+Very small test framework for Terminology
+
+Goal
+----
+
+Avoid regressions in Terminology's code that parse and interprets escape
+codes.
+
+Dependencies
+------------
+
+- `tytest`, compiled with `-D tests=true` when running `meson`
+- a posix shell
+
+
+Tytest
+------
+
+`tytest` is a simple binary that takes escape codes in input and output an md5
+sum. This checksum is computed on the state of terminology after parsing and
+interpreting those escape codes.
+
+
+Test cases
+----------
+
+Test cases are simple shell scripts that output escape codes.
+
+How to run the tests
+--------------------
+
+A shell script called `run_tests.sh` is provided to run all the tests given in
+a test results file.
+See `run_tests.sh --help` for more information.
+
+Test results file
+-----------------
+
+When running a test through `tytest`, an md5 sum is computed. This checksum is
+stored with the name of the test in a file called `tests.results`.
+If terminology's behaviour changed, then the checksum will change. This will
+be noticed by `run_tests.sh` and will show those tests as failed.
