dbt unit test where source table has the same name as the model

Help
1

I’m trying to create a unit test (Running with dbt=1.8.3, Registered adapter: trino=1.8.1) for incremental load based on the documentation: Unit tests | dbt Developer Hub

The issue I’m facing is that my input source (from the sources.yaml) is a table that has the same name as the model. In the compiled sql it only creates one cte for the source and the {{ this }}) input and the execution fails. Do you have any suggestions?

table_name.sql

SELECT *
    FROM {{ source('test', 'table_name') }} table_name

    {% if is_incremental() %}
    WHERE table_name.updated_at >= (SELECT updated_at FROM {{ this }})
    {% endif %}

unit_test.yaml

unit_tests:
    - name: table_name_incremental_mode
      model: table_name
      overrides:
          macros:
              # unit test this model in "incremental" mode
              is_incremental: true
      given:
          -   input: this
              rows:
                  - { event_id: 1, event_time: 2020-01-01}
          -   input: source('test', 'table_name')
              rows:
                  - { event_id: 1, event_time: 2020-01-01}
                  - { event_id: 2, event_time: 2020-01-02}
