[BUG] 30_max_analyzed_offset failing

[dblock]

What is the bug?

FAILED test_opensearchpy/test_server/test_rest_api_spec.py::test_rest_api_spec[OpenSearch-main/rest-api-spec/src/main/resources/rest-api-spec/test/search/highlight/30_max_analyzed_offset[5]]

How can one reproduce the bug?

Latest builds are failing in this REST spec.

• The failing test link is here.

• This failure is related to this issue.

• The fix is present in opensearch 2.x, but it is unreleased. Ideally, the fix may be included in version 2.13.0 when it is released.

• I believe the skip version in this test should be set to " - 2.12.99". @Xtansia, what do you think? Did I miss anything?

Additional info:

• I debugged the opensearch-net client to check if this test is executed and noticed that it is skipped for all currently released opensearch versions. It is only running for the unreleased version, where it is working fine. @Xtansia, I have one more question: How is the opensearch-net client correctly interpreting the skip version as " - 2.12.99" even though it is currently specified as " - 2.1.99"

• Regarding opensearch-rs, similar to opensearch-net yaml test is skipped for released opensearch versions and is running fine for unreleased versions.

Got it @Xtansia! In opensearch-net's YAML test runner, tests against each opensearch version are taken from the corresponding opensearch version, such as 2.x branch when tests are run against 2.x.

On the other hand, opensearch-py uses only yaml tests from the main branch to test all opensearch versions.

Thomas, what do you think is the correct way to test? I'm inclined towards testing all opensearch versions against the opensearch main branch yaml tests. This should be the place where we'll have all the tests correctly, including skip tests that determine whether the test should be run on a particular branch or not.

If I understand correctly OpenSearch/main and 2.x are eventually consistent and should be identical? So it shouldn't matter where we take them from. However, I think it's best if we standardized on one way of doing it.

Another thought. If OpenSearch 3.x (main) removes an API, would it be deleted from main? In that case we want to take tests from 2.x.

Listing other failing tests against the unreleased OpenSearch main branch. Working on fixing them.

@dblock @saimedhi For both .NET & Rust this behaviour of picking the tests from the matching branch/revision of the OS cluster was inherited in the fork from Elastic. Even if main is eventually consistent, it seems evident that taking the tests intended for a given version will be more reliable.

Fixed in #696.
