Create a modern and clean icon symbolizing a Quality Assurance (QA) environment. The design should feature a magnifying glass hovering over a checklist or a bug symbol, indicating testing and debugging. Use a light, neutral background with contrasting colors like blue, green, and yellow to highlight the elements. The magnifying glass should have a slight 3D effect, and the checklist or bug should be minimalistic but clearly visible. The icon should communicate precision, attention to detail, and reliability, with a polished, professional look.
