 ### Launching the tests
 
-We have unit tests with `py.test`, they'd be typically run in a virtualenv:
+We have unit and integration tests with `pytest`, they'd be typically
+run in a virtualenv:
 
 ```
 python 3 -m venv venv
-venv/bin/pip install -r install-requirements.txt -r test-requirements.txt
-venv/bin/pytest
+source venv/bin/activate
+./run-all-tests
 ```
 
-Note: relying on virtualenv activation to run the tests simply as `pytest` has
-been playing tricks with us, but the direct form above worked in all cases
+We have a 100% coverage policy, that is enforced by `run-all-tests` and
+therefore by the continuous integration.
+
+This full run takes about 20 seconds in our continuous integration, and
+usually less than that on developer workstations.
