في هذا الدرس

know what unit tests cannot show and integration tests can.

الموضوعات المخطط لها

• Unit tests check logic in isolation; integration tests check that parts work together with real infrastructure.
• They catch wrong SQL, missing migrations, mapping errors, and wrong configuration.
• They are slower, so write fewer and aim them at boundaries: database, web layer, messaging.
• Use the same database as production; an in-memory stand-in hides differences.
• Docker must be running for the tests in this module.
