Prompt tests fail quietly when the \u201csame\u201d prompt is not actually run under the same conditions. A clean session prompt testing workflow reduces hidden variables like chat history, mode flags, and personalization so reruns are comparable and drift is explainable.<\/p>\n
A clean session is a test run where the model has no prior conversation context, and your environment is controlled enough that the output differences are likely caused by the prompt (or an intentional config change). It does not mean the answer will be identical every time.<\/p>\n
Think of it as QA hygiene for prompts: you\u2019re trying to isolate the input-output relationship, not chase perfect determinism.<\/p>\n

Most teams start with \u201cnew chat, paste prompt, judge output.\u201d Then results swing on the second run and nobody can tell what changed.<\/p>\n
