Understanding different types of software testing is crucial for delivering a reliable application. Smoke Testing checks basic stability after a new build, while Sanity Testing verifies specific bug fixes or minor updates. Functional Testing ensures that features work as expected based on business requirements. Regression Testing prevents new changes from breaking existing functionality. End-to-End (E2E) Testing simulates real-world user workflows, and Performance Testing checks system speed, load handling capacity, and responsiveness. Implementing these (some or all) test types helps maintain software quality and prevent critical failures.

When it comes to writing clean, maintainable code, there are a few fundamental rules that can help improve the overall structure and quality of your codebase. As engineers, our goal should be to keep things simple, clear, and scalable. With this in mind, here are some guidelines which prioritize code readability, functional clarity, and the overall maintainability of a project. These guidelines are based on principles from clean code, SOLID, and functional programming while emphasizing simplicity over unnecessary complexity.
