A test that checks multiple parts of a system working together.
Integration tests catch bugs that unit tests miss, such as API-to-database behavior or UI-to-route wiring. They are slower but closer to real use.
Plainly
Think of Integration Test as a simple recipe for doing the work better. A test that checks multiple parts of a system working together.
In practice
Use it when you need a repeatable method instead of guessing from vibes. In practice, define the owner, input, output, and failure mode before you rely on it.
