JAVA UNIT TESTING: HOW TO USE TESTS AS A DEBUGGING TOOL FOR LOGIC ERRORS

Logic errors in Java occur when code executes correctly but violates business requirements, often due to misunderstandings of the intended logic. Unit testing can serve as a debugging tool for these errors by systematically verifying operational semantics and pinpointing the exact location of the flaw. Other methods like hypothesis tests, state progression tests, and regression tests help isolate and understand logic errors by exposing unexpected variable interactions and boundary condition failures.

CATEGORIZE YOUR DEPENDENCIES

Modern JavaScript projects have outgrown the simple dependencies/devDependencies distinction. pnpm's "Catalogs" feature is better for creating more meaningful categories (like "frontend," "backend," and "build").

INHERITANCE WAS INVENTED AS A PERFORMANCE HACK

Inheritance was initially invented in Simula as a performance optimization, not for code reuse or extensibility. The Simula language creators wanted to simplify their garbage collector and efficiently implement intrusive lists. Their garbage collector had limitations that were solved by banning certain function calls, which resulted in reducing the expressiveness of the language.
