                              NEW QUESTION # 81
                              開発者が Lightning Web コンポーネントの Jest テストを記述する必要がある 3 つの理由は何ですか?

                              Answer: A,C,E

                              Explanation:
                              Jest is a powerful JavaScript testing framework used for Lightning Web Components (LWC) to ensure individual units of code function correctly in isolation. One of the primary reasons to use Jest is to verify the DOM output of a component (D). Since LWC is a UI framework, Jest allows developers to inspect the rendered HTML to ensure that elements, classes, and data are displayed as intended after a state change.
                              Furthermore, Jest is essential for testing basic user interaction (A). Developers can simulate events like button clicks or text input and then assert that the component's state or UI updates accordingly.
                              Another critical use case is to verify that events fire when expected (E). Components often communicate with parents via custom events; Jest allows you to "spy" on these events to ensure they are dispatched with the correct detail payload at the right time. Conversely, Jest is not intended for testing how multiple components work together (C)-this is the domain of integration tests or end-to-end tests (like UTAM). Additionally, Jest tests should focus on the component's public API and observable behavior; testing non-public (private) properties (B) is generally discouraged as it leads to brittle tests that break upon internal refactoring. By focusing on DOM output, interactions, and events, Jest provides a fast, reliable way to maintain component quality.


                              NEW QUESTION # 82
                              Lightning レコードページのボタンをクリックしてモーダルダイアログに表示できるようにするには、Aura コンポーネントによってどのインターフェースを実装する必要がありますか?

                              Answer: D

                              Explanation:
                              force:lightningQuickAction is an interface that needs to be implemented by an Aura component so that it may be displayed in a modal dialog by clicking a button on a Lightning record page. The force:lightningQuickAction interface enables the component to be used as a Lightning quick action, which is a type of action that can be invoked from a record page, a list view, or a global action menu. By implementing the force:lightningQuickAction interface, the developer can create a custom Lightning quick action that can display the component in a modal dialog, and pass the record ID and other parameters to the component.
