Errors when trying to run Flask's testsuite

I followed how to contribute to Flask tutorial.

When I run pytest tests/*.py, the tests pass but when I run simply pytest (as asked on the reference above), I get this error message:

Now that Flask 1.0 is out, pytest alone will only run the tests in the tests directory. After installing the examples, use pytest tests examples to test both.

pip install -e examples/tutorial
pip install -e examples/javascript
pytest tests examples

The contributing docs are were out of date, you need to run pytest tests. If you want to test the examples (which is what's failing now) you need to install them like tox does.

pip install -e examples/flaskr
pip install -e examples/minitwit
pip install -e examples/patterns/largerapp
pytest

Alternatively, run tox -e py to run the entire test suite, or tox to run the suite on all supported Python versions.
