These tests do not set statistical significance as the main role, so it doesn’t really make sense to spend a whole lot of time testing in order to find rare outcomes that your testing software did not pick up. Only run this sort of test when you are pretty certain that there’s an issue with your software, but on a regular basis, it is not worth it. Instead of wasting your money on this, use this to invest in statistical knowledge and tools, take a look at this article and you’ll see what we mean.
