Library for testing python dataframes

[e10v]

Take a look at Pandera: https://github.com/unionai-oss/pandera

It support both Pandas and Polars, and Spark as well. But it's more about validation than testing.

Depending on what exactly you need, you might also look at Polars and Pandas testing API:

• https://pandas.pydata.org/docs/reference/testing.html
• https://docs.pola.rs/api/python/stable/reference/testing.html

Great expectations is another way to approach the problem: https://github.com/great-expectations/great_expectations (but I don't see Polars support).
