You have to call it a test before you begin.
Plenty of failed ideas are reclassified as tests when they don’t pan out.
And if it is a test, define success and failure first.
How many people need to do [x] for the test to be considered a success?
There should be no confusion about whether the test was a success or not.
And be clear about what you will do if the test succeeds or fails (again, before you begin).
The point of a test is to take a hunch and remove any subjective bias for the benefit of the community.
You should test your hunches in your community, just set some standards before you start.
