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

Summary from the TLDR Web Dev newsletter

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.
