Non-regression method of a tool for designing a monitoring system of an aircraft engine

A system of non-regression tests of a tool including a processor coupled to a memory storing executable software instructions for designing a monitoring device of an aircraft engine, said designing tool including modules used to build the monitoring device, each module integrating algorithmic functions dedicated to specific tasks and being configured by a set of parameters, each module being adapted to be executed on an input signal to deliver an output signal, the system comprising:

• processing means configured to automatically create an experience base by instrumenting behavior tests upon executing the modules, said experience base including reference input signals, sets of reference parameters, reference output signals, and collections of results of reference executions relating to said modules,
• processing means configured to start again said behavior tests on said modules depending on the corresponding reference input signals and the corresponding sets of reference parameters thus generating test output signals and collections of results of test executions,
• processing means configured to compare said test output signals with the corresponding reference output signals and said collections of results of test executions with said corresponding collections of results of reference executions in order to test the non-regression of the designing tool, and
• processing means configured to, upon executing a module, create the experience base including:
• creating collections of instances of reference modules for the different modules, each module being associated with a collection of instances of reference modules and each instance of reference module being defined by the algorithmic functions of the corresponding module, and its set of reference parameters, each instance of reference module being associated with a reference input signal, a reference output signal, and a collection of results of reference executions, and
• recording the different instances of reference modules of a same module in a storage system.
