-# Mbed TLS test framework
-
-This document is an overview of the Mbed TLS test framework and test tools.
-
-This document is incomplete. You can help by expanding it.
-
-## Unit tests
-
-See <https://tls.mbed.org/kb/development/test_suites>
-
-### Unit test descriptions
-
-Each test case has a description which succinctly describes for a human audience what the test does. The first non-comment line of each paragraph in a `.data` file is the test description. The following rules and guidelines apply:
-
-* Test descriptions may not contain semicolons, line breaks and other control characters, or non-ASCII characters. <br>
-  Rationale: keep the tools that process test descriptions (`generate_test_code.py`, [outcome file](#outcome-file) tools) simple.
-* Test descriptions must be unique within a `.data` file. If you can't think of a better description, the convention is to append `#1`, `#2`, etc. <br>
-  Rationale: make it easy to relate a failure log to the test data. Avoid confusion between cases in the [outcome file](#outcome-file).
-* Test descriptions should be a maximum of **66 characters**. <br>
-  Rationale: 66 characters is what our various tools assume (leaving room for 14 more characters on an 80-column line). Longer descriptions may be truncated or may break a visual alignment. <br>
-  We have a lot of test cases with longer descriptions, but they should be avoided. At least please make sure that the first 66 characters describe the test uniquely.
-* Make the description descriptive. “foo: x=2, y=4” is more descriptive than “foo #2”. “foo: 0<x<y, both even” is even better if these inequalities and parities are why this particular test data was chosen.
-* Avoid changing the description of an existing test case without a good reason. This breaks the tracking of failures across CI runs, since this tracking is based on the descriptions.
-
-`tests/scripts/check_test_cases.py` enforces some rules and warns if some guidelines are violated.
-
-## TLS tests
-
-### SSL extension tests
-
-#### SSL test case descriptions
-
-Each test case in `ssl-opt.sh` has a description which succinctly describes for a human audience what the test does. The test description is the first parameter to `run_tests`.
-
-The same rules and guidelines apply as for [unit test descriptions](#unit-test-descriptions). In addition, the description must be written on the same line as `run_test`, in double quotes, for the sake of `check_test_cases.py`.
-
-## Running tests
-
-### Outcome file
-
-#### Generating an outcome file
-
-Unit tests and `ssl-opt.sh` record the outcome of each test case in a **test outcome file**. This feature is enabled if the environment variable `MBEDTLS_TEST_OUTCOME_FILE` is set. Set it to the path of the desired file.
-
-If you run `all.sh --outcome-file test-outcome.csv`, this collects the outcome of all the test cases in `test-outcome.csv`.
-
-#### Outcome file format
-
-The outcome file is in a CSV format using `;` (semicolon) as the delimiter and no quoting. This means that fields may not contain newlines or semicolons. There is no title line.
-
-The outcome file has 6 fields:
-
-* **Platform**: a description of the platform, e.g. `Linux-x86_64` or `Linux-x86_64-gcc7-msan`.
-* **Configuration**: a unique description of the configuration (`config.h`).
-* **Test suite**: `test_suite_xxx` or `ssl-opt`.
-* **Test case**: the description of the test case.
-* **Result**: one of `PASS`, `SKIP` or `FAIL`.
-* **Cause**: more information explaining the result.
