I’m interested - what would you class as a “silly test idea”? For me, it all depends on context and goals. A test that might seem silly to one person might actually be totally valid and relevant to another, in a given context.
Put extremely simply, a test to me is an experiment; a way of conducting research. I see a lot of cross-over with, and ideas we can draw from, the area of science. I don’t think we need to get super specific about what a test is, because the possibilities are so broad. I think that’s a good thing, and one of the fun things about testing.
