Reflect that this is possible:

models:
  - name: my_model
    columns:
      - name: id
        tests:
          - unique:
              name: my_cool_test

Specifically to:

• give a prettier, more recognizable name to tests with lots of arguments, which have hash-y synthetic names by default
• disambiguate multiple tests that differ only in their configs (which dbt doesn't consider a difference by default, but users might) — good callout in [Feature] Allow multiple unique tests for the same column dbt-core#4102 (comment) that we'll want a clear example/guidance on this

Also, reflect that dbt now supports an alt format for defining generic tests with lots of properties:

models:
  - name: my_model
    columns:
      - name: id
        tests:
          # og format
          - accepted_values:
              name: only_allow_abc
              values: ['a', 'b', 'c']
              config:
                severity: warn
                where: 1=1
          # alt format
          - name: only_allow_abc
            test_name: accepted_values
            values: ['a', 'b', 'c']
            config:
              severity: warn
              where: 1=1
