But - to me
Error Handling Testing In Software Testing
this seems to contradict... Coding to interfaces, not implementations We code to interfaces or abstractions to reduce coupling. We don't know, or want to know, the specific type and implementation of an interface. So how can we possibly know what exceptions we should be looking to catch? The implementation could throw 10 different exceptions, or it could throw none. When we catch an exception surely we're making assumptions about the implementation? Unless - the interface has... Exception specifications Some languages allow developers to state that certain methods throw certain exceptions (Java for example, uses the throws keyword.) From the calling code's point of view this seems fine - we know explicitly which exceptions we might need to catch. But - this seems to suggest a... Leaky abstraction Why should an interface specify which exceptions can be thrown? What if the implementation doesn't need to throw an exception, or needs to throw other exceptions? There's no way, at an interface level, to know which exceptions an implementation may want to throw. So... To conclude Why are exceptions preferred when they seem (in my eyes) to contradict software best practices? And, if error codes are so bad (and I don't need to be sold on the vices of error codes), is there another alternative? What is the current (or soon to be) state of the art for error handling that meets the requirements of best practices as outlined above, but d

In programming, a development error is one that can be prevented. Such an error can occur in syntax or logic. Syntax errors, which are typographical mistakes or improper use of special characters, are handled by rigorous proofreading. Logic errors, also called bugs, occur when executed code does not produce the expected or desired result. Logic errors are best handled by meticulous program debugging. This can be an ongoing process that involves, in addition to the traditional debugging routine, beta testing prior to official release and customer feedback after official release. A run-time error takes place during the execution of a program, and usually happens because of adverse system parameters or invalid in
