I am trying to provide documentation for a dbt tests.
I have created a test validating the sum of 2 numbers (of course, this is just an example).

{% test test_sum(summand_a, summand_b, total) %}
SELECT 
    {{summand_a}} + {{summand_b}} AS result 
WHERE result <> {{total}}
{% endtest %}

I have created a test.yml file next to the test with the following content:

version: 2

tests:
  - name: test_sum
    description: 'This test validates the sum of 2 numbers'

When generating dbt docs via dbt docs generate the test does not show any documentation.

I expect the test do be documented when serving the docs via dbt docs serve
