| Jimmy Brisson | 6fcd961 | 2020-04-02 15:19:20 -0500 | [diff] [blame] | 4 | This page provides an overview of the current TF-A Tests feature set. The |
| 5 | :ref:`Change Log & Release Notes` document provides details of changes made |
| 6 | since the last release. |

| Jimmy Brisson | 6fcd961 | 2020-04-02 15:19:20 -0500 | [diff] [blame] | 8 | Current Features |
| 9 | ---------------- |
| 10 | |
| 11 | The following TF-A features are currently tested to some extent (this list is |
| 12 | not exhaustive): |
| 13 | |
| 14 | - `SMC Calling Convention`_ |
| 15 | - `Power State Coordination Interface (PSCI)`_ |
| 16 | - `Software Delegated Exception Interface (SDEI)`_ |
| 17 | - `Performance Measurement Framework (PMF)`_ |
| 18 | - Communication and interaction with the `Test Secure Payload (TSP)`_ |
| 19 | - `Firmware update`_ (or recovery mode) |
| Jimmy Brisson | 4844dc9 | 2020-04-02 15:19:34 -0500 | [diff] [blame^] | 20 | - `EL3 payload boot flow`_ |
| 21 | - Secure partition support |
| Jimmy Brisson | 6fcd961 | 2020-04-02 15:19:20 -0500 | [diff] [blame] | 22 | |
| 23 | These tests are not a compliance test suite for the Arm interface standards used |
| 24 | in TF-A (such as PSCI). |
| 25 | |
| 26 | They do not cover 100% of the TF-A code. The fact that all tests pass does not |
| 27 | mean that TF-A is free of bugs. |
| 28 | |
| 29 | They are not reference code. They should not be considered as the official way |
| 30 | to test hardware/firmware features. Instead, they are provided as example code |
| 31 | to experiment with and improve on. |
| 32 | |
| 33 | Still to come |
| 34 | ------------- |
| 35 | |
| 36 | - Additional tests |
| 37 | - Support for new platforms |
| 38 | - Design improvements |
| 39 | - Stability improvements |
| 40 | - Enhancements to the test framework to make it easier to implement tests |
| 41 | - Fixes for known issues (detailed in :ref:`Change Log & Release Notes`) |
