 ## Adding tests
 
-spaCy uses [pytest](http://doc.pytest.org/) framework for testing. For more info on this, see the [pytest documentation](http://docs.pytest.org/en/latest/contents.html). Tests for spaCy modules and classes live in their own directories of the same name. For example, tests for the `Tokenizer` can be found in [`spacy/tests/tokenizer`](tests/tokenizer). To be interpreted and run, all test files and test functions need to be prefixed with `test_`.
