TestCafe : How can I make TestCafe to run some application code only once before all the fixtures

In my application, I want to set up some test data from the UI before running any Fixture. I want to do this set up only once and don't want to do this before each fixture. Can someone please help me on how to do this ?

I tried to use approach mentioned on below thread but I cannot use test controller - t inside before.
