 Some variables only compute at runtime, such as a variable from an HTTP request or a JavaScript step. For example, assume you have a `Type text` step featuring `{{ <YOUR_VARIABLE_NAME> }}`. At test execution, `{{ <YOUR_VARIABLE_NAME> }}` is systematically replaced by your variable's associated value. To record a step using one of these variables, record a step with the actual variable value, and replace the actual value with `{{ <YOUR_VARIABLE_NAME> }}` in the step's definition before saving your test.
