NON-REGRESSION METHOD OF A TOOL FOR DESIGNING A MONITORING SYSTEM OF AN AIRCRAFT ENGINE

摘要

The invention relates to a system of non-regression tests of a designing tool including modules (13) used to build a monitoring device (11) of an aircraft engine (7), said system of tests including:
processing means (9) configured to automatically create an experience base (9e) by instrumenting behaviour tests upon executing the modules, said experience base including reference input signals (SIN—ref), sets of reference parameters, reference output signals (SOUT—ref), and collections of results of reference executions relating to said modules,processing means (9) configured to start again said behaviour tests on said modules (13) depending on the corresponding reference input signals and the corresponding sets of reference parameters thus generating test output signals (SOUT—test) and collections of results of test executions, andprocessing means (9) configured to compare said test output signals with the corresponding reference output signals and said collections of results of test execution with said corresponding collections of results of reference executions in order to test the non-regression of the designing tool.

1. A method of non-regression tests of a tool for designing a monitoring device (11) of an aircraft engine (7), said designing tool including modules (13) 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, characterized in that said method includes the following steps of:
automatically creating an experience base (9e) by instrumenting behaviour tests upon executing the modules (13), said experience base including reference input signals (SIN—ref), sets of reference parameters (param_ref), reference output signals (SOUT—ref), and collections of results of reference executions relating to said modules, starting again said behaviour tests on said modules depending on the corresponding reference input signals and the corresponding sets of reference parameters thus generating test output signals (SOUT—test) and collections of results of test executions, and comparing 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.
