As long as you want! But tests will always be a multiple of the number of thumbnails/titles. For example, if you upload 3 thumbnails + the original, your test will run for a multiple of 4 days (4, 8, 12, 16, ….) to ensure every thumbnail gets an equal amount of test time. We also offer consecutive tests that will run like (AAAA,BBBB,CCCC)
