Testing PySpark
===============

In order to run PySpark tests, you should build Spark itself first via Maven or SBT. For example,

.. code-block:: bash

    build/mvn -DskipTests clean package

After that, the PySpark test cases can be run via using ``python/run-tests``. For example,

.. code-block:: bash

    python/run-tests --python-executable=python3

Note that you may set ``OBJC_DISABLE_INITIALIZE_FORK_SAFETY`` environment variable to ``YES`` if you are running tests on Mac OS.

Please see the guidance on how to `build Spark <https://github.com/apache/spark#building-spark>`_,
`run tests for a module, or individual tests <https://spark.apache.org/developer-tools.html>`_.


Running Individual PySpark Tests
--------------------------------

You can run a specific test via using ``python/run-tests``, for example, as below:

.. code-block:: bash

    python/run-tests --testnames pyspark.sql.tests.test_arrow

Please refer to `Testing PySpark <https://spark.apache.org/developer-tools.html>`_ for more details.


Running tests using GitHub Actions
----------------------------------

You can run the full PySpark tests by using GitHub Actions in your own forked GitHub
repository with a few clicks. Please refer to
`Running tests in your forked repository using GitHub Actions <https://spark.apache.org/developer-tools.html>`_ for more details.
