Using tests as a debugging tool for logic errors

In Java development, logic errors constitute a unique class of defects where code executes flawlessly according to its written instructions while systematically violating business requirements. The disconnect arises when programmatic operations mathematically diverge from domain-specific rules. Think of a tax calculation that subtracts instead of adds deductions, or a scheduling algorithm that ignores daylight saving boundaries. Traditional debugging techniques often prove inadequate for these conceptual mismatches, necessitating a paradigm where test cases become verification protocols for operational semantics. The peculiar nature of logic errors Logic errors manifest from a fundamental disconnect — the gap between what you thought you told the computer to do and what you actually instructed it to do. Your code runs, but it’s running the wrong race. Consider this deceivingly simple calculation method where the intended purpose is to return the final price after applying a percenta ...
