Also, your request is being ran just that you don’t see it in the UI.
You can open the Postman Console and test it out.
Using the old syntax of writing tests ‘tests’ like tests['this wont work'] = true will not work with the pm.sendRequest api’s.
It’s highly advised that you use the new syntax of writing tests which is like so: pm.test('Hey this is a good way to write tests', function () {...})
and make use of the pm api’s.
