Explain the testing process, including unit and system testing.

The $*$Melbourne Farm Supplies $-$ Online System$*$ follows this $**$testing methodology$**$:

$1.**$Unit Testing$**$: Individual components $($e$.$g$.,$ product management, order processing$)$ are tested in isolation to ensure they function correctly. Developers create test cases to verify each unit's behavior.

$2.**$System Testing$**$: The entire system is tested as a whole to ensure all integrated components work together seamlessly. This includes end$-$to$-$end testing of features like product searches, order placements, and shipping updates.

Both testing processes ensure the system operates correctly before deployment.
