Test Everything Twice (TET)

A playful backronym coined live in the TWiQ chat as a testing-world companion to the DRY/WET family of terms, standing for "Test Everything Twice." as a counterpart to WET (Write Everything Twice), it captures the idea of deliberate, thorough verification rather than assuming a single test pass is sufficient. Like WET and DRY, it works best as a conversational shorthand for a mindset rather than a strict rule.
