Testing PySpark

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

build/mvn -DskipTests clean package

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

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, run tests for a module, or individual tests.

Running Individual PySpark Tests

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

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

Please refer to Testing PySpark 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 for more details.
