What is Mocking?
Creating fake versions of external services or components during testing so tests run reliably and quickly.
Why It Matters
Mocking lets you test your code without depending on real databases, APIs, or other services that might be slow or unavailable.
Real-World Example
Using a mock payment API in tests so you can verify your checkout logic without making real charges.
“Understanding terms like Mocking matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”
