Each of our test templates is designed in multiple phases. For an item to be recommended, each test in each phase must pass. If an item fails a test in a phase, the tests in the next phases are not performed and the item is discarded.
Each phase is organized by complexity and time spend on the tests. For example, phase 1 is considered a screening phase. Phase 1 is fairly fast and helps us discard item that do not pass screening.
If an item fails at least one test in phase 1 we never proceed to the next tests and discard the item.
