"""Describe the test coverage of PSA functions in terms of return statuses.
|
|
|
|
1. Build Mbed Crypto with -DRECORD_PSA_STATUS_COVERAGE_LOG
|
|
2. Run psa_collect_statuses.py
|
|
|
|
The output is a series of line of the form "psa_foo PSA_ERROR_XXX". Each
|
|
function/status combination appears only once.
|
|
|
|
This script must be run from the top of an Mbed Crypto source tree.
|
|
The build command is "make -DRECORD_PSA_STATUS_COVERAGE_LOG", which is
|
|
only supported with make (as opposed to CMake or other build methods).
