What is Day-in-the-Life Testing (DITL)?
Testing that simulates a realistic business day or period with users performing their normal sequence of tasks.
DITL validates roles, workload, timing, and handoffs in a production-like rhythm. It often includes month-end close simulation. It is usually run late in UAT or as a business readiness exercise.
