Integration Testing - System Design

Added: 2026-05-17

[00:00:00]If you don't know this, you suck at system design. We've tested that individually they work on their own. Now we want to see how they work together.

[00:00:06]We'd write code that connects to the database, then perform a real action, and then verify we get what we expect.

[00:00:13]So while unit testing will focus on a single function or class, integration testing is all about the interaction of services. Unit testing is just for logic, whereas integration testing is for the handshake. Software testing's not the most interesting, but it is pretty important. So follow me for a bit more.
