Mocking Dependencies and Facades in Laravel Tests
Mocking dependencies and facades can improve Laravel testing efficiency and reduce side effects, because real execution of external resources will cause the test to be slow, unstable and difficult to control the state; correct mockfacades should use Facade::shouldReceive() instead of ordinary instance mock; combined with Mockery can make the syntax more concise and intuitive, but you need to pay attention to cleaning up the state, avoiding excessive mocking and parameter matching problems.

Comparing and Choosing Caching Drivers for Laravel
The selection of Laravel cache drivers needs to be determined based on the project size and deployment environment. 1. File cache is suitable for local development or small projects. Its advantage is that it does not require external services. The disadvantage is that it is poor concurrency and is not suitable for multiple servers. 2. Database cache is suitable for scenarios with existing database connections. The advantage is that data can be persisted, and the disadvantage is that it affects database performance. 3. Redis is suitable for high-concurrency and distributed projects. It has good performance and supports clusters, but requires additional installation of services. 4. Memcached is suitable for key-value pair cache, which is fast but has limited functions and does not support persistence. Drivers can be switched according to the environment, such as local file and redis in production environment.

Local scope is a method in the model, starting with scope and can take parameters, such as scopeVerified() or scopeOfType(). 3. When using global scope, its impact on all queries should be considered. If necessary, you can exclude it by without GlobalScopes(). 4. Choose to do it
