Why is testing important?
Testing is a critical part of modern software development. Well-written tests help you:
Catch bugs early before your code is shared or deployed.
Save time on team projects by ensuring changes don’t accidentally break existing features.
Two common types of tests:

Integration tests: Check how multiple parts of a system work together.
When writing tests, we often follow the Red → Green loop:
