PySpark DataFrame Testing Utility

pyspark-test is a Python library designed to simplify unit testing for PySpark DataFrames. It provides a function, `assert_pyspark_df_equal`, inspired by the pandas testing module, which allows users to compare two Spark DataFrames and identify any differences. The library is currently at version 0.2.0 and has a stable, albeit infrequent, release cadence, focusing on its core DataFrame comparison functionality.
