-Running database-related tests
-==============================
-
-Python tests for this module include tests that cannot be run without a local
-Postgres database. You are not obliged to run those tests though:
-
-- `make test`:      will run all tests
-- `make test-nodb`: will run only tests that do not need a local DB
-- `make test-db`:   will run only tests that do need a local DB
-
-If you do want to run DB-related tests, you should:
-
-- ensure that your user is authorized to create and drop DBs, and in particular
-  DBs named "softwareheritage-test" and "softwareheritage-dev"
-
-- ensure that you have the storage testdata repository checked out in
-  ../swh-storage-testdata

+Tests
+-----
+
+This module's tests need a postgres db to run. It is recommended to run 
+those but they can be skipped:
+
+- `make test`:      will run all tests
+- `make test-nodb`: will run only tests that do not need a local DB
+- `make test-db`:   will run only tests that do need a local DB
+
+If you do want to run DB-related tests, you should ensure you have access with
+sufficient privileges to a Postgresql database.
+
+### Using your system database
+
+You need to:
+
+- ensure that your user is authorized to create and drop DBs, and in particular
+  DBs named "softwareheritage-test" and "softwareheritage-dev"
+
+- ensure that you have the storage testdata repository checked out in
+  ../swh-storage-testdata
+
+### Using pifpaf
+
+[pifpaf](https://github.com/jd/pifpaf) is a suite of fixtures and a
+command-line tool that allows to start and stop daemons for a quick throw-away
+usage.
+
+It can be used to run tests that need a Postgres database without any other
+configuration reauired nor the need to have special access to a running
+database:
+
+```bash
+
+$ pifpaf run postgresql make test-db
+[snip]
+----------------------------------------------------------------------
+Ran 12 tests in 0.903s
+
+OK
+```
+
+Note that pifpaf is not yet available as a Debian package, so you may have to
+install it in a venv.
