    • If you don't see the change in the Env tab, close and re-open the tab to refresh it.

Set Env with Scope

The default location will be Active Environment when you use {{variable}}. You can use a scope to control which environment variable to set the value explicitly.

Set Env Variable Scope
  • To set a variable in the local environment use {{variable, local}}.
  • To set a variable in the global environment use {{variable, global}}.

tc.setVar(varName, value, "local");
// To save to global environment
