Description

Fixed flaky test testDateHandling in TimestampsParquetReaderTest.java with JSONAssert

Location: extensions-core/parquet-extensions
Filename: TimestampsParquetReaderTest.java
Test: testDateHandling

1. Test Overview:
   In the TimestampsParquetReaderTest.testDateHandling test, we assess how timestamps are handled in Parquet files, focusing on date values stored as strings and date objects. The test checks the consistency of timestamp conversion and verifies that the JSON representations of these timestamps match the expected values.

2. Reason of flakiness:
   However, a potential problem arises because the data reading methods used createReader() does not always retrieve data in a consistent order, possibly introducing randomness. This can lead to different JSON representations of the same data during test runs.

3. Changes:

• Imported JSONAssert and JSONException packages, and changed from using standard assertion method Assert to using JSONAssert when comparing two results sampledAsString and sampledAsDate with expectedJson.

• Add org.json and org.skyscreamer dependencies to pom.xml file in /parquet-extensions.

  To address this issue, the PR proposes changing the comparison approach from a standard assertion method Assert to using JSONAssert.
  JSONAssert method allows for a comparison of data equality without considering the order in which the data is retrieved. This change ensures more reliable and consistent test results across different runs, regardless of variations in data retrieval order.

Release note

Fixed: TimestampsParquetReaderTest.testDateHandling test no longer fail when running with the NonDex tool.

LGTM, one suggestion is to provide links to documentation for data reading methods used may not always retrieve data in a consistent order

Looks good!. Please check for code style. There can be checkstyle errors.

Is the JSONException type necessary here? Developers might be reluctant to add a new dependency for printing an error message in a test.

[219sansim]

See if you can remove dependencies that you included in the code.
