## What changes were proposed in this pull request? This is the official first attempt to break huge single `tests.py` file - I did it locally before few times and gave up for some reasons. Now, currently it really makes the unittests super hard to read and difficult to check. To me, it even bothers me to to scroll down the big file. It's one single 7000 lines file! This is not only readability issue. Since one big test takes most of tests time, the tests don't run in parallel fully - although it will costs to start and stop the context. We could pick up one example and follow. Given my investigation, the current style looks closer to NumPy structure and looks easier to follow. Please see https://github.com/numpy/numpy/tree/master/numpy. Basically this PR proposes to break down `pyspark/sql/tests.py` into ...: ```bash pyspark ... ├── sql ... │ ├── tests # Includes all tests broken down from 'pyspark/sql/tests.py' │ │ │ # Each matchs to module in 'pyspark/sql'. Additionally, some logical group can │ │ │ # be added. For instance, 'test_arrow.py', 'test_datasources.py' ... │ │ ├── __init__.py │ │ ├── test_appsubmit.py │ │ ├── test_arrow.py │ │ ├── test_catalog.py │ │ ├── test_column.py │ │ ├── test_conf.py │ │ ├── test_context.py │ │ ├── test_dataframe.py │ │ ├── test_datasources.py │ │ ├── test_functions.py │ │ ├── test_group.py │ │ ├── test_pandas_udf.py │ │ ├── test_pandas_udf_grouped_agg.py │ │ ├── test_pandas_udf_grouped_map.py │ │ ├── test_pandas_udf_scalar.py │ │ ├── test_pandas_udf_window.py │ │ ├── test_readwriter.py │ │ ├── test_serde.py │ │ ├── test_session.py │ │ ├── test_streaming.py │ │ ├── test_types.py │ │ ├── test_udf.py │ │ └── test_utils.py ... ├── testing # Includes testing utils that can be used in unittests. │ ├── __init__.py │ └── sqlutils.py ... ``` ## How was this patch tested? Existing tests should cover. `cd python` and `./run-tests-with-coverage`. Manually checked they are actually being ran. Each test (not officially) can be ran via: ``` SPARK_TESTING=1 ./bin/pyspark pyspark.sql.tests.test_pandas_udf_scalar ``` Note that if you're using Mac and Python 3, you might have to `OBJC_DISABLE_INITIALIZE_FORK_SAFETY=YES`.
