how to add multiple variable in dbt test yml file?

I’m having two variable that i want to put in my dbt test yml file

i want to include two list of countries values in the ‘accepted value’ test

I have tried this but does not work

code

models:
  - name: my_table_that_i_want_to_test
    columns:
      - name: my_column
        tests:
        - accepted_values:
            values: “{{ var(‘country_list1’) + var(‘country_list2’) }}”

thank you in advance!

What does this test look like when compiled, if it gets that far? That might give you some insight into what’s happening.
