def test_cross_engine_pa_fp(df_cross_compat, pa, fp):Problem description
Building the development environment of pandas from latest master source, and then running the pytest suite on a fresh install with no changes, leads to test_cross_engine_pa_fp test in test_parquet.py, which is expected to fail, passing. This could be due to the fact that either Python 3.7 or OS X 10.14 now supports what this test is testing for, cross-compat with differing reading/writing engines. Since this is the case, loosening the strictness of this test, per @TomAugspurger suggestion, should fix this. I can open up a pr for this.
Expected Output
Unit tests should not report failures
Output of pd.show_versions()
