عرض عملي: اختبار ممتد يكشف تسرّبًا بطيئًا

خطوة بخطوة

1. Run a 20-minute load test of checkout: green.
2. Start the soak at moderate load and open heap and GC dashboards.
3. Planned mistake: judge success from the first 20 minutes; at hour one old-generation memory keeps climbing and GC pauses grow.
4. Take a heap dump or profile; find the growing cache or unclosed resource.
5. Fix it, rerun the soak, and show flat memory.
6. Write the finding with graphs and the evidence chain.
