+### Recommended `pytest` options
+
+pytest provides a [lot of command-line options](https://docs.pytest.org/en/8.0.x/reference/reference.html#command-line-flags)
+to fine-tune how the test suite is executed (test selection, reporting, ...).
+Some recommended options to use in practice:
+
+- `-vv`: increase verbosity while running the test,
+  e.g. to have a better idea of the progress of slow tests.
+- `--tb=no`: avoid output of full stack traces,
+  which give little to no added value for some test modules.
