Regression tests
================

Regression test configuration is controlled entirely by ``TEST_NS`` or
``TEST_S`` or single test suite configuration. The group test
configurations and single test suite configurations are listed below, all of
them are disabled by default.

Individual test suites can be enabled when their dependencies like partitions or
other specific configurations are set. On the one hand, some test suites depend
on other test suites. On the other hand, some test suites conflict with
other test suites. Test configurations and dependencies will be
checked in ``${TFM_TEST_REPO_PATH}/test/config/check_config.cmake``.

If regression testing is enabled by ``TEST_NS`` or ``TEST_S``, individual
test suites will be enabled or disabled as appropriate for the TF-M
configuration (i.e. all enabled secure partitions will be tested).

Some cryptographic tests can be enabled and disabled. This is done to prevent
false failures from being reported when a smaller Mbed Crypto config is being
used which does not support all features.

PSA tests
=========

PSA tests are configured by using the ``TEST_PSA_API`` cmake variable. The
variable should be set to the name of the test suite that is desired. It is
_not_ supported to set both ``TEST_PSA_API`` and ``TEST_S`` or ``TEST_NS``.

The Functional API tests are:
 - ``CRYPTO``
 - ``INITIAL_ATTESTATION``
 - ``STORAGE`` (INTERNAL_TRUSTED_STORAGE and PROTECTED_STORAGE)
 - ``INTERNAL_TRUSTED_STORAGE``
 - ``PROTECTED_STORAGE``

The Firmware Framework test suites are:
 - ``IPC``

Note that these map directly to the ``SUITE`` cmake variable used in the
psa-arch-tests documentation.
