'''Runs tests for the default suppression specifications of libabigail.
|
|
|
|
This program tries to exercise the reading of default suppression
|
|
files by the abidiff and abipkgdiff programs.
|
|
|
|
It reads a set of input files to ABI-compare, along with a
|
|
suppressions specification and a reference output. The test points
|
|
the environment variables LIBABIGAIL_DEFAULT_SYSTEM_SUPPRESSION_FILE
|
|
and LIBABIGAIL_USER_SYSTEM_SUPPRESSION_FILE environment variables at
|
|
the suppression specification and runs abidiff to compare the two
|
|
input binary files. The result of the comparison should be equal to
|
|
the reference output, meaning that the suppression specification was
|
|
taken into account.
