    - name: Create a Linode User
      linode.cloud.user:
        username: 'testing-user-1'
        email: 'testing-user-1@linode.com'
        state: present
      register: create_user_1

    - name: Create another Linode User
      linode.cloud.user:
        username: 'testing-user-2'
        email: 'testing-user-2@linode.com'
        state: present
      register: create_user_2

    - name: List users with no filter
      linode.cloud.user_list:
      register: no_filter

    - name: List users with a filter on username
      linode.cloud.user_list:
        filters:
          - name: username
            values: testing-user-1
      register: filter_username

    - name: Delete a Linode User
      linode.cloud.user:
        username: '{{ create_user_1.user.username }}'
        state: absent

    - name: Delete a Linode User
      linode.cloud.user:
        username: '{{ create_user_2.user.username }}'
        state: absent

2. Ensure that the user list is returned and filtered properly.
