Integration test
A test that verifies multiple components work correctly together.
Example
An integration test confirms that the checkout service can save an order to the database.
Why it matters
It finds problems that are invisible when each part is checked alone.
You'll hear it
“Both pieces work separately, but they disagree about the date format.”
Can you control it?
Sometimes
Sometimes. Some products or workflows let you influence an integration test, while others keep it fixed or manage it automatically. Check the settings and documentation for the tool you are using.
Common questions
- Can individually correct components fail together?
- Yes. Different assumptions about formats, timing or errors can cause a mismatch.
- Does an integration test need to cover the whole user journey?
- Not necessarily. It can focus on a particular connection or group of components.
- Can test environments hide real connection problems?
- Yes. Simplified services or permissions may differ from the actual operating setup.
