Amanda Liu created SPARK-44042: ---------------------------------- Summary: SPIP: PySpark Test Framework Key: SPARK-44042 URL: https://issues.apache.org/jira/browse/SPARK-44042 Project: Spark Issue Type: New Feature Components: PySpark Affects Versions: 3.5.0 Reporter: Amanda Liu
Currently, there's no official PySpark test framework, but only various open-source repos and blog posts. Many of these open-source resources are very popular, which demonstrates user-demand for PySpark testing capabilities. [spark-testing-base|https://github.com/holdenk/spark-testing-base] has 1.4k stars, and [chispa|https://github.com/MrPowers/chispa] has 532k downloads/month. However, it can be confusing for users to piece together disparate resources to write their own PySpark tests (see [The Elephant in the Room: How to Write PySpark Tests|https://towardsdatascience.com/the-elephant-in-the-room-how-to-write-pyspark-unit-tests-a5073acabc34]). We can streamline and simplify the testing process by incorporating test features, such as a PySpark Test Base class (which allows tests to share Spark sessions) and test util functions (for example, asserting dataframe and schema equality).
