EARL Test Reports
4747
=================
4848

49-
EARL test reports can be generated using the EARL reporter plugin from ``earl.py``.
50-
51-
When this plugin is enabled it will create an ``earl:Assertion`` for every test that has a ``rdf_test_uri`` parameter which can be either a string or an ``URIRef``.
52-
53-
To enable the EARL reporter plugin an output file path must be supplied to pytest with ``--earl-output-file``. The report will be written to this location in turtle format.

EARL test reports are generated using the EARL reporter plugin from ``test/utils/earl.py``.
50+
51+
This plugin is enabled by default and writes test reports to ``test_reports/*-latest.ttl`` by default.
52+
53+
For EARL reporter plugin options see the output of ``pytest --help``.
