> It takes 15 seconds in debug mode (probably more with ASAN / UBSAN /etc.) to
> run 2 tests that simply iterated through a generated in-memory dataset:
> {code}
> $ ./build-test/debug/arrow-dataset-file-parquet-test
> Running main() from
> /home/conda/feedstock_root/build_artifacts/gtest_1551008230529/work/googletest/src/gtest_main.cc
> [==========] Running 2 tests from 1 test case.
> [----------] Global test environment set-up.
> [----------] 2 tests from TestParquetFileFormat
> [ RUN ] TestParquetFileFormat.ScanRecordBatchReader
> [ OK ] TestParquetFileFormat.ScanRecordBatchReader (7338 ms)
> [ RUN ] TestParquetFileFormat.Inspect
> [ OK ] TestParquetFileFormat.Inspect (6222 ms)
> [----------] 2 tests from TestParquetFileFormat (13560 ms total)
> [----------] Global test environment tear-down
> [==========] 2 tests from 1 test case ran. (13560 ms total)
> [ PASSED ] 2 tests.
> {code}
> Unless it is stressing something in particular, the number of repetitions or
> the batch size can probably be reduced dramatically.
