 ### Testing
 
-pydifact uses [pytest](http://pytest.org) for testing.
-Just exec `pytest` within the project folder to execute the unit tests. Make sure you installed the library properly before using `pip install -e .[dev]`.
+pydifact uses [pytest](http://pytest.org) for testing. There is a shortcut in the Makefile for your convenience:
 
-There is one test to check the performance of parsing huge files, named `test_huge_message` - you can skip that test by calling
+```bash
+make test
+```
+
+This is recommended for faster testing.

+
+There are some additional tests to check the performance of parsing huge files - you can include that tests by calling
 
 ```bash
-pytest --ignore tests/test_huge_message.py
+make test-extended
 ```
