Swift Testing：現代化測試框架，Swift Package Manager 推薦選項。

💡 Xcode ⟩ Product ⟩ Test (command + U) 可以執行所有測試 (Unit Tests)

If you choose to add tests to your project, Xcode will create two additional targets: one for unit tests and one for UI tests.

structure for a test case:

Arrange: arrange the "system under test" (SUT) and the "inputs".
Act: act on the SUT to get the "output".
Assert: assert the "output" matches the "expected result".

func testEmptyMenuReturnsEmptySections() {
    
    // ⭐️ Arrange: (arrange inputs)
    let menu = [MenuItem]() 
    
    // ⭐️ Act: (generate output)
    let sections = menu.groupedByCategory()
    
    // ⭐️ Assert: (assert match)
    XCTAssertTrue(sections.isEmpty)
}
