprises a step of executing the said at least one elementary system test, the said step of executing the said at least one elementary system test being independent of the said at least one second module, and a step of transmitting ( 545 , 640 , 745 , 830 ) at least one result of execution of the said at least one elementary system test to a maintenance computer distinct from the computer modules of the said plurality of computer modules.
