Using Laravel Dusk for browser testing.
LaravelDusk is a browser testing tool that requires no complex dependencies, suitable for simulating user operations. It provides out-of-the-box testing capabilities based on ChromeDriver. After installation, it generates test files and writes test logic through the Artisan command. Common methods include visit, click, type, press, and assert path or element visibility. When handling asynchronous interactions, you can use waitFor, assertVisible, or execute custom JS code. It is recommended to use .env.dusk to isolate the test environment. During debugging, you can use slow mode to observe the operation process. It is recommended to enable headless mode for formal operation, and priority is given to the use of built-in waiting mechanism rather than sleep(). In HTML

The N 1 problem and Laravel Eager Loading.
N 1 query problems can be solved through Laravel's preload function. When an associated query is initiated separately for each record after obtaining the main table data, the number of database queries will surge, for example, 20 article data are retrieved but 21 queries are performed. Laravel uses the with() method to load the association model at one time, such as Post::with('user')->get() to control the query within two times. Post::with('user.role')->get() is available when handling multi-layer nested relationships. Restrictions can be passed in closures when loading fields or adding conditions, but foreign keys must be retained. Easy to ignore points include Blade template access unpreloaded properties, dynamic accessor call relationships, and usage

Explain Blade Service Injection in Laravel.
Blade service injection is a function in Laravel for directly calling service class methods in the view layer. Through the @inject directive, such as @inject('variable name','namespace\class name'), you can get the service instance in the view and call its public methods. It is suitable for scenarios such as obtaining global configuration, displaying cache statistics, displaying widget content, verifying permissions or status. When using it, you should pay attention to keeping the view logic concise, ensuring that the service class has bound containers, avoiding repeated calls to affect performance, and prioritizing unified management of data through components, instructions or view composer.
