Test Suites ###########
TF-M includes two sets of test suites:
These test suites can be run from Zephyr via an appropriate sample application in the samples/tfm_integration folder.
TF-M Regression Tests
The regression test suite can be run via the :ref:tfm_regression_test sample.
This sample tests various services and communication mechanisms across the NS/S boundary via the PSA APIs. They provide a useful sanity check for proper integration between the NS RTOS (Zephyr in this case) and the secure application (TF-M).
PSA Arch Tests
The PSA Arch Test suite, available via :ref:tfm_psa_test, contains a number of
test suites that can be used to validate that PSA API specifications are
being followed by the secure application, TF-M being an implementation of
the Platform Security Architecture (PSA).
Only one of these suites can be run at a time, with the available test suites
described via CONFIG_TFM_PSA_TEST_* KConfig flags:
Purpose
The output of these test suites is required to obtain PSA Certification for your specific board, RTOS (Zephyr here), and PSA implementation (TF-M in this case).
They also provide a useful test case to validate any PRs that make meaningful changes to TF-M, such as enabling a new TF-M board target, or making changes to the core TF-M module(s). They should generally be run as a coherence check before publishing a new PR for new board support, etc.
