Let's cut the fluff. Here is exactly what you need to know about Mocking & Spies to survive in a real production environment.
1Concept 1: Advanced Mocking & Spies Architecture
Look, if you've ever dealt with Mocking & Spies in production, you know exactly what the problem is. Most juniors implement this completely wrong, leading to massive performance bottlenecks. This isn't just academic theory—understanding the *why* behind this architectural decision is what separates beginners from senior Testing Masterclass engineers. When you deploy to a global edge network, this is the mechanic that prevents catastrophic memory leaks.
