-Running Syrupy Tests
-======================
-The tests module is currently being restructured to use `Syrupy <https://github.com/tophat/syrupy>`_. 
-These tests generate individual HDF(for Pandas) and ``.npy`` or ``.npz`` (for NumPy) files(or snapshots) for each test case.
-For other objects, the plugin serialises them and saves them as ``.ambr`` files. There is a custom extension in the 
-main local `conftest <https://github.com/tardis-sn/tardis/blob/master/tardis/conftest.py>`_ file to get this to work.
-The plugin currently only supports ``assert_allclose`` for NumPy and ``assert_series_equal`` and ``assert_frame_equal`` for 
-Pandas. Snapshots can be generated by using the same ``--generate-reference`` flag and are compared automatically.
-You however need to provide the location to your snapshot directory using the ``--tardis-snapshot-data`` flag.
-The snapshots are also saved in `tardis-sn/tardis-regressions <https://github.com/tardis-sn/tardis-regressions>`_.
