PHPUnit does not support direct mock global functions, but can be implemented through namespace tricks or third-party libraries. 1. Use namespace to redefine the function of the same name in the test file to overwrite the original function; 2. Use tools such as BrainMonkey or FunctionMocker to simplify the mock process; 3. The best practice is to encapsulate global functions into the class and manage through dependency injection to improve code testability and maintainability.

Install PHPUnit and configure the project environment; 2. Create a test directory structure and correspond to the source code; 3. Write independent test cases and use assertions to verify the results; 4. Use mock objects to isolate external dependencies; 5. Run tests frequently to ensure code quality. First, install PHPUnit through Composer and configure phpunit.xml file. Then create the tests directory to store the test class. Each test class inherits TestCase and writes a method starting with test for testing. Use assertEquals and other assertions to verify the correctness of the logic. Use createMock to simulate behavior for external dependencies. Finally, execute vendor/bin/phpunit commands regularly.

Effective React component testing should be centered on user behavior and simulated using ReactTestingLibrary. 1. Priority is given to testing user-visible behaviors, such as button status and interaction results rather than internal structures; 2. Use query methods that conform to the user's search methods, such as getByRole and getByLabelText; 3. Use userEvent to simulate real interactions, such as input delay and event triggering; 4. Clean up components after each test and simulate external dependencies to ensure independence.

Test what users see and do, rather than internal implementation; 2. Use the correct query methods such as getByRole and getByLabelText to avoid dependence on DOM structures; 3. Use findBy or waitFor to handle asynchronous behavior to ensure stable tests; 4. Reasonably mock external dependencies such as fetch and timers to ensure fast and predictable tests; 5. Overwrite edge cases such as loading, errors, empty states, etc.; 6. Keep the test independent and concise, each test focuses on a single behavior and correctly use the render wrapper. By simulating real user interactions, ReactTestingLibrary helps you build trusted, easy to maintain, resilient UI tests for refactoring and practical use
