Where to puts test cases (input and output) for Util functions in Rails?

I have a method called valid_ios_deeplink_url? and I want to create some tests for it. Currently, I store the input and the correct output in a hash. Is there any better way to do this?

context 'valid_ios_deeplink_url?' do

    # Accepted iOS Deeplink URL
    test_cases = {
      'myapp://'                     => true,
      'my-app://'                    => true,
      'my.app://'                    => true,
      'myapp://invite'               => true,
      'myapp://?a=42'                => true,
      'myapp://?a=42&b=42'           => true,
      'myapp://invite-friend'        => true,
      'myapp://invite_friend'        => true,
      'myapp://invite?a=42'          => true,
      'myapp://invite?a_1=42'        => true,
      'myapp://invite/friend?a=42'   => true,
      'myapp://invite/friend?a_1=42' => true,
      "myapp"                        => false,
      "myapp:"                       => false,
      "myapp:/"                      => false,
      "myapp://a=42"                 => false,
      "my_app://"                    => false,
      "2myapp://"                    => false,
      ".myapp://"                    => false,
      "+myapp://"                    => false,
      "-myapp://"                    => false,    
    }

    test_cases.each do |url, result|
      it "'#{url}'" do
        is_valid = UrlUtil::valid_ios_deeplink_url?(url)
        expect(is_valid).to be result
      end
    end

  end
