Terraform, conditionally execute some lines of code in template file

In terraform, is there any way to conditionally execute some lines of code in template file? For example:

I have a test.sh.tpl file defined as below called from main.tf:

#!/bin/bash
echo ${test_key} > /opt/test_key.properties

In the above value to "test_key" is assigned from variable

Now I want to execute the above code only if ${test_key} value is not empty. I tried this, but not working even the value exists

{ if ${test_key} != "" }

echo ${test_key} > /opt/test_key.properties

{ endif }

probably because you are missing % before you brackets.

%{ if test_key != "" }

echo ${test_key} > /opt/test_key.properties

%{ endif }

https://www.terraform.io/docs/language/expressions/strings.html

NOTE: The test_key is not in ${} since we are already evaluating expressions as code.
