But

This macro command allows you to test the non-regression of files produced by the Code_Aster commands, mainly IMPR_RESU, but it can be used on any text file.

To test a file, we extract the list of real numbers and integers present in the file, the cardinal of this list, and all the remaining text (once the numbers have been extracted).

For numbers, we check the non-regression of the sum, the absolute sum or the min/max of the values to within precision.

To test the text in the file, we use the Python module md5, which provides a "signature" of the text (called md5sum).

Returns OK if the file is identical to the file that was used as a reference, NOOK otherwise.

This command is used mainly by test cases to validate the non-regression of the results.
