-# Compiling the library
+# Unit tests for core COCO framework
 
-If none of the compiled cmocka libraries works on your computer you need to compile it by yourself. 
+## Conventions
 
-You can follow this instructions http://zhuyong.me/blog/2014/03/19/c-code-unit-testing-using-cmocka/
-but you should download the latest version of cmocka library files from: https://cmocka.org/files/1.0/
-
-Then add the compiled library to the 'lib' folder (create a new subfolder in `lib` and copy the library
-to it) and update the `build_c_unit_tests()` in the `do.py` so that the correct library is copied to the
-unit-test folder.

-# Unit-testing instructions
-
-We use the following naming convention for unit test files: you add a prefix `test_` to the name of the
-file that you are testing (e.g. `coco_utilities.c` -> `test_coco_utilities.c`). 
+We use the following naming convention for unit test files: you add a prefix
+`test_` to the name of the file that you are testing (e.g. `coco_utilities.c`
+-> `test_coco_utilities.c`). 
 
 All test files should be included in this folder. Each test file should contain a central function, in
 which are the tests from the file are called (e.g. `test_all_coco_utilities` in `test_coco_utilities.c`). 
 A specific test should be testing a small part of the code. See `test_coco_utilities.c` for some test
 examples.
 
-The starting file for unit testing is `unit_test.c`, from which all the other test files are called.
-When you add a new test file, you need to include it in `unit_test.c` and add its central function to
-the function `run_all_tests`.
-
-In the root folder you can find the `do.py` script. You should call `python do.py test-c-unit` to run
-the tests.
