Make source freshness test descriptions configurable

[waligob]

Is your feature request related to a problem? Please describe.
It appears that the test description for source freshness tests is a hard-coded string.

Describe the solution you'd like
It would be helpful if this could be made configurable via a property under the meta block.

Describe alternatives you've considered
As a workaround, we're appending metadata to sources[].tables[].description, but that requires navigating from the test results to Elementary's lineage graph, and then selecting "..." > "Node info" in order to view that metadata

Additional context

Would you be willing to contribute this feature?
Yes!

This issue is duplicated from elementary-data/dbt-data-reliability#807

Hey @waligob ! 🙂
This string is the default in case there's no customized description.
Try adding this:

  - elementary.freshness_anomalies:
          meta:
              description: "Your own test description"

Let me know if this helps.

@NoyaOffer Given the following freshness test configuration, where would your snippet go if I wanted to override the default description?

sources:
  - name: auth0
    loader: Stitch
    tables:
      - name: auth0_export
        description: >
          This table contains an export of our auth0 database.
          auth0 is used for user authentication and is our source for registered users
        loaded_at_field: _sdc_batched_at
        freshness:
          error_after:
            count: 28
            period: hour

This still reproduces on the current implementation.

The source freshness description appears to still be hard-coded here:
https://github.com/elementary-data/elementary/blob/v0.23.1/dbt-data-reliability/macros/edr/dbt_artifacts/upload_dbt_sources.sql#L89-L90

Because of that, it does not seem that description can currently be overridden for source freshness alerts in the same way it can for regular dbt tests.

Also, based on the current behavior, the suggestion in the previous comment to use:

- elementary.freshness_anomalies:
    meta:
      description: "Your own test description"

does not seem to apply to dbt source freshness alerts. That may work for Elementary freshness anomaly tests, but not for dbt source freshness results.

So unless I am missing another supported configuration path, this looks like an unresolved product gap rather than a user configuration issue.
Could this issue be reopened?
