An extensive test suite is included to test the library behavior and several examples. Library tests can be found in the [tests folder](https://github.com/huggingface/transformers/tree/master/transformers/tests) and examples tests in the [examples folder](https://github.com/huggingface/transformers/tree/master/examples).
Tests can be run using `pytest` (install pytest if needed with `pip install pytest`).
Tests can be run using `unittest` or `pytest` (install pytest if needed with `pip install pytest`).
Run all the tests from the root of the cloned repository with the commands:
```bash
python -m unittest discover -s transformers/tests -p "*test.py" -t .
python -m unittest discover -s examples -p "*test.py" -t examples
```
or
``` bash
python -m pytest -sv ./transformers/tests/
python -m pytest -sv ./examples/
```
By default, slow tests are skipped. Set the `RUN_SLOW` environment variable to `yes` to run them.

If you want to reproduce the original tokenization process of the `OpenAI GPT` paper, you will need to install `ftfy` (use version 4.4.3 if you are using Python 2) and `SpaCy`:

XNLI
~~~~~~~~~~~~~~~~~~~~~
`The Cross-Lingual NLI Corpus (XNLI) <https://www.nyu.edu/projects/bowman/xnli/>`__ is a benchmark that evaluates
the quality of cross-lingual text representations.
XNLI is crowd-sourced dataset based on `MultiNLI <http://www.nyu.edu/projects/bowman/multinli/>`: pairs of text are labeled with textual entailment
annotations for 15 different languages (including both high-ressource language such as English and low-ressource languages such as Swahili).
It was released together with the paper
`XNLI: Evaluating Cross-lingual Sentence Representations <https://arxiv.org/abs/1809.05053>`__
This library hosts the processor to load the XNLI data:
- :class:`~transformers.data.processors.utils.XnliProcessor`
