Mock your Test Dependencies with Mockery
Article Introduction：While not everyone is doing this, testing your application is one of the most basic parts of being a developer. Unit testing is the most common test. With unit testing, you can check if a class is running exactly as you expected. Sometimes, you are using third-party services in your application, and it's hard to set up everything for unit testing. This is when the simulation comes into play.
Key Points
Mocking is the process of creating a substitute for real objects in a unit test, which is especially useful when testing applications that rely heavily on dependency injection.
Mockery is a library created by Pádraic Brady that can be used to mock objects in unit tests and is the default mock of PHPUnit

Best practices for using external libraries on window objects
Article Introduction：This article explores best practices for handling type definitions and ensuring library loading is complete when relying on external libraries on global window objects in JavaScript code. By declaring the global interface to extend the window object, it can solve the compilation problem and facilitate mocking in testing. At the same time, using dynamic script loading and onload event listening can ensure that the dependency code is executed after the library is loaded, avoiding runtime errors.

AngularJS Testing Tips: Testing Directives
Article Introduction：Key Points
Directives in AngularJS are critical for DOM operations and cannot be ignored in unit testing because they significantly affect the availability of your application.
Instruction testing involves setting up a test environment where instructions are manually compiled and mocking necessary objects and services to isolate the functions of instructions.
The link function in the directive is responsible for core logic implementations, such as DOM operations and event handling, and should be thoroughly tested using AngularJS's testing utility.
By integrating the templates used by the directive into $templateCache during testing, you can test the correct application and integration of necessary elements in the template, simplifying the testing process.

What is a Dependency Injection Container (DIC) and why use one in PHP?
Article Introduction：Dependency Injection Container (DIC) is a tool that manages and provides object dependencies for use in PHP projects. The main benefits of DIC include: 1. Decoupling, making components independent, and the code is easy to maintain and test; 2. Flexibility, easy to replace or modify dependencies; 3. Testability, convenient for injecting mock objects for unit testing.

Jasmine/Karma test: How to simulate external library properties on window objects
Article Introduction：This article introduces in detail how to effectively simulate external library properties defined on window objects in JavaScript in Karma and Jasmine environments. Ensure unit test isolation and accuracy by delving into common simulation failure cases and providing a robust solution for property setting and cleaning using beforeEach and afterEach hooks. This tutorial is intended to help developers realize reliable testing of global dependencies without modifying core business code.

Fun with Array Interfaces
Article Introduction：Key Points
PHP's array interface allows programmers to simulate the characteristics of native data types in custom classes, similar to Python's methods. This enables custom classes to work like arrays and allows common array operations such as counting elements, looping through elements, and accessing elements through indexes.
An interface is like a contract for a class, specifying the methods that a class must contain. They allow encapsulation of implementation details and provide syntax sugar, thereby improving the readability and maintainability of the code. PHP provides a library of predefined interfaces that can implement these interfaces to make objects similar to arrays.
Countable, ArrayAccess and Iterator interfaces in PHP allow objects to pass cou respectively

Jumping from PHP to Go: Blasphemy, Bravado or Common Sense?
Article Introduction：Core points
Migrating the underlying Laravel application of Boxzilla applications from PHP to Go ends up with a more efficient program with better performance, easier deployment and higher test coverage, despite initial concerns about potential business risks.
Go is a compiled language with a standard library that is better than PHP, and can generate faster, smaller applications with fewer lines of code even if external dependencies are considered. The conversion from PHP to Go needs to adapt to new syntax and features, but the end result is considered worthwhile.
Despite PHP's larger community and rich resources, Go's growing popularity, ease of use, and excellent performance features make it a strong contender for developers to consider conversions. The author predicts that the future will be

php function for curl post request
Article Introduction：How to send a POST request in PHP? The answer is to use the cURL library. 1. Initialize the cURL handle; 2. Set the target URL, enable return transmission, enable POST method and specify POST data; 3. Optionally set custom request headers; 4. Execute request and process responses; 5. Check for error information; 6. Close the cURL handle. When sending data, you can use array or JSON format. If it is JSON, you need to manually set the Content-Type header; if HTTPS requests encounter SSL certificate problems, you can turn off verification in the test environment, but the production environment should avoid it. Examples include normal form submission and JSON data submission.

Taming the Pyramid of Doom: Refactoring Nested If Statements in PHP
Article Introduction：To solve the "death pyramid" problem caused by nested if statements in PHP, the following five reconstruction methods should be adopted: 1. Use early return (guardclauses) to flatten the condition check to avoid deep nesting; 2. Extract complex conditions into a private method with clear names to improve readability and reusability; 3. Use verification objects or middleware mode for complex processes to achieve composable and extensible verification logic; 4. Use ternary or empty merge operators only in simple scenarios to avoid nested ternary expressions; 5. Use exceptions to replace error string return, handle errors in a centralized manner, and keep the core logic pure. The ultimate goal is to make the code safer, easier to test, and easier to maintain through rapid failure, logical separation and appropriate design patterns.
